Greg and his team did a great job for me and my fiancé - we must have met with 8 contractors both large and small companies and we are very happy with our decision. The job was done professionally, clean, and most importantly Greg is always available to answer our questions. If you are looking to solve a water problem in your basement these guys are reasonably priced and do quality work. read more

We had a leak around our front bay window and weren't sure who to call - window guy? Roofing / siding company? Got a referral from a friend to Greg at General Moisture Solutions (Lackosz Construction) and wow, he was great. Responsive, responsible, did great work on time, fully explaining everything he was doing, the options, costs, etc. He supervised all of the work, with one of his Polish guys doing most of the work, with Greg chipping in when needed to complete the job. Apparently he is also BBB rated and on Angie's list. So if you have any sort of leak or moisture problem whatsoever, I'd highly recommend. We've had some TERRIBLE contractors / service professionals during our years of Chicago homeownership, so I'm really happy to be able to recommend a GREAT one to my fellow YELP-ers this time! read more

Greg and his team were great to work with. He is extremely responsive, detailed and fair. After a mishap with leaving a faucet on in our basement, Greg was able to get a team out the next day to do a full remediation of the water damage. At that time, we also had him take a look at some minor seepage issues that we'd seen with the heavy rains in the fall. Instead of a pushy approach we'd gotten from other contractors, Greg helped us evaluate our options and we came to the conclusion together to install drain tile in addition to refinishing the basement. His team started during the holiday season and installed the drain tile, replaced damaged drywall and trim, painted and laid carpet in less than 3 weeks. The team was friendly and even fixed some other minor items around the house free of charge. During the job, Greg was constantly in touch, always quick to respond to phone calls and texts and personally visited nearly every day, despite having more than one job going. Since we were anxious to get the basement back, he was great about keeping us updated on progress and setting expectations. At the conclusion of the work, Greg had a cleaning lady over to clean the basement and main floor, then walked through all the work that had been done to make sure it was satisfactory. He even offered to replace any sod that was damaged in our front yard due to the construction debris once spring comes. I would definitely recommend Greg for any water issues or general contracting projects that you may have. read more

Greg is very good at what he does, and he stands behind his work. When no one else could pinpoint a leak in our ceiling, Greg investigated and found the source and fixed it! His work isn't cheap, but it's completely worth the cost to have our leak and water damage finally fixed! read more

Installation Services are best. i highly recommended General Moisture Solutions.

The best. Super profession and get the job done. Greg & his team are upfront & honest, and will under promise & over deliver. We dealt with two separate water seepage problems, and after our first contractor couldn't fix the problem, GMS did. 5+++ read more

After finding mold in our home during our final walk through right before closing, we were really concerned. We had one week to find a contractor and to remediate the mold/move in. From the moment I called GMS they were easy to work with. Greg happened to be in the area when I called him and he came over within 15 minutes. WOW. This was the first company that I had dealt with to date that had been easy to work with, honest and were willing to work in my timeline. He sent me a quote that evening that was honest and below other quotes I had received. He reassured me it wasn't going to be a big deal to get rid of and started/completed the job the very next day. Again, unheard of. This will be the only company I work with in the future should we have moisture problems in the future. Thank you GMS!!! Would recommend to anyone needing an honest and hard working team!! read more

Even though Greg was very busy addressing issues in many buildings during Chicago's crazy February of ice jams, he was able to give me some advice to address two different leaks. I really appreciated that advance advice and that he found a few minutes to stop by and suggest what could be done in the interim before he could get to my repair with his team. I was able to get restoration started quickly. Once the ice had melted and the leaks stopped, scheduling was prompt and the team was always there at the appointed time. Greg was able to quickly repair the drywall for both leaks. The repair was completed timely for a reasonable cost. Hopefully I won't have leaks in the future, but I know who to call if I do! read more

Wow! I cannot express how thankful I am for Heneral Moisture solution. We had water coming in from our front bay window, every rainstorm would produce a small stream in our living room. They came out right away, gave us an answer to why this was happening and sent us an estimate a day later. They came out a couple of days later, fix the issue and removed the mold. I am now sitting at said bay window watching the rain OUTSIDE! Thank you General Moisture Solutions for saving our living room! read more

Can't speak highly enough of Greg and team. If you've ever had water issue, you know that its very difficult to get anyone to properly diagnose and efficiently manage your problems. Greg was communicative, timely, transparent, thorough and completely fairly priced. Highly recommend. read more

Greg and his team were great to work with from start to finish. They performed a lot of work, from flashing my windows, to replacing entire exterior doors. Even after my project was done, they were always willing to come back to follow up with any questions I had and made any necessary adjustments after a door settled in to fit the frame as it should. read more

My unfinished basement (of an old house with brick basement walls) occasionally floods in 2 spots during extremely heavy rains. Greg proposed the installation of drain tiles (perforated pipes). They dug a trench about a foot down through the concrete floor, laid a perforated pipe and connected it to the sump pump. They also attached a moisture barrier on the brick wall extending down into the trench. The trench was then covered with concrete. The intent is to direct water seeping in during heavy rains from the brick walls down into the perforated pipe and into the sump pump. The crew did a great job! They worked quickly, cleaned up well and the space looks nice. My only lament is the new concrete poured on top of the trench is of a different color and finish than my original floor, but that can't be helped. I also hired Greg for a small masonry job to repair exterior bricks that have come loose and are crumbling. He and his crew repaired it with great attention to detail. It looks excellent. I would definitely use General Moisture Solutions again! Highly recommend! read more

During some heavy rains this past weekend, we discovered a leak in our condo building roof that was letting water into our utility closet (where our water heater is located). We asked Greg to come out and evaluate whether we had any serious water damage. He quickly assessed the problem and could have charged us a few hundred dollars to patch up the caulking on our roof, but instead let us know how we could do it ourselves to save some cash. He was super nice, on time, and very helpful. read more

Called GMS on a Tuesday with a leak in my roof. They were on site and had the problem identified, fixed, repaired, and painted before the end of the week. I worked with Greg. He was extremely friendly and provided a lot of information to make sure I was comfortable with what was going on with the issue. I would recommend them to anyone. read more

Buying a bank owned home has come with a myriad of problems. It has definitely taught me how to be savvy when selecting a construction professional. We had a leak in the basement which looked like it was coming from behind the drywall. I had 3 different companies come out to quote me on the job. General Moisture was not the cheapest nor the most expensive (All three were highly rated on Yelp and Angie's)..We met with Greg and he knows his stuff. Of the 3, he was the only one that thoroughly explained what he thought the issue was and how they would attack it....Turns out he was 100% right. No one wants to cut through dry wall to find out they're wrong! It turns out we had 4 foundation cracks causing the issue...One guy thought we needed drain tile, which we already have...Another said "we'll fix the cracks, but you need to remove the drywall and replace it"....let's just say we're glad we went with General Moisture Solutions. From the beginning to end Greg and his team did a wonderful job. Greg is a personable guy, who puts his customers first. When he came out to the job he never answered his cell phone while speaking to me, when others were calling him. His employee Chris came out to do the work. Chris is a pro and Greg made a great hire with this guy. He explained step by step on what was going to happen and what he was doing. He was conscientious and kept the area clean...He also took the time to answer any questions I had....After Chris finished up, I decided to leave the drywall off to test the leaks. We had that brief warm-up, with rain and no leaks. I also ran the hose that day to make doubly sure we had no leaks. I called Greg to give him the good news and he was able to get his guys out the next day to replace the drywall. I asked them to double encapsulate the area to lessen the drywall dust...Without hesitation they encapsulated the area again and sealed up the HVAC returns. My painter is here today and he said the drywall replacement work looked exceptional....Greg and his team are professional, honest, hard working and dependable. Without hesitation, I would recommend his company for any leak problem you may have! read more

We spent a lot of time and money working with contractors to try to fix a leak in our condo. After a couple bad storms, the water was still pouring in and after searching for specific water damage contractors I found GMS on yelp. I called and Greg was out the same day to assess the situation. He knew what the issue was and got me a quote within a couple days. It was a big job (huge sliding door needed all new flashing) but his team got it done right and we haven't had any water since. They were courteous, clean and I would highly recommend they be your first call for any water damage issues. read more

A good contractor is so hard to find, but we really lucked out when we contacted Greg at General Moisture Solutions. 2 years ago we purchased a new townhouse. Upon moving in, we were devastated to discover some water issues that were covered up by the prior owners and went undetected by our home inspector during the purchasing process. Every time it rained, we would have water leaks in various rooms throughout our home. Thus began a 2 year saga of hiring contractor after contractor who would offering up incorrect solutions, costing us thousands of dollars, and ultimately not fixing the problem. We tried everything including replacing and repitching the roof, recaulking windows, clearing drains, and sealing the exterior brick. We were at our wits end, along with everyone else in our townhouse association, most of whom were experiencing the same issues and frustration for even longer than us. Just when we were ready to give up, we found Greg. Within 5 minutes of walking into our home, he correctly diagnosed the problem and offered up his solution. Given our contractor experience so far, we were only convinced once Greg told us that if his solution didn't work, "your problem becomes my problem." What contractor says that!? Anyway, it's been a month since Greg and his team completed work, and I'm ecstatic to say, our water problems are over! Just as I was beginning to think our home was simply defective, all it needed was the work of a knowledgable contractor. We couldn't be happier with the work that GMS did in our home. The crew was extremely pleasant and efficient. They tidied up every day promptly at 5pm. When mold was discovered in one of the walls, they immediately went to work doing mold remediation. Greg was there at least twice a day to check in with us and the workers to make sure everything was moving along according to plan. I would happily recommend him (and already have) to anyone looking for a contractor who stands behind his work! I will say that he can sometimes be difficult to get ahold of, but don't let that dissuade you. He is a busy guy for good reason. Thank you Greg and your team!!! read more

could not be happier with GMS- on time, on budget, and on schedule. great work, and very friendly. Awesome job guys!

We occupy the penthouse unit in a four story building and (unfortunately) have had a handful of water issues over the years with the flat roof. The first time we had signs of intrusion we had a few companies come out to provide quotes. Greg was the most upfront and informative. He thoroughly explained the cause of the issue and more importantly, solved the issue at a reasonable price. Because of the excellent experience we had with GMS it was a no-brainer to call Greg when we saw any sign of water. He doesn't over-promise, his team is considerate, and you get the vibe they're just great, down to earth guys. I highly recommend GMS and am grateful for their excellent service over the years. read more

Greg came out to a property I own to examine a window that was leaking. I never got a chance to meet him as I could not make it that day, but he came back with a quote for $2200, suggesting that we basically replace the window, reframe the window box, and do a whole re-do, I guess. I say "basically" and "I guess" because I never got a translated answer from him on what he was even proposing or why it needed to be done. After I got the quote via email, I asked him to call me. No response. I then wrote an email asking him to give me a more thorough explanation - was it a building issue? A window issue? What was the source? You know, this stuff kind of matters since it's a condo and I need to know whether my personal insurance covers it or the HOA. I got an email response saying he would call me, and he never did. Since I was getting nowhere with Greg, i called in 2 more contractors who each suggested a more practical approach. They pointed out a few exterior cracks in the building above the window, suggested we mortar these, and then see how it went before we took the next step. I told them both about the $2200 quote and both separately said that going that route was a terrible idea. Greg may be a knowledgeable contractor and may have a great and valid reason why he quoted me $2200. Maybe the window needs exactly what he says. A lot of people on Yelp have positive things to say, so I'm sure he doesn't treat all his prospects like this. But since he is too busy to call me back we will never find out! read more

We had Greg and Chris out from GMS to tuck point the front of our home as well as the top of our chimney. They also did some spot injection in our basement foundation. Overall it was a good experience and we'd certainly look to them again in the future. read more

Beware... Greg will come in and promise that everything will look like it did before the water damage, and then give you a very reasonable quote for a lot of proposed work. When the work is actually done, it will only be on about 1/4 to 1/2 of what was originally discussed. If you try to fight him on it, he will point out the words "approximately" or "about" on the estimate to weasel out of doing the completed work. His estimate will also NOT include painting, which he may or may not do afterwards and if so, will definitely charge you more for. Ultimately, Greg comes across as a little sleazy, and his actual business practice backs that up. Like a typical contractor, I had to withhold final payment until all of the work was totally completed, even though he called several times for payment knowing that the work was not done. Not to mention, the guys he has working for him do very sub-par workmanship. There's got to be someone out there better... read more

Greg came to my house to look for the source of an ongoing leak problem. After a short, cursory examination he said he knew the problemt. A few weeks later he emailed us an estimate for $1,400 to put in flashing under a balcony door. When I responded that I was willing to work with him but needed a written guaranty, I never heard back. Very suspicious and frustrating. read more

Where is the 6 star option?? I even tried to 0.5 star trick by stroking to the right to get 5.5. I can't wait to work again with Greg. Project: 8 week, 2500 sq ft, high end town home renovation with Greg who worked in a General Contractor role. The property had been gutted and needed everything redoing. Three bathrooms needed to be redone entirely, flooring throughout the entire house changed (some hardwood some carpet), walls were moved and erected. Working relationship: Greg was the sixth contractor to come out and give me a quote. All of the other contractors wanted to measure, count and document everything as if the quote was heading into a spreadsheet somewhere. Greg gave a competitive quote without wanting much detail - which to be honest, at first made me pretty nervous. Fortunately I decided to go with it and Greg's casual manner was what really made this project a pleasure. A couple of examples of great things that happened: - I wanted extra rooms doing and Greg gave a very reasonable quote for these and did not complain - Greg did not modify the price for additional "little things". An example of this would be installing appliances where it was not in the contract but Greg just took care of it anyway when they arrived. Nothing was ever a big deal. Another example of this was a burst pipe that became evident when we turned the water on. Greg simply took care of it including the wall repairs that were necessary. - Greg offered great, cost saving advice throughout. He was aware of what I was looking to do with the property and helped optimize for that. The place would not have turned out as nice if I had not listened to his advise. He managed to recycle a vanity unit (no extra charge) from one of the bathrooms, he sourced a great discount on some cabinets for the kitchen, he even helped me pick out the carpet at a heavily discounted outlet, the list goes on. I am pretty sure that even if I had the time to manage this project myself I would not have been able to do it for the same price. - Greg was able to find the perfect balance of autonomy. I am very busy during the week and have 0 time (literally zero minutes) to be away from work. As such for small to medium decisions I asked Greg to just call the shots. Throughout the project it became clear that he was making better decisions than I was. By the end of it I really had very little input (by choice) and Greg would only contact me for anything large like which colour granite. Unless you have a very specific picture in mind of what you want I would advise letting Greg run with it. - Great communication all round. Greg and I would text mostly and use picture messages to make decisions on products. I don't think I ever waited long for a text back or a call back. - It is evident that Greg takes his projects with passion. It was clear that he cared how the finished product looked and how it all came together - this was not simply a case of checking off items on the quote list like other contractors do. Quality of work: A high quality finish for a high end home all round. The walls were in dire shape and are now immaculate. The house is clean after completion. I have nothing negative to say about quality of work, I could not find any signs of poor workmanship. read more

I don't leave Yelp reviews unless it's a must. Greg and his team are unbelievable. They were awesome, 5 stars in every sense of the word... Honest, fast, efficient, affordable, etc. I asked him for maintenance advice on two other minor jobs and he just did them quickly without asking. Makes me feel good knowing there are still people and service providers out there like GMS read more

Last summer we got 3 quotes to repair our roofing pitch. Greg was in the middle and we decided to use the cheap guys who ended up melting our siding while repairing the roof, didn't tell us, and it resulted in water damage appearing on our ceilings within months. I called Greg once again, a bit embarrassed, and he came back out and requoted all the initial repair work & new damage. We thought we were saving $600 in the beginning to end up $3K in the hole. Greg's worked with us in advising how to deal with our insurance, works around the weather and is prompt. Very professional & personable contractor- highly recommend the first time around! read more

If you have any kind of water damage GMS should be your first call. Greg knows his stuff. Highly recommend

Like others here, I called to ask for a quote, he told me to email through the website. I emailed through the website and never heard back. I Found someone else much more responsive. read more

Greg answered his phone and scheduled an appointment for the next day. He showed up on time and took a look at my problem, and let me know that is was just something that naturally happened with windows and there was nothing I had to do about it. He could have told me I needed to replace a bunch of stuff and I would have listened and paid, so I really appreciated his honesty. I would recommend using him and would again in the future for any problems I have. read more

Greg and his team did a great job of uncovering the source of our leak (a bad job from our last contractor) and fixing the problem. His team was very professional and explained every step thoroughly. read more

Big thanks to GSM! I live in a duplex and had several issues with leaks near our roof deck on the forth floor. With many trials and errors on my own, I finally discovered that it was our door and windows leading to the deck that were improperly installed. GSM replaced our door, and installed flashing in our door and windows and now we are leak free! I wish I had called them sooner so they could have helped me diagnose the issue earlier instead of suffering for a couple of years. I highly recommend them as they were great to work with - professional, efficient, and knowledgeable. I no longer get anxiety attacks at the thought of rain. I have never written a review on yelp before but has to share my great experience for anyone who had bad leak issues like I did. read more

After a recent -50º windchill blew out pipes all over Chicago, I needed help. Greg is GREAT! Responsive, on time, and professional. Plus he's a very nice guy AND totally honest about the amount of work I really needed (I thot I needed lots - he told me he doesn't fix what doesn't need to be done - how wonderful is that!?!?). I'd definitely highly recommend GMS to everyone. read more

Greg and his team just came out and fixed two windows (one of which had a rain water leak). The frame of the windows were no longer sealed properly to the brick wall, causing wood to get rotten. They replaced the compromised parts of the frame and sealed around the window. They did also tuck pointing the brick wall around these windows to make sure that no water is seeping through. I first contacted him through his website (listed above), and I got his reply on the same day!! He came out to inspect the problems a few days later and prepared an estimate. His response was quick and honest. He listened to me and explained to me what he believes would solve the problem. After contacting several contractors, I found that he was so "professional" compared to many others. If you have some wet problems, he would be the guy to call. read more

Our building had what recently became an annual leak into the third floor bedroom and bathroom. After 2 years of using another contractor who simply patched and never found the source we found Greg on Yelp from the other reviews (we ignored Oscar's patently obvious competitor's review). We obtained a few estimates and Greg's was the lowest with a guarantee. He was extremely patient and flexible with our association in starting the job - adjusting his schedule to accommodate us on more than one occasion. Once he and his crew started their quality and efficiency was shown - top notch. They protected their work area inside and outside and cleaned up each day inside the bedroom and outside. This wasn't an easy job by any means with it being on the 3rd and 4th floors with just stairs and a young child to be conscious of and yet they didn't say a word. This is their specialty and they are very dedicated to their craft. Their work is also very safety conscious in how they perform it to themselves and the surrounding properties as we needed exterior work which was the source of the leak. Yes, greg found what the others couldn't --- the source. His estimation on time was very accurate as well and his workers are very polite, professional and extremely good at their trades. There really isn't much more to say other than this by far the best contractor we've ever dealt with on any repair issues related to our building. I couldn't recommend Greg and his crew more. 5 stars from a very happy condo association. Great work! read more

Greg and his team saved the day, early this year, during the polar vortex. One morning we woke to the sound of rushing water - A pipe had frozen and burst in our building. Greg answered our call immediately, and was out to our place in less than an hour to begin cleaning up the damage. His crew was extremely courteous, taking care to plastic wrap everything in the other parts of the house, while they worked on tearing out drywall. The entire process ran so smoothly and Greg was very accessible. He had a great deal of insight that helped us make smart and economical decisions during restoration. Workmanship was high quality, especially the attention to detail. Reliable, pleasant, knowledgeable and fair price. Highly recommended! read more

I used their services to address two cracks in the basement due to which we were getting moisture. They were prompt/ professional and took pride in their work. Greg did a great job of following up read more

Had an inspection by these guys due to water damage. Guy says 'yeah, no problem, I'll get you a quote tomorrow', radio silence for several days, when I followed up.....he's like oh yeah, I remember you...meanwhile mold is probably growing. No urgency here...I guess they are making so much money, they can turn down work. read more

Greg and his team are honest, hard working and quick to help solve solutions. We had some issues moisture and temperature issues (bathroom always was about 10 degrees colder than all other rooms) in our bathroom and decided to move forward with a gut renovation. They used the best materials to properly insulate our bathroom and now it is so much warmer now! They also build the custom shower for us, new flooring and tiles around our bathtub. The remodel looks amazing and we cannot be happier. Highly recommend this company! read more

We hired GMS to install a drain tile system and rebuild our building's storage area. They were knowledgeable about the project and worked efficiently once we were ready. On top of that they also came late to help install dehumidifiers. I would definitely hire GMS again! read more

One of the best contractors I have dealt with in the Chicago area. Greg explained eveything in detail before starting and went above and beyond what I would have expected especially for the price. Most jobs would have required hiring another contractor to do the finish work (replaceing molding and such) but Greg also did this work and addtional work on top of that. Could not have been more satisfied with the service and Greg. read more
