I went with Scientific Home Services a second time in 2021 after replacing my kitchen and bedroom windows-and their quality, craftsmanship is top notch. I would recommend this place to any family or friend if they are replacing windows. They may be pricier but you pay for the great service and professionalism and good quality windows. When I got my large picture window replaced, the team made sure to put covers on their shoes, left no mess, cleaned up and got rid of the old window. I am now 5 years in and the windows are in just as good of shape since when I purchased. read more

Easy to work with, communicative, competitively priced. The guys were pros during installation as they had to work quick due to Mother Nature. I was worried about a mess given that it was a bit wet outside but they treated our space with care and hardly left a trace! read more

Scientific Home Services did an excellent job quoting and installing my new windows. Jon was excellent to work with. Other companies I recieved quotes from felt like I was working with a middle man like buying a car. The guy you talk too has no authority. Not with scientific home services. Working with Jon he could provide direct answers and had the authority to make decisions. Jon even came up with a window layout that I had not thought of which looked better and saved a little cost. The installation crew was great. They covered everything in my house with plastic and cleaned up after themselves. They were able to replace the windows in 15 openings in one day. read more

Guys were very professional, efficient, and most importantly they saved me money making my home efficient.

My family ordered 17 windows and a sliding patio door. Jon was really great to work with. He showed up on time and was super patient with answering all of our questions. We kept delaying the project and he was patient with that as well. The team did a great job installing and cleaning up. They did measure our patio door wrong so when they came to install the door with the windows, turns out it didn't fit. So we did have to wait a while longer for them to custom order another door and come and install and clean up. But it all went fine in the end. Other than that, we would highly recommend this company!! read more

Scientific Home Services did a fabulous job replacing my windows and sliding door. From working with Jon during the quote process to installation, everything went smoothly. I was nervous about replacing, but Jon, Mark and the installers made the entire process pleasant. The installers were efficient, professional and clean, and everything was complete in a few hours. I'm the third homeowner in my subdivision to use Scientific Home Services, and highly recommend to others! read more

Reached out for an estimate, sent photos and descriptions of the work that needed to be done, and never heard back.

I will keep it short and sweet. Extremely happy with the results with using Scientific to replace a large number of windows on our home. Jon made great recommendations that were appropriate for our home and ultimately saved us money. Never pressured us. The installers did outstanding work. Beautiful installations and very clean and courteous. Far better decision to go with a slightly smaller company for these services. Do not hesitate to use Scientific. read more

Service was great from beginning to end. Jon came out to give us the estimate. He asked us what we were looking for and showed us a sample of the window. He knew what we needed and walked us through it. We decided to go with them and the windows were ready early. They came out to install six windows and it only took a couple hours and they left everything clean. Love my new windows. read more

Victor and his associate did a great job in repairing windows for our new home purchase. He was very thorough in explaining our options on the estimate, punctual for the repair job and finished 6 of our windows in just a few hours. I highly recommend Scientific Home Services and you're in good hands with Victor. read more

Mark was great. He was knowledgeable about windows and helped me choose well within my budget. The resulting windows are great--I have no complaints. read more

We recently had 26 windows and 2 doors replaced by Scientific Home Services. Jon came out for the initial quote. It was a matter-of-fact, no pressure visit with a fee similar to other companies. While we were ready to replace the big picture windows in the living room, Jon assessed that they were all in good condition and did not need to be replaced. Jon also gave us tips on changing a few of the double-hung to casements and we love the results. His crew was timely each morning, respectful of our property and thoroughly cleaned up each evening. I would highly recommend using Scientific Home Services. read more

I strongly recommend Scientific Home Services for window repairs. Their Field Services Supervisor, Victor Jimenez, did an excellent job of fixing our windows so they now open and close very easily. He was professional and knew immediately how to fix the problem. read more

I have used Scientific Home Services for both window repairs and for installation of a new window. they have provided excellent service for both of these services. I would definitely recommend giving them a call if you need new windows. they were prompt, reliable, knowledgeable and made sure my questions were answered. read more

Wowzers on the reliable and friendly customer service, standing by their quality product and long term business reliability. Just outstanding.! I was told this by another customer but until you experience it for yourself you just don't realize how incredible they are~ Thank You! read more

I am leaving a second review for this company. After they installed new windows in July we had a hornet problem. we thought they were coming in through the windows. Scientific sent Victor to check. Victor was exceptionally kind, patient, and thorough in his diagnosis of the problem. After adding additional weather stripping, he found that the hornets were coming in through the wall outlet. Looks like they were nesting inside the brick wall and were coming in through a gap between the outlet box and drywall. Thank you Victor for your exceptional service! read more

Have been using Scientific Home Services, working with Victor to fix my condo's windows for a long time. Victor has always been responsive and helpful. He's also provided advice for replacing some windows which Scientific could not service or replace. They are my go-to company for windows. read more

Had 10 windows replaced in my home. Great quality and a great installation crew. Also got an estimate to replace my picture window in the front of my house. I'm going to do it in the spring. Would highly recommend read more

I had a fantastic experience with Scientific Home Services (SHS) from start to finish. I was looking to replace all 11 double-hung windows in my 4th-floor condo and checked several different services before deciding to get a quote from SHS, largely because of their many excellent reviews. Jon came out to my home and sized everything up, and walked me through both the available products and the process of window build and installation. As I was only having the windows replaced, there was no need for new framing, and thus also no need for a permit (Jon knew everything and was happy to answer my many questions). Jon was able to explain the differences in products and helped me select one that would be a great fit for my needs. The process of ordering and paying was simple. Once ordered, the windows took about 8 weeks to be built, delivered, and installed. The installation was frankly incredible to watch. The two gentlemen that came and did the installation were very professional and efficient. The installation occurred on a cold November day. The installers removed all the old windows and installed the new windows in less than a day. Everything was well cleaned after installation and they patched a small ding that they caused in my bathroom wall. The windows themselves are incredible. My old builder-grade windows circa 1996 were beginning to literally fall apart, and the difference has been so incredibly noticeable. The noise in my unit has dramatically reduced, and there is no longer any notable airflow through windows except in the strongest of winds. The operation of the windows is easy and smooth. I couldn't possibly be happier to recommend SHS and have done so to several friends and neighbors. read more

We called Scientific after having a terrible experience with another window/sliding door company. Price was very reasonable comparing multiple companies. It took a while for our sliding doors to arrive, but once they did they installed 2 doors very quickly in 1 day (other company took 2 days to finish just 1 sliding door). We will be using Scientific for our future window replacement. read more

Great service. Prompt response. Fair price. Highly recommended. Everything went smoothly.

We hired Scientific Home Services to install six picture replacement windows. This work was performed May, 2024. We were beyond impressed by the two installers and their expertise. The quality of our new windows is outstanding. These are excellent windows for providing insulation for summer heat and winter cold. Shar and Hank read more

Incredible service. It's rare to find true 5 star service in construction in my experience. We had a leaky sliding glass door with a transom and it took a little work to find someone who works with transoms. We got several quotes and while all 3 had great reviews, professional sales people, and similar price points (outside of Apex which was double!), we eventually went with Scientific even though they were marginally higher in price (I'm talking less than 10%) because of their great warranty and the fact that we met with the owner of the company for the quote. Door was ordered and came very quickly, and we set up installation for a few days later. I left for work and asked my partner to call me when they finished. When I got a call 2 hours later I assumed there was a complication, but no- they were done! I was floored at how fast they worked and we love the new door and wish we'd have done it sooner! I sometime worry when there are so many 5 star reviews that they're gaming the system but this company is legit in our experience! read more

Excellent window + door installation. We had about 20 windows + 2 doors installed. The workmanship was superior. The new look is amazing. We checked around and selected Scientific Home Services. Thanks to everyone. read more

I had a great experience. The price to replace the glass was reasonable and it was a quick replacement once the new glass came in.

From estimate through installation, the process went smoothly. John gave clear explanations of the products Scientific Home Services proposed to use, the one-time transferable lifetime warrantee, what to expect during the installations, and total cost. We experienced zero pressure. John was readily available if a question arose. He also communicated with our HOA Board to ensure the windows met its standards. The two installers arrived on time, covered all furnishings and flooring, installed the eleven windows, and thoroughly cleaned the work areas. They worked hard and completed the job in one day. Most important, the windows look great. We highly recommend Scientific Home Services. It earned a five-star rating. read more

They were great . Even though we took a different route with our front window, I would use them in a heart beat...I may still use them this coming spring. They were honest and truthful when describing what we needed Cary Z. read more

Jon was very profession in providing an estimate. There was no hard sale. Juan the window installer arrived on the schedule time. He explained what they plan to do and covered the work area inside the house. He vacuumed and wiped down the area when he was done. There work was exceptional. I would highly recommend this company. read more

Responsive, knowledgeable, and efficient. Very easy to work with and impeccable work. I would highly recommend Scientific Home Services Ltd and look forward to them completing the back of our home. read more

You know it's time to replace your windows when you see the curtains moving because of the outside wind! Scientific HomeServices came promptly to assess the situation. I needed 16 windows replaced.The estimate was very fair and they did NOT try to sell me more than I needed. For example they told me only the glass and not the frame of the bay window needed replacing. So honest!The windows were ready sooner than others had told me. Because they knew I had a limited time for the work they sent out the whole crew and were done in less than half a day. Everything was cleaned up and they even replaced my blind hardware. It was the first time I could remember that I didn't have to ask someone to return because of incomplete work! The windows are beautiful and open easily. They are clearly more soundproof than what I had before.I am positive no more winter winds will creep into the house. I have been recommending this company to my friends and relatives nonstop! read more

The installers just left. They did a fantastic job and left my house and yard even cleaner than they were when they arrived. Very pleasant and professional. Same was true of Jon, my sales consultant. Despite being very personable, he kept his pitch extremely short and sweet while offering me the lowest estimate of the four companies I contacted. All in all, I couldn't be happier. Highly recommend! read more

I highly recommend Scientific Home Services. Why? 1) They're prompt 2) It's not a hard sell. Jon comes out, measures, sits down with you, takes you through your options, and says to let him know what you'd like to do, whenever you're ready. And then he's on his way. He was here for maybe 30 minutes. (and not to take away from this review, but another company that we regretfully used in the past was at our house for 3+ hours) 3) They remeasure before ordering 4) The installation crew are professional and friendly 5) They take care of any potential lead hazards 6) They know what's to code for stairwells and adhere to it 7) The price is totally reasonable 8) It was an overall great experience and the windows look great! read more

Second time we've used Scientific. This time they replaced our back kitchen door. This is not a standard door: it opens outward, on the right side, and was unusual dimensions. Scientific was able to get the style I wanted and it looks great! Very professional, great communication, very responsive. read more

Installed a new entryway door on our 110 year old brick home. Looks great and would recommend.

I have definitely found the perfect window repair service in Chicago! I am selling my condo, which is in a high rise downtown, and the inspection called for repairing or replacing the sash balancers (I guess they were sticking). I contacted several window companies to get an estimate. One did not respond. Another said I had to get the sash balancers replaced (at $800 per window) after sending photos and the inspection repairs. Victor from Scientific Home Services responded called and said the job was easy and would come out the next week to take a look... Well, I just left my condo after Victor's service call. He explained that the windows just needed some lubrication. He sprayed all four window sash balancers with some silicone spray and lickety split the windows were working with ease. He only charged me their service call fee, which is $120. This pails in comparison to $800 per window! I asked him about replacing the sash balancers and he said that they typically run $80 each and so the whole job for four windows (with labor) would be much less than the other company's quote. Thank you for the excellent service and honesty! I greatly appreciate it and am looking at Scientific Home Services for window repair at our new home. read more

From start to finish, Scientific did a great job with providing us an estimate, coming out to measure and ensure that they are ordering the correct windows, to a very well done installation. Only reason for 4 stars is that we had to call a few times before getting a response on teh status of our windows, which we found out were delayed by teh shupplier. More proactive communication would have been better. We called them back to come do our basement windows, so we are definitely lifetime repeat customers! read more

We had 20+ year old Pella windows that we thought needed to be fully replaced. Jon came out to give us an estimate and was only one of two companies that were honest and told us that we shouldn't replace our windows. Most companies were just trying to make a sale. He was extremely prompt, cordial, and knowledgeable - if there is any service I need done that this company does, I will definitely be choosing them in the future. read more

I got three quotes for my windows and on the referral of someone else in my condo complex who had used Scientific, went with them and couldn't be happier. Jon came out to do my quote and walked me through my options. I never felt pressured at any point and felt well informed of my options and the benefit of the windows Scientific would install. From the quote to the final install everything went smoothly. I adore the windows and they have made a HUGE difference in retaining heat during winter. Thanks guys, great job! read more

Fifteen years ago, they were great, they made the thermal glass to replace the ones i needed for my old early '80s aluminum windows. The only company in Chicago that could make that specific thickness I needed without having to replace the entire windows. Fantastic. Today; I needed six thermal glass for for windows in my new home and since they are on the 2nd floor, to have them installed (as they said on their website). I was told they don't make glass anymore, just sell windows. That I should call a glass company (but who would install them? I was calling to get all-in-one service). Another example I guess of how America doesn't make things or repair old things. So I'll be getting my glass from Chicago Tempered and hiring a local handyman. Two steps, but I'll get to keep my old wooden windows and that'll be worth it. read more

We replaced all the windows on our first and second floors (14 total) with Climate Solutions vinyl windows. The old windows were original construction (70 years old) single-pane windows so our house was drafty even during mild winters. The difference after installation was night and day: cooler in the summer, warmer in the winter, and our utilities bills decreased. Everyone at Scientific Home was extremely professional. They were honest during our initial consultation and reliable when it came time to install. We have an infant in our home, so we were especially concerned about lead exposure, but they couldn't have been more careful about covering our furniture and cleaning when they were done. Around 9 months later the caulk seal around some of the windows had shrunk and began letting in cool air, but Victor offered to come out same day to fix it at no charge. Pricing was fair and competitive. Almost a year later, we're 100% satisfied with the windows and service provided by SH and I'll continue recommending them to everyone I can. read more
