Their prices are reasonable and they must be good because we have to wait over two months to get our job started.

Pascal and M Leon's office was great to work with. Scheduling was easy, the bid was fair, and they came when they said they would. They installed another post to support the north side of the house. The work was carefully done and Pascal fully explained the process and what his workers had done. My realtor recommended this company since she works with them often and finds that they do consistently excellent work. I would hire them again for additional foundation work. read more

External basement wall repair around poorly installed window. Even though it was a small job Pascal took his time in reviewing the work that needed to be done and explained everything in great detail to me. When his team arrived to do the work he ensured they knew what to do before he left. They did a great job and cleaned up after themselves. The whole experience was a professional and pleasant one. Many thanks to M Leon, I appreciate a reliable contractor for once, I have had so many not good experiences in the past. Melody read more

Excellent Work. Had the opportunity to have the M Leon Construction Company work on various jobs at my location twice. Both times they did quality work. They are very professional and offer great quality work at a reasonable price. I highly recommend this company for any work you might need. read more

Manuel Leon is one of the most well respected, honest and reliable construction managers I have ever dealt with. It is always a pleasure to do business with his company. He personally supervises the work of his crews and stands behind his work. I have always been satisfied with the work performed on drainage issues around my property, and I highly recommend this business. read more

We purchased our first home recently and it needed major foundation and construction work. M Leon was recommended by our realtor, and we liked the bid they worked up better than a competing bid...both in price and proposed solution. The things we loved about working with them include: 1. When the owner came out to the property to meet with us and talk us through the bid, he directed his questions/responses to me as much as to my husband. The home-buying process up to that point had included several inspectors and contractors who (never maliciously, but quite noticeably) addressed 100% of their communication to my spouse. I so appreciated that Manuel did not do that. 2. The crew was friendly, respectful, and cleaned up after themselves every day. 3. The work was finished within the time frame they set out, and within the budget set out in the bid (no small feat with such a major project). 4. Overall we just felt that Manuel and the crew understood what they were doing, had a lot of experience, and were prepared to address anything/everything that cropped up during the course of the project. The only reason I am giving them 4 stars instead of 5 has to do with communication, as it was occasionally difficult at times to receive a reply from the main office when trying to reach the team. I found it worked best to call, then follow up with an email, and then not be shy about following up again if needed. Toward the end of the project we happened to be home during the day when the crew was working and that was better, as Manuel stopped by at least once a day to check on the project, and talking with him in person works well. So my recommendation would be to try and arrange things so that you're home in person at the start and end of a major project. read more

Leon Construction did very good job on my craw space. They came on time. Perform outstanding job and cleanup the mess before leaving job site. Yes they don't have sale man with fancy uniform come out to give you a quote but they did give me a good price and did outstanding job. I called around 15 company to bid for a job, LEON construction gave me middle scale quote . I pick them due to their rate on yelp and I am not disappointed a bit. Good job Leon Construction and team who came out to my house to perform a job. I would use them again. read more

Our foundation needed major repairs and we also desperately needed a French drain in our side yard. M Leon was able to help us with both. They are communicative, courteous, and effective. We would definitely hire them again. read more

They excavated half of our basement that was all dirt and then put up retaining walls that extended to the foundation. After doing a lot of research, I chose M. Leon to do our foundation repair because they were recommended by several other contractors and they gave me the best price. Pascal and the workers were all lovely people and easy to have in and out of my house for three months. They resolved all of my concerns quickly and went above and beyond the scope of the contract on some of the details. Our neighbors had the exact same work being done on their house at the same time, and M.Leon finished our job at least a month ahead of them. I've already recommended them to another neighbor (we all have the same basement issues) and would recommend them to anyone who asked. They worked hard and did a great job. I'm very pleased with the outcome. read more

I was referred to this business by a commercial building contractor friend of mine. I called on a Monday morning and explained to the lady who answered the phone that I had a water leak in my crawlspace which had been hidden by insulation under the floor. I further stated that I had removed the insulation and found what appeared to be significant water damage to the subfloor and floor joists and wanted to find out if it would be ok after getting it dried out or if I would need to replace it all, and if replacement was needed, to get a bid on the job. She said they were getting a lot of calls and someone would call me back by the sometime the next day (Tuesday). When I hadn't heard anything by Friday, I called again. I explained that I had called on Monday but hadn't heard back. At first she said they had no record of my call, but with my persistance, she finally found a record of my call. She said someone would call me back shortly. Well, I wasn't holding my breath on that and set the phone down while I "used the facilities." Wouldn't you know, they pick those 2 minutes to call back. The message they left said that I lived too far away from their office and they don't do plumbing. They told me to call a plumber. So, why couldn't they have told me when I called the first time that they don't service my town? Why couldn't they have had the courtesy to call me on Tuesday, as they had promised, to tell me that. Also, I didn't call them to repair the plumbing. I called them for a job to repair/replace floor joists and several hundred square feet of floor & sub floor, possibly part of a load bearing wall...potentially, quite a costly job, not because I needed a plumber. So, I called right back only to be told the person was on another call. I asked for a call back when that call was completed. That was yesterday morning. It is after dinnertime now, the next day. I'm not holding my breath for that call back. All that said, my commercial contractor friend said this guy was the best crawl space guy around. I can't attest to that, but I can say that my experience as a potential customer was very disappointing, and in a way "you should call a plumber" they were insulting and dismissive. I won't be calling this company again. I wish you good luck if you decide to try them. read more

I have used Leon construction twice and have been very happy with them. Pascal knows his stuff and is very honest and reliable. last year they fixed the foundation and water issue in the crawl space. Today Pascal came and gave me advice on another issue I have in front of my house. I really appreciate his honesty and caring. I can fix the issue mysrlf with his advice. Thanks Pascal. read more

We had the crawlspace completely redone by this company and they did exceptional work. A year and a half later the house is being sold and the crawlspace is still in perfect order. Thank you Tito for going above and beyond to make the new Buyers happy. You and M. Leon Construction are top notch. The quality that this company does and at the modest price they charge is second to none. If I could give them 100 star rating, it's not enough. read more

Pascal's team took care of business and did a fantastic job! They helped talk us through a complicated project and and left a clean work space. Our job was tough to schedule, but they came through for us and we're able to get the project completed within our timeline. We are very grateful and would gladly work with them again! read more

M Leon was wonderful. They arrived on time, got the job done on schedule and on budget. Couldn't ask for more.

Update: I was initially not pleased with the service I received from M Leon Construction, but am impressed with the response I got after voicing my concerns. They care about doing a good job and the quality of the work was good. read more

In 2010 we purchased a 1960 home that was completely remodeled. The necessary repairs included replacing a number of posts and their cement pads under the house plus placing a new sump pump under the house to prevent a recurrence of rotting posts. Now ten years later I hadn't heard the pump switch off and on in a studio space located toward the back of the house and above the sump pump. (This may have been dryer than years past or I just wasn't in the studio as I had been in the past.) In any case, I called Leon Construction to come out and check the pump and make sure everything was in order. To our delight everything was working as it should. When I asked what the charge would be, "No Charge" was the answer. He was just happy that their was no malfunction and we could rest easy. How awesome is that!!! I highly recommend M Leon Construction. A job well done ten years ago and today for a follow up at my request. A+++ read more

Everyone at M. Leon construction is great. We had Tito install a sump pump for us almost 3 years ago and did a great job. We are selling our house now and needed them to come back out to check out something the inspector had pointed out that was wrong with the crawl space. They got out there as quick as possible, and re-sealed the vapour barrier for us no charge just to help us out as selling a house is stressful enough! Loraine was extremely helpful and accommodating. I would recommend them 100%!! read more

They are fast, reasonable and reputable. For many homeowners repairs like this comes when they are selling their home. M Leon will do the work so buyer's inspector can reinspect and are also offering to get paid at closing. Needless to say they will provide written warranty which is awesome. read more

I was really blown away by the professionalism, efficiency, thoroughness and support that I received in working with M Leon's team. From the day they gave me estimates to finishing the project, they did a great job of educating me on my options, explaining the work and making sure I was on board with their approach. They were incredibly efficient to get the project done and wrapped, even over the holidays, leaving my house and yard better than they found them. They also supported my choice to slightly build on their project and add in water collection to their drainage solution. I'd highly recommend them and will definitely use them for any and all future projects. Portland is lucky to have this company and professional team! read more

M Leon was called out by my realtor to follow-up on the inspection of the house we were considering purchasing, to evaluate the foundation and help us assess whether or not to go through with the purchase. They came, quickly examined the crawlspace and missed a MAJOR issue which is now costing us over 30K to repair. They failed to identify a major hole from a previously buried cesspool directly under the house. As we later found, when looking to put some insulation under the house, the hole was clearly visible from the crawlspace. Following M Leon's recommendation, we bought the house, and are now stuck with this massive expense and a lot of stress. read more

I highly recommend M Leon Construction to other real estate agents whenever there is a question about foundations or basement water problems. They are always prompt, concise in their bids, creative with solutions, offer flexible payment plans and have many years of experience. They offer all this without being pushy salespeople! Bravo! read more

We got a quote from several contractors to fix some water in a crawl space in a home we are purchasing, and M Leon was one of the quotes. They were by far the most thorough, and they didn't just look at the crawl space but reviewed the entire property to address the root cause of the water. Their quote was very competitive and offered a better solution than any other bid we received. They were extremely helpful and communicated every step of the way. Once the work began Christine, the project manager, met me at the property and touched base with me every day to let me know how the project was progressing. We had a few unforeseen issues along the way and M Leon went above and beyond to ensure everything was taken care of, even items not in the original bid! Their entire team is very knowledgeable and great to work with. The owner even came out one day just to check on the project. They will be my go to contractor from now on! read more

Great, professional guys, experts at basement upgrades and they do amazing things with concrete. Recommended to me by my real estate agent and very glad to have met them! I had M. Leon Construction do some serious updates to my basement. Pascal came and estimated the job, talked me through it in great detail with great patience, sent a fixed bid with options to do more now or save some for later (a really big plus), and then came with a crew of two to perform the work. They worked steadily and quickly, having done dozens or maybe hundreds of these kind of jobs, and the results now look fantastic both inside and out. No mess was left. During construction we ran into several unforeseen and hidden problems - mostly rotten out beams that were concealed before. When this happened we stopped to evaluate our options and I was given an update as to the additional costs. Pascal kept these additional costs down, which I greatly appreciated. Other than this, the team stuck to the original fixed bid covering both labor and materials. There were even instances where the team saw an easy opportunity to add on a little extra and they did - for example, covering a small patch of exposed dirt with concrete rather than plastic sheeting. All in all, it was a pleasure working with M. Leon. Everyone on the team was very easy to talk to and great at explaining things, including letting me know what additional repairs I could do myself and how to do them correctly (awesome!). The work was performed professionally, quickly, and expertly. It's hard to know but I believe the price was fair considering the big size of the project and the clean look that resulted. Thanks M. Leon! read more

Excellent company who stand by their work. I am a real estate broker and highly recommend them to my clients who need any drainage or crawlspace work. They never fail to do a fantastic job and solve the problem. I can't recommend them enough. read more

Had Crawlspace cleaned up after 25 years in home. This involved repairing insulations where it had dropped down, removing old ductwork that had been previously replaced, and re-lining the whole vapor barrier. They also went around the outside of my house and made sure that all the air vents were clear and had screens. They were quick to respond to my initial request, and easy to work with on scheduling. All the people I met and worked with were nice and courteous, and the work crew was efficient and made sure that the work area was protected and they left it clean. read more

M. Leon was recommended by our realtor. He came to give me a bid for work on my basement. He was right on time for the appointment and even took his shoes off to come into the house, without being asked to. He was friendly and knowledgeable. He gave a comprehensive report on what needed to be done. read more

I called to get our crawl space checked, they came out fast (Tito was the guy who was nice and thoroughly checked). thank you

Surprised at the glowing reviews. I paid an exorbitant amount for drainage and crawlspace work. The bid including a vapor barrier. I was shocked at their results. I have seen proper vapor barriers installed with seams going up the wall at least several inches. In this case, they simply laid down cheap plastic with no work done on the side walls. They were supposed to close all entries (to prevent rodents, etc) in the basement and that was not done. To make matters worse, the debris (old carpets left by previous owners) that was paid for in the bid to remove, was thrown over the decks and left to decompose in our backyard green space. Our terrible realtor recommended them and I'm so very sorry to have had them do the work. read more

M. Leon is a consummate professional. He instills trust and is a truly competent craftsman who demands the utmost quality from his team. He uses quality materials and employs skilled trades. From the time of the bid, to the completion of our very complicated project, we had excellent communication throughout. M. Leon provided an objective, empirical approach to solving our drainage needs, based upon over 35 years of experience. He was patient, answered multiple questions (we are both engineers) and provided sound engineering solutions without unnecessary inefficiencies or add ons. He minimized the impact to us, the homeowners, with care to protect our historical home, treating it as if it was his own. In the end, he established a sound solution, sound judgement and peace of mind. He met and exceeded our very high standards, with his knowledge, competence, professionalism and customer orientation. If you have water issues in the NW hills and want them eliminated - do yourself a huge favor and immediately call M. Leon Construction. You may pay a little more, but it is well worth it. He will resolve your problem and even remedy any shoddy work done previously (FYI for our home, he totally resolved an inadequate job performed by another local, "waterproofing" firm - hired by the prior home owners, who opted for a cheap "fix"). Do the job right. Do it well. Hire M. Leon. read more

I was charged over $5000 to do outside drainage around my house, but there is still water under the house, now they want another $2000 to finish what the $5000 should have. Nope read more

This company was hired to fix the water issues in the crawl space of the house we bought prior to our purchase. We have a warranty and noticed standing water. They came out and took a look, said it needs additional french drains and would get us scheduled. That was over two months ago and have had no luck getting them to come back to do the work. Convenient that our warranty will be up before it really starts raining again. Very unprofessional. Guess I will need to file a formal complaint to get this resolved. read more
