Friendly and the finished product is good. They are fairly quick and have a good stucco patch guy. Would work with Lema again.

We had a great experience and highly recommend Lema Windows and Doors! Very responsive and we were pleased with the quality. We will definitely use them again in the future future. read more

I had Lema Windows pull out a window to replace it with a door. The door is great quality. The price was very reasonable and the work done exceptionally well in one day. Communication throughout the process was very good and no surprises anywhere. Will definitely have them come back when I change out my slider. read more

Lema Windows and Doors - Windows Installation Near Me - Concord, California

Lema Windows and Doors did a great job on our family home. They were very responsive. Leszek communicated everything about the project clearly, answered all of our questions with great detail, and provided the best advice. We originally contacted them about a patio slider and they provided the best quote, focusing on quality and what we wanted, and service. We asked them for additional help with another project that we were doing ourselves. They helped us resolve the issues we had with a different leaking window and door. They caught several problems with the advice and plans we'd been given, which saved us from long-term issues, so we ended up expanding the scope from just the patio to a door and window with them. We got the look we wanted, the safety we wanted, and it was all installed so quickly and professionally. The stucco work looks perfect and was also done very professionally. We will definitely use them for any future work on the house. Highly recommend. read more

Fast, efficient, and reasonably priced! They installed two windows for me and were very quick to respond!

I basically got ghosted. I was calling around to get quotes and info on patio doors. He answers the phone to have a quick convo and then moved the rest to text. But after a couple of days I stopped getting answers. Weird that he didn't offer to come do a measure or in-person quote too. It felt too casual. read more

I had time set aside out of my day, they came over took measurements, never called me back or gave me a quote. If they say this is fake (like one other review they called "fake"), this is not, I have time stamps to prove it. Safe to say communicatation isn't great with them. They have a bad habit of not following up on what they say. read more

We got multiple quotes to replace both our back patio doors and Lema came in at the best price and Leszek was very responsive without being a pushy. We are very happy with the work, and the stucco repair work was great. you wouldn't know that any repair work had been done which we learned can sometimes happen with bad stucco repair. We will definitely reach out to Lema when we need to have other door and window work done. read more

Had a great experience with replacing my windows. The installation itself was easy and professional. The crew showed up on time, cleaned up after themselves, and treated my home with care. New windows were perfect. If you're in the East Bay and thinking about replacing your windows, Lema was awesome. read more

Good quality work. They removed a window, enlarged the opening and installed a patio door in its place, moving electrical outlets. The job was quickly done in less than a day, and they cleaned up so well that you could not tell anyone was there (except for the new patio door, of course). Their pricing was the best bang for the buck I could find. read more

I've been using Lema Window and Door for over 10 years now, and their quality is impeccable, deliver on every project, take pride in their work, and very efficient with their time and competitive in pricing. Highly recommend! read more

We just had Lema windows and doors replaced our bay windows. The whole install process was smooth and clean and very pay attention to every detail which was beyond my expectation, honestly. They not only replaced the windows but also rebuilt the whole bay window systems and I didn't know how complicated was that but they did a GREAT job! The communication was great and the quote is reasonable and fair! Highly recommended and will go to them for more window projects for sure! read more

Had him come out for a quote for some windows and a door. Promised a quote and got ghosted.

The owner came out to the job site and looked over the property within a day of being contacted. I got a quote the next day, and a signed contract a few days later. Work was completed rapidly (1 day for 2 doors and 5 windows), and the staff were professional and courteous. I can highly recommend this company for not only the price, but also the responsiveness of the managing staff. read more

We had an external garage door that they needed to be replaced. We are so happy with our door and painting job and would no hesitate to recommend Lema! Leszek was so good with communication and really provides excellent service! Glad we found him! read more

Lema Construction just finished replacing 38 windows and a French door in my home. My job was complicated and included a lot of detailed stucco repair. You cannot even tell the work has been done. Leszek and his crew were fantastic. During the job I had another problem in my home. Leszek immediately stepped in and managed those repairs for me as well. Leszek and his crew were efficient, professional, competitively priced and friendly. They took great care of my property and completed the project within the timeframe promised. I highly recommend Lema Construction for your next home renovation. read more

We just got a new front door put in and it was a great experience. Leszek and his team were fast, courteous, cleaned up after themselves and did everything when they said they would. Sometimes he can be tough to track down because of how busy they are, but his prices and service made that a non issue. Highly recommend. read more

I originally had a bad experience with a different company who came out and took measurements, but never got back to me. I then found this company and I'm so happy I did. The owner came out, took measurements and emailed a quote that was easy to read and follow. Once the windows and doors came in, he let us know when the work would start. It was a smooth and easy process. The price never changed and the owner, Leshek came back when I wasn't satisfied. I would absolutely recommend this company and even asked them to come back and change some more windows. They do excellent work!! Added plus; even my 12 year old dog Bean likes him. Lol! read more

So it's been about six months and the new door got slightly out of adjustment. Leszek and helper came by and fixed it, and another door besides. No charge! And no reason to call anyone else for doors and windows. read more

Just hire Lema. Leszek has done a few window projects for us to date, and we've been impressed every time with his professionalism, efficiency, and quality of his work. He and his crew replaced all of the sliding windows in our home over three years ago, and I couldn't believe that they were able to knock out the whole project in one day. The windows have never leaked, and are still functioning well and as intended to this day. If you want someone who genuinely has your best interests at heart, and who will show up with a positive/can-do attitude, Leszek is your guy. read more

They recently installed all new windows in our home. They look amazing! ONly took about 3 weeks for windows to arrive and took 2 days to install. The crew was great, very respectful, on time, and clean. High recommend!! read more

Leszek was referred to me by a couple of friends. I reached out to him to get a quote on replacing the windows and slider at my condo. He stopped by the next morning and had a quote to me within a couple of hours. I've had probably 10 different quotes over the last couple of years and this was the first time I felt zero pressure to immediately say 'yes' on the spot. His pricing was extremely reasonable and he was great to work with. Fast forward 4 weeks and my new windows were installed in one afternoon. His team was in and out in no time, with no evidence that they were even there (besides my pretty new windows!) If you're looking for someone you can trust to get the job done right and make the process as easy as possible Leszek is your guy! read more

We had Lema replace our basement door. They were absolutely awesome! Very friendly, fast, communicative, and professional. And as a woman, I felt completely comfortable with everyone who came out to the house (Leszek to give an estimate and his two team members to do the installation). I feel so grateful for this experience and we will definitely call them again for our front door replacement. read more

I am very pleased with the work Lema Construction did for me. They replaced all of the windows in the second story of my home. When we had an emergency with the kitchen windows, he came out, measured and ordered the replacements. The entire crew was prompt, efficient and did a fantastic job at a reasonable price. read more

Leszek is a great, no BS contractor that will give you the fairest bid around. His team is very efficient and fast working and do quality work. He saved me a small fortune from Renewal by Andersen. read more

I was truly impressed with the new windows, both inside and out. They do an excellent job of keeping external noise to a minimum. The installation on July 10th exceeded my expectations. Derick and his crew worked efficiently, and I was delighted by the two young assistants who skillfully carried the heavy windows up to the second and third floors of our townhouse, taking care not to damage the walls or hanging lamps. Plus, they disposed all of the old window frames, which was a huge relief for us. They kept the work area tidy and left the windows looking shiny and spotless. They were all very approachable and easy to talk to as well. I highly recommend Lema Windows. read more

Fantastic company. Delivered as promised and did a very high-quality job in one of my properties. I definitely plan to use them on future projects and highly recommend the company. Leszek was very professional and friendly to work with. K. R. Kieffer read more

Highly recommend Lema Windows and Doors. The owner, Leszak, is a pleasure to work with. He is professional and knows what he is doing. Not only is he taking the measurements and doing the quotes, he is installing the product too. In every project there are always questions that a homeowner needs to answer and sometimes it can be confusing. Leszak is right there helping you make a good decision and I really appreciated that. We redid all of our windows and doors in our backyard and will do the front of the house after we recuperate from our backyard remodel. We also changed windows to doors for more access to the backyard. This was not a problem for Leszak and his crew. The windows/doors took about 6 months to ship, but that had nothing to do with Lema and all to do with current state of the world. Thanks Leszak for a great job! read more

Finding someone dependable in the construction trade who does good work at a fair price has become extremely challenging. Lema Windows & Doors is my go to for anything related to windows and doors. They were responsive, prompt, affordable and did amazing work. I first hired them to replace my front door. It was a challenging job and all the other bids were crazy high for no apparent reason. Leszek was on top of everything and followed up to even make sure that I was happy with the work that his stucco subcontractor did (which I was) after the door was installed. A few years later I hired them to install a garden window. Another amazing job well done. read more
