Keith was so kind, and very responsive to my call. I was sheduled for service right away, and he was able to fix my screen door in no time. He answered every question with grace... and I had so many questions!! We had good conversation while he worked, and I learned so much from him. I highly recommend and will definitely use them again.

I used Maryland Windows Doors and Roofs to replace windows and a patio door. Thom their Sales Representative was very knowledgeable and helpful in selecting the products we ultimately chose. He actually called and kept us up to date during the process (something unheard of these days). The installers were very professional and performed an excellent job. I would use them again and would recommend them to anyone. Thanks again to Maryland Window Doors and Roofs!

The siding on the back of my house came off during a heavy windstorm. So, I called someone I trusted to respond quickly and do a quality job at a fair price. I have worked with Keith before. He installed a new roof and on another occasion he installed new gutters. Once again, I couldn't be more satisfied with the response and the work.

Great experience. I had to get a sliding glass door replaced. I was quickly given a quote that was competitive with other contractors. They ordered the door immediately, but in COVID times there was a delay in delivery. The great thing was the communication, keeping me informed of the status. The door was installed today. I was not able to be there , but Thom was on-site with the installers (wearing masks) and sent me pics of the progress. Great company, highly recommend!

I found the team at Maryland Windows Doors Roofs to be incredibly professional. Tom, who performed the initial consultation, was very courteous and professional. He helped identify the perfect front door replacement for our house. He informed us that the door was ready much earlier than we expected. The installation team was friendly and responsive to questions and careful with their installation. At the end of the day, it looked absolutely marvelous and we are so happy with the result. I would recommend Maryland Windows Doors Roofs to anyone!

We worked with Maryland Windows Doors Roofs to fix our roof prior to installing solar panels. Keith and his team were incredibly patient in explaining our options and talking us through the best choices for us and our house. The workers were conscientious, timely, and professional. When a different part of the roof (that they did not work on) started leaking, they came back several times to first ensure it wasn't their fault and then second to recommend solutions. When it came time to fix that part of the roof, we did not hesitate to work with them again. If you are looking for a professional roofing job at a good value, I could not recommend this company more highly.

We contacted Keith about replacing our home's roof after 20 years. Keith was very responsive, professional and truly a pleasure to work with. The proposal was first class and at an extremely competitive price. We worked together to schedule the removal/installation at a time that worked for us while facing shortening days, the holiday season and a pandemic. His team worked diligently to complete all the work in one day with our relatively complicated job of a main roof, garage, porch, screen porch and shed. They came very close, but had to come out the next day to finish the installation ahead of a projected snowfall. I was further impressed with Keith's professionalism when he did not accept final payment until the job was complete and cleaned up to our satisfaction. You can be very confident working with Maryland Windows Doors Roofs.

This company delivers a high quality product. He really knows his business and offers excellent advice. We've invited this company back for multiple jobs from doors to our roof to siding. I would recommend this company to anyone looking for professional renovations on their home.
