Miguel did a great job on our roof and gutter installation. Even on a hot DC day, Miguel was able to get the whole project complete in one day. We have no complaints with Miguel! We did find Pat to be challenging to work with. He would be insist on talking later in the evening, and would take days to respond to…
I had a full roof replacement done by Capitol Improvements, and the entire experience exceeded my expectations. The quality of their work is outstanding. You can tell they take pride in what they do. They’re a family-run company, which made the whole process feel more personal and trustworthy. I worked directly…
Excellent work! Very professional team from start to finish!
Great team, easy to work with remotely and very professional. Repairs were fast and completed on time.
Excellent work! Did have a small gap however they came the same day and repaired the issue. Highly recommended!!!
They did a great job! Very responsive and knowledgeable! Installed my roof and gutters. Lance and Seth were both wonderful to work with!
Everyone on this team is awesome! They were very patient with me as I had received a grant from the MD government.. Melissa was especially helpful, just when I was going give up she helped me push though and I got the help needed for getting a new roof I needed. I love they customer service I will very much use them…
I had a wonderful experience with the company. They help me through my insurance. They did a very good job. I Wood recommend them to everyone.
Lance and the team were great. We replaced the entire roof and it was completed professionally and efficiently over a two day span. With the harsh storms we’ve been having, I have peace of mind knowing that there will be no leaking inside of the house.
