My husband and I met with Pat Jewell and he was such a pleasure to work with. Very knowledgeable and kind. We felt comfortable with this company.
We are very pleased with the work that Capitol Improvements did and we would highly recommend and use them again in the future.

They had the most competitive prices and did not try and upsell. Their teams are efficient, professional, very clean, and on time.

Seth and install team were organized and project went smoothly. Entire team was responsive and kept in touch throughout the process.
They replaced my roof including skylights in April 2023 and I am very satisfied. Melinda as my first contact was very professional and got me on the schedule quickly.
It was easy to work with Pat to get a quote. We did both a roof on our house and our shed, we also had new gutters put on our den. The crew was very hardworking and efficient.
