..I would like to thank you for how beautiful you have made my house look. I finally have my dream kitchen. We called you back a second time to build our 2-bedroom and bathroom addition, which gave us plenty of extra room for everyone in our home. We are very happy with all of your work and your employees. Everything was done to my expectations and in a timely manner. My neighbors all compliment on the way the house looks from the work that you have done. I couldn’t thank you enough.” — Evelyn B., Newark, DE

This is Frank’s forté. When planning an addition, tying the roof into the existing structure is the most important part of the job. We can install any type of roofing material–from a rubber roof for commercial buildings to the most complex roofing systems for residential applications…

Frank Devonshire General Contracting will plan your addition from the ground up. We can do it all – Architecture, digging of the footers, foundation, roofing and more!

With all the latest brands of cabinets, fixtures and flooring our team will give your new kitchen the beauty of “Jim Bishop” Cabinets, the reliability of Moen Fixtures and durability of Ziggy Flooring products.
