Living in a historical city like Gaithersburg can have its challenges on your house and property. Buildings that were constructed over a hundred or even two hundred years ago can be susceptible to different sorts of problems than newer constructions. And although further inland than other cities in Maryland, Gaithersburg is still very much impacted by coastal storms that come off the Atlantic Ocean. These two factors make it very important to pay attention to things like your roof, siding, gutters, and windows, making sure to have them updated when necessary.

Neglecting to change your windows or redo your roof when wear is beginning to be noticeable will lead to larger problems done the road such as leaks, mildew, or mold issues, as well as a lack of efficiency from cold air getting in during the winter leading to larger heating bills.

Reviews of Gaithersburg Roofing and Siding Contractor Capitol Improvements

⭐ ⭐ ⭐ ⭐ ⭐
“We got a referral from a neighbor for Capital Improvements. It was easy to work with Pat to get a quote. We did both a roof on our house and on our shed, and then we also had new gutters put on our den. The crew was very hardworking and efficient. And they did a great job of cleaning up…. The gutters were installed in only a couple of hours about 3 weeks after the roof was put on. It was great to work with this team and we know we got a really good product. Highly recommend!” -Ariana S.G. (Google Review)
