ARE YOUR WINDOWS & DOORS COSTING YOU COMFORT & MONEY?
Old or damaged windows and doors can lead to drafts, higher energy bills, moisture issues, and reduced curb appeal. At Capital Roofing and Exteriors, we install high-quality replacement windows designed to improve efficiency, comfort, and long-term protection.
Two trades, one crew
What are you looking to replace?
We install and repair both, with our own crews. Pick the one you need and we will walk you through the styles we carry, whether a repair or a replacement is the honest answer, and how storm damage claims work.

REAL WINDOW TRANSFORMATION — SEE THE DIFFERENCE
From Drafty, Outdated Windows to a Comfortable, More Efficient Home
New windows can improve curb appeal, comfort, and energy efficiency while helping protect your home from leaks, drafts, and aging materials.  At Capital Roofing and Exteriors, we install quality replacement windows  with clean workmanship, honest recommendations, and options built around your home’s needs.
OUT WITH THE OLD & IN WITH THE NEW
Replacing old, inefficient windows with high-energy-efficient windows is a smart way to improve your home’s comfort and save money. New windows help reduce heat loss in the winter and keep unwanted heat out during the summer, making it easier for your heating and cooling systems to maintain a comfortable temperature. This can lower energy bills, improve indoor comfort, reduce drafts, and increase the overall value of your home.
Our door work
Doors, not just windows
The same crews that set your windows hang your doors. Below is a recent job in Southern Maryland — a weathered aluminum slider replaced with a black French double-door unit, with the trim rebuilt and a new threshold set and sealed.

Protecting the wood before it rots
Wood trim around basement doors and windows takes a beating from ground-level moisture, splash-back, and years of freeze-thaw cycles. Once the paint seal breaks, bare wood starts soaking up water and rot sets in fast, often hidden until the trim is soft or crumbling. Wrapping exposed wood trim in aluminum coil stock creates a permanent, weatherproof barrier that locks moisture out for good, cuts out the yearly repainting and caulking, and protects the structural wood underneath so it doesn’t have to be replaced down the road. It’s a small upgrade now that prevents a much bigger repair later.
