Before & After
Real Window Transformation: See the Difference
From drafty, outdated windows to a comfortable, more efficient home.



Clean Workmanship
From Drafty & Outdated to Comfortable & Efficient
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.
- Double-hung & casement
- Sliders, bay & bow
- Picture windows
- Basement & egress

Energy Efficiency
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.
- Lower energy bills
- Better indoor comfort
- Fewer drafts
- Higher home value
Warning Signs
Signs It’s Time to Replace
If you notice any of these, a free estimate can tell you whether a repair or a replacement is the honest answer.
Drafts & Cold Spots
Air leaking around sashes and frames makes rooms uncomfortable and your HVAC work harder.
Foggy Glass
Condensation between panes means the seal has failed and the insulating gas is gone.
Hard to Open or Lock
Sticking sashes, worn rollers, and broken hardware are safety and security problems.
Leaks & Water Stains
Water around frames can rot trim and framing behind the walls.
Rising Energy Bills
Old single-pane or failing windows let heated and cooled air escape.
Storm Damage
Cracked glass and damaged frames from storms may be covered. We can help with claims.
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.


Basement door wrap
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.
