Stop losing heat in winter and AC in summer.
Drafty windows and doors don't just cost you in January — they leak your AC in July, when energy is even more expensive. Whether you just moved in or have lived here for years, most homeowners replace too much. We show you what actually needs fixing — first.
- We find the problem before recommending fixes
- Replace only what actually needs replacing
- Designed for New England weather — winter and summer

Frequently asked questions
Straight answers about the Home Efficiency Check and our work across MA, NH, ME & RI.
Do I always need to replace my windows?
No. Most homes we assess do not need full replacement. If a window only needs sealing or a single sash, we will tell you. Our Home Efficiency Check is designed to find the actual loss points first, so you only replace what truly needs replacing.
How long does the Home Efficiency Check take?
About 10 minutes on-site. We walk your home, identify where you are losing heat in winter and AC in summer, and show you what actually needs fixing.
Is the Home Efficiency Check really free?
Yes. The Home Efficiency Check is free and carries no obligation. You will get clarity on what to fix, not a sales pitch.
What areas does Seaside Windows & Doors serve?
We serve homeowners across Massachusetts, New Hampshire, Maine, and Rhode Island, with a focus on coastal New England weather conditions.
Do drafty windows cost more in summer or winter?
Both, but summer cooling is often more expensive per kilowatt-hour than winter heating in New England. Drafty windows and doors leak conditioned air year-round, which is why an efficiency check pays off in both seasons.
What types of doors does Seaside install?
We install entry doors, patio doors, and storm doors — all with weather-tight seals built for New England winters and humid summers.
