Replace drafty windows before winter when resealing no longer holds and heating bills keep climbing. A woman-owned, family-run remodeler founded in 2011 (not a franchise), Coastal Windows & Exteriors has completed 7,000+ installations across 730+ towns in Massachusetts, New Hampshire and Maine. Small gaps sometimes seal well, so an honest assessment comes first—but foggy glass and failed seals signal that replacement, not another patch, protects comfort and savings.
What Homeowners Need to Know
- Reseal limits: Resealing helps small gaps, yet fogged glass and warped frames mean drafty windows need replacing. Book a free estimate for an honest assessment.
- Bill context: Massachusetts households spend roughly $600 a month on energy bills, and leaks push that higher. Rising costs often signal failing windows.
- Surface share: Windows cover about 8% of a home’s exterior, yet drive much of winter heat loss. Small area, big impact.
- Energy upgrade: Upgrading from single to triple pane windows saves over $500 a year on energy bills. Efficient glass steadies indoor comfort.
- Resale value: Window replacement returns about 76% of project cost, so winter upgrades pay you back. Replacement also solves the old-window problems that quietly raise winter heating bills.
- Whole envelope: To winterize your home, pair new windows with sealed doors and added attic insulation. Windows alone rarely fix every draft.
| Option | Pros | Cons | Best For | Price |
|---|---|---|---|---|
| Reseal | Low upfront cost, fast | Temporary, fails on fogged glass | Minor gaps, newer windows | Hundreds |
| Replace | Ends drafts, about 76% ROI, lower bills | Higher upfront cost | Old, fogged, or failed windows | Estimated national average about $21,922 |
