The best upgrade for drafts coming through your front door is an insulated steel or fiberglass entry door. 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. Fresh sealing helps first, but a new door delivers lasting comfort through the winter.
What Homeowners Need to Know:
- Seal first: Fresh weatherstripping and a snug door sweep stop most drafts coming through your front door. Start here to winterize your home.
- Short-term limits: Many homeowners search how to install door weatherstripping, but a fresh seal lasts only a year or two.
- Foam core: A foam core inside steel and fiberglass doors adds insulation, a smarter long-term fix than sealing alone.
- Steel value: A steel entry door averages $2,547 and returns about 216% of project cost.
- Fiberglass option: A grand fiberglass entry door averages $11,953 and returns about 87%.
- Certified savings: ENERGY STAR certified doors can trim heating and cooling costs by up to 13% on average.
