For winter drafts coming through your front door, a fiberglass entry door usually outperforms an older wood 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. Many homeowners love their wood door, yet its material shifts with the weather, bringing frequent repainting and rot from moisture damage.
What Homeowners Need to Know:
- Warp factor: Old wood doors swell and shrink with the seasons, which widens the gaps behind front door drafts.
- Steady shape: Fiberglass resists warping, so it keeps a tighter seal when you winterize your home. See entry door options to compare.
- Seal limits: Many homeowners look up how to install door weatherstripping, but a worn wood door soon drafts again.
- Fiberglass cost: A grand fiberglass entry door averages $11,953 and returns about 87% of cost.
- Steel compare: A steel entry door averages $2,547 and returns about 216% of project cost.
- Certified savings: ENERGY STAR certified doors can trim heating and cooling costs by up to 13% on average.
