Water leaking around your exterior door in heavy rain usually starts with worn weatherstripping or a failed seal, and while new weatherstripping helps, it cannot cure a warped or aging door — when leaks keep returning, replacing the door is the best answer for lasting protection. Coastal Windows & Exteriors is a woman-owned exterior remodeling company with 7,000+ installations completed since 2011, serving 730+ towns across Massachusetts, New Hampshire and Maine.

What New England Homeowners Need to Know:

Seal check first: Worn door weatherstripping is the first thing to check when rain gets in. Book a free estimate for a look.
Trace the draft: A returning exterior door draft often points to a failed seal or warped frame. Weather protection ranks high for 61% of door pros.
Beyond a reseal: A door seal replacement helps briefly, but recurring leaks signal a new door.
Steel value: A steel entry door averages $2,547 in New England and returns about 216% of cost. See these entry door warning signs.
Efficiency gain: ENERGY STAR certified doors can trim heating and cooling bills up to 13%.

Cause	Sign	Best Fix
Worn weatherstripping	Drafts and minor water at the edges	Reseal, a short-term fix
Failed threshold or seal	Water pooling at the base	Reseal or adjust
Warped or aging door	Recurring leaks despite resealing	Replace the door

Making the Best Choice for Your Home

Top Recommendation: A professional inspection, then a door replacement if resealing no longer holds. Book a free estimate with Coastal for a free assessment!

Best for minor drafts: Fresh weatherstripping or a threshold adjustment when the door is still sound.

Smart for recurring leaks: A new steel or fiberglass entry door for a lasting, weathertight seal.
