A woman-owned exterior remodeling company with 7,000+ installations completed since 2011, Coastal Windows & Exteriors serves 730+ towns across Massachusetts, New Hampshire and Maine.
Why Homeowners Combine Both Projects
- One Crew, One Schedule — Handling siding and windows together means a single mobilization. You live through one project window rather than two separate ones.
- Flashing Details Get Done Right — New windows integrate cleanly with new house wrap and trim. Separate projects often leave seams that leak years later.
- Air Sealing Compounds the Benefit — Insulated siding can improve a home’s air tightness by an average of 25%. Pairing that with new windows tightens the whole envelope.
- Under-Insulation Is the Norm — 89% of homes are under-insulated. Combined vinyl siding replacement and window work addresses that gap head-on.
- Energy Bills Deserve Attention — Households spend real money on heating each month. Savings are possible with professional installation of both systems.
- One Warranty Conversation — Bundled work keeps accountability with a single company. Nobody points fingers when questions come up later.
