Coastal Windows & Exteriors handles both window and siding replacement under one contract. A woman-owned exterior remodeling company serving 730+ towns across Massachusetts, New Hampshire and Maine, Coastal Windows & Exteriors has completed 7,000+ installations since 2011, and pairing both projects in one window and siding replacement seals the wall envelope at once.

Why Pairing These Projects Pays Off

One sealed envelope: Windows and walls meet at flashing points. A single crew handles both sides of that connection with no finger pointing.
Air tightness gains: Insulated siding can improve a home’s air tightness by an average of 25%. Comfort improvements are possible with professional installation.
Under-insulated reality: 89% of U.S. homes fall short on insulation. Addressing walls and windows together closes the biggest gaps at once.
Energy bill relief: Massachusetts households spend roughly $600 monthly on energy. Tighter walls may lower those costs over time.
Cleaner trim details: New capping and trim install once, not twice. Your finished exterior looks intentional from every angle.
Single point of contact: One project manager, one schedule, one warranty conversation. Coordination headaches disappear from your calendar.

Building the Right Project Bundle

Top Recommendation: Windows and insulated siding together for the tightest wall assembly possible.
Great for Budget: Phase the work, starting with the elevation showing the most wear.
Ideal for Comfort: Foam-back siding paired with new windows on your coldest exposure.
