Window Installation Properly fitted, weatherproof, energy-efficient — built for MA winters.

Cost varies widely based on window count, brand, frame material, glass package, and replacement vs new construction approach. Builder-grade vinyl windows are the most affordable. Premium Andersen A-Series, Marvin Signature, and Pella Architect Series are top tier. Mass Save rebates can reduce net cost on qualifying Energy Star installations. Written estimates after on-site measure visit.

Single window replacement: 1-2 hours. Small project (4-6 windows): 1 day. Average home (12-18 windows): 2-3 days. Full house with new construction approach: 3-5 days. The 4-8 week wait is in window manufacturing — once windows arrive, install is quick.

Replacement (insert) windows install into existing frame — trim and siding stay in place. Faster, cheaper, but glass area is slightly smaller. Requires existing frame in good condition. New construction (full frame) replaces the entire window including frame and flashing. More labor and trim work, but solves rotted frame issues and provides full glass area. We assess your existing frames and recommend the right approach per window.

Andersen (400 Series, A-Series), Marvin (Elevate, Signature, Ultimate), Pella (Lifestyle, Impervia, Architect Series), Harvey (Tribute, Classic), and others. Each brand has tiers from mid-range to premium. We can install any major brand — recommend based on your home, budget, and aesthetic preferences during the estimate visit.

Energy Star Northern Climate Zone certified windows are standard for MA installations. This certification requires U-factor ≤0.30 (lower = better insulation), specific SHGC ratings, and verified NFRC ratings. These windows qualify for Mass Save rebates and federal energy efficiency tax credits when available.

Mass Save is Massachusetts’ utility-funded energy efficiency program. Qualifying Energy Star window installations may qualify for rebates of $50-$200+ per window depending on current program offerings (program details change year to year). We handle the rebate paperwork as part of the installation. Rebate is paid by check after installation completion and submission. The rebate is on top of your reduced heating bills going forward.

Yes — MA building code R310 requires emergency escape and rescue openings in every basement bedroom and any sleeping room. Minimum dimensions: 5.7 sq ft opening area, 24″ minimum height, 20″ minimum width, and 44″ max sill height from floor. If converting basement to bedroom, egress is non-negotiable. We size egress windows correctly and coordinate any necessary wall framing changes.

Window replacement on pre-1978 homes requires EPA RRP lead-safe practices because window trim disturbance creates lead paint dust. We follow proper containment (plastic sheeting, HEPA vacuums), use lead-safe scraping practices, and dispose of debris correctly. Required by federal law. Also required by MA 105 CMR 460.000 lead-safe renovation rules.

For replacement (insert) installations, yes — interior and exterior trim stays in place. For new construction (full frame) installations, trim is removed and reinstalled or replaced. If your trim is in good condition with the right profile, we can usually save and reinstall it. If trim is damaged or you want updated trim styles, replacement is recommended.
