Window replacement in Wenham, Massachusetts swaps existing windows in existing openings (distinct from window installation which creates new openings). Two replacement methods: insert replacement (new window fits inside existing frame, faster + lower cost $650-$1,400 per window) and full-frame replacement (existing frame removed entirely, more expensive + better long-term $1,200-$2,500 per window). Pro Build holds Massachusetts CSL + Home Improvement Contractor licenses.
How Insert vs Full-Frame Differs
Window replacement in Wenham drives three critical decisions:
- Insert vs full-frame replacement. Insert: new window fits inside existing frame — fastest, lowest cost ($650-$1,400/window), preserves interior trim. Full-frame: existing frame removed entirely — more expensive ($1,200-$2,500/window), addresses rot/water damage, allows larger glass area.
- Energy Star Northern Climate compliance. MA stretch code requires U-factor 0.27 or lower. Existing 1980s windows often U-factor 0.50+ — major upgrade opportunity. Premium replacements (Andersen 400, Marvin Essential, Pella Lifestyle) easily meet code; triple-pane available for 6A.
- Whole-home vs phased replacement. Whole-home 10-25 window project: $8,500-$50,000+ (volume discount typical). Phased replacement (worst windows first): higher per-window cost but spreads investment. Pro Build evaluates ROI per window during assessment.
North Shore window replacements face coastal-grade hurricane-rated windows + replacing salt-air-degraded existing units.

What Sets Pro Build Apart
Most Wenham window replacement contractors push insert replacement (faster + cheaper for them) regardless of frame condition. Pro Build evaluates honestly + recommends full-frame when needed.
- Honest insert vs full-frame recommendation. Frame rot or water damage = full-frame; sound frame = insert.
- Manufacturer-authorized installer. Andersen + Marvin + Pella + Harvey authorized status preserves warranties.
- Energy Star flashing expertise. Proper flashing prevents water infiltration over 20-year window life.
- Whole-home volume pricing. 10-20% discount on 10+ window projects.
- Three in-house licenses. CSL + HIC + Master Electrician (for any electrical relocations during full-frame).
- 5-year workmanship + 20-year manufacturer warranty in writing.
Six reasons compound. Honest insert vs full-frame recommendation alone is the difference between covering existing damage vs addressing it properly.
