Window Replacement

Drafty windows? We'll fix that fast.

Window Replacement

Replacing old, drafty, or failed windows is one of the best investments a New Hampshire homeowner can make. We remove your existing windows, inspect the surrounding structure, and install new units with proper insulation and weatherproofing — so you stay warm in winter and cool in summer.

  • Structural inspection included with every job
  • Proper insulation and air sealing throughout
  • Minimal disruption — most jobs done in a single day

Window replacement typically runs $650–$1000 per window installed. Multi-window discounts available.

Door Installation

We carry fiberglass, steel, and wood options to match any architectural style.

  • Fiberglass, steel, and solid wood options
  • Deadbolt and hardware installation included

Old door sticking, drafty, or just outdated?

If your existing door is warped, drafty, or simply past its prime, we'll remove it and install a new one that fits perfectly and seals tight. We handle all door types — including sliding patio doors, French doors, and storm doors — and leave the job site clean when we're done.

  • Like-for-like replacement or upgrade to a new style
