What we do

Our Services

Quality replacement windows, entry doors, and patio doors — installed right, priced honestly. No corporate markups, no upsells.

Replacement Windows

Drafty windows? We'll fix that fast.

Replacement Windows

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.

  • Insert and full-frame replacement options
  • 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–$1,000 per window installed. Multi-window discounts available.

Entry Doors

Quality doors at a fraction of the corporate price.

Entry Doors

A new entry door transforms the look and security of your home — and you shouldn't have to pay inflated corporate prices to get one. We install beautiful, solid entry doors in fiberglass, steel, and wood, handling everything from the rough opening to the hardware and weatherstripping.

  • Fiberglass, steel, and solid wood options
  • Deadbolt and hardware installation included
  • Proper weatherstripping and threshold sealing
  • Same-day installation on most standard sizes

Entry door installation typically starts at $1,000–$3,000 installed. Free on-site estimates always.

Patio Doors

Sliding or French — we install them right.

Patio Doors

Whether you're replacing a worn-out sliding door or upgrading to a French patio door, we handle the full installation — frame prep, proper sealing, and hardware. We work with all major brands and leave your home clean when we're done.

  • Sliding and French patio door installation
  • Frame repair and reinforcement when needed
  • Energy-efficient glass options available
  • Same-day installation on most standard door sizes

Patio door installation starts around $1,500–$5,000 installed. Call for a free on-site estimate.
