Window Replacement in Manchester, NH

Insert or full-frame

An insert, sometimes called a pocket replacement, slides into the existing frame after the old sashes, stops and weights come out. The interior trim and exterior casing stay put. It's less work and less money, and on a sound frame it performs well. You do give up some glass, because the new unit sits inside the old jamb.

A full-frame replacement removes everything down to the rough opening. It costs more and disturbs trim inside and out, but it's the honest fix when the sill is rotten, the frame is out of square, or water has been getting in behind the casing. It also opens up the old sash-weight pockets, which in an old house are usually empty cavities leaking cold air all winter. Those can be insulated before the new unit goes in.

Which one a window needs often isn't clear until someone pushes a screwdriver into the sill. Soft wood at the bottom corners is the usual tell.

Old sash and lead paint

Double-hung wood sash from the early 1900s were painted for decades. The friction surfaces, where the sash slide against the jamb and stops, are exactly where lead dust gets made. EPA treats window replacement in a pre-1978 home as work covered by the Renovation, Repair and Painting rule. The firm doing it for pay has to be certified and follow lead-safe practices, containment and cleanup included.

Ask whoever you hire whether they're an RRP-certified firm and how they'll contain the work. You should also be handed EPA's Renovate Right pamphlet before work starts. If there are young kids in the house, that conversation matters more than the brand of window.

Energy ratings, the code and rebates

ENERGY STAR certifies windows by climate zone, and New Hampshire falls in the northern zone. The NFRC label on a new window lists its U-factor, a measure of heat loss. For a southern New Hampshire winter, that's the number to compare between quotes. Lower is better.

New Hampshire kept the 2018 energy code when the rest of its building code moved to the 2024 editions on July 1, 2026, and the state's energy code page explains what applies. Before buying, check NHSaves, the efficiency program run through the state's electric and gas utilities. Its rebates change from year to year, so look at what's current.

A window performs only as well as its install. The gap between the unit and the rough opening needs low-expansion foam or backer rod and sealant, and the outside needs flashing lapped into the housewrap so water drains out rather than in.

Windows with siding, doors and trim

The company's own posts group this work together: "Siding, windows & doors" in one reel, "Doors & Windows" in another. On an exterior job that makes sense. If the siding is coming off anyway, each window can be flashed to new wrap instead of caulked against old clapboard, and tired exterior trim gets replaced in the same pass.

Devin's description of the business is "I’m a General contractor that can do anything from frame to finish". On a window job that reaches past the unit itself, to the carpentry around it, the interior casing and the paint.

What to send for a quote

The business puts it simply: "Message us a photo — we’ll get you a number." Send each window from inside and outside, a close shot of the sill, the rough width and height, and how many there are. Note whether they're original wood sash or an earlier replacement, and roughly when the house was built.
