Frequently asked questions about Window Replacement in New Hampshire

Single-hung vs double-hung — what's the price difference?
Double-hung windows (both upper and lower sash slide) cost $50–$150 more per window than single-hung (only lower sash moves). Double-hung are easier to clean from inside and better for upper-floor windows. Single-hung wins on price and slightly better energy efficiency — fewer moving parts means tighter seals.
How much does it cost to replace all windows in a typical house?
A standard 3-bedroom house has 12–16 windows. Replacing all with mid-tier vinyl double-pane: $5,000–$12,000 installed. With premium fiberglass + Low-E triple pane: $12,000–$22,000. Whole-house jobs usually get 5–10% volume discounts. Plan for 2–3 day install with a 3-person crew.
Insert vs full-frame replacement — when do I need each?
Insert (pocket) replacement fits new windows inside existing frames — cheapest at $400–$900/window, takes 30–45 min per window. Use this if frames are solid (no rot, no warping). Full-frame replacement tears out the old frame to the studs — $700–$1,800/window. Required if you see water damage, soft wood, mold around the frame, or the existing frame is bent/out-of-square.
Andersen, Pella, Marvin, Milgard — which brand?
All four make quality windows; the price ladder runs Andersen 100/200 < Milgard < Pella < Andersen 400 < Marvin. Milgard offers best value in the West (made in CA/WA). Andersen 400 Series and Pella Lifestyle are the volume mid-premium picks nationally. Marvin Signature is the premium tier ($800–$1,800/window) for wood-clad and historic-match. Avoid window companies that won't name the brand they install — they're typically reselling generic vinyl at premium markup.
Are Energy Star windows worth the upgrade?
In northern-tier states (climate zones 5–7), the upgrade from double-pane to triple-pane Low-E pays back in 8–14 years through heating savings. In southern states (zones 1–3), Low-E with argon fill on double-pane is the right tier — triple pane is overkill and rarely pays back. The federal Residential Energy Efficient Property Credit (30% of cost up to $600/year for windows) cuts net cost meaningfully.
