Storm Door Installation in New Hampshire

Q: One company quoted $350/window and another quoted $1,200/window. What am I actually getting?

The gap usually reflects glass package (double vs triple pane, low-E coating, gas fill), frame material (vinyl vs. fiberglass vs. wood), brand reputation, and installation quality. A $350 window may have a 1-year warranty; a $1,200 window may have a lifetime warranty. Ask for U-factor and SHGC ratings in writing — these are measurable performance specs.

Q: The installer cracked my window frame during installation. They said it 'happens sometimes.' Is this acceptable?

No. Cracked frames during installation indicate careless handling or incorrect installation technique. The installer should replace the frame at no charge to you — document the damage with photos before any 'repair' is attempted. 'It happens sometimes' is not an acceptable standard of workmanship.

Q: Do new windows actually pay for themselves in energy savings?

In most climates, the energy savings alone rarely cover the full replacement cost within a reasonable timeframe. The real value is in comfort, noise reduction, reduced condensation, and home value. If a salesperson shows you a payback calculation, ask for the assumptions — they're often optimistic. Choose windows for the comfort and durability, not purely ROI.

Q: My window installer is asking for 60% upfront on a $14,000 order. Is that reasonable?

For custom-ordered windows, a deposit covering the cost of materials (typically 40–50%) is industry standard. But never pay 100% upfront. A payment split of 50% at order, 50% on completion is fair. Get a written contract specifying the exact products being installed, installation timeline, and what happens if windows arrive damaged.

Q: How long does window replacement typically take per window?

Professional installers typically replace 8–12 windows per day. A whole-house replacement (15–20 windows) usually takes 1–2 days. If a company quotes significantly longer, ask why. You should expect to be home during installation for access and final walkthrough, but the disruption per window is usually 30–60 minutes.

Common questions

Frequently asked questions in NH

My new windows are still drafty. Did the installer do something wrong?

Drafts from new windows almost always indicate improper sealing or installation — not a product defect. The exterior trim caulking, interior foam insulation, and weather stripping all need to be done correctly. Contact the installer in writing and ask them to do a blower door test or at minimum a smoke pencil test to identify where air is entering.
