Scope, product, and warranty

Make every quote comparable on the same line items, per opening.

  • Is this quoted as an insert or a full-frame replacement, per opening?
  • What are the U-factor and SHGC on the exact product line quoted?
  • Who pulls the permit, and is the permit fee in the price?
  • Is the crew employed by the company or subcontracted?
  • What is covered under labor warranty vs. manufacturer warranty, and for how long?
  • What happens if rot or framing damage is found once the old unit comes out?
  • Is disposal of the old sash and cleanup included?
  • For pre-1978 homes: are lead-safe work practices being followed?

Frequently asked questions

Is it reasonable to ask for financing terms in writing?+

Yes. Reputable companies expect it. If a company refuses to put financing terms in writing, that is the answer.

Should I sign at the in-home appointment?+

No. Same-day discount pressure is the most common red flag in this trade. A legitimate price is still there tomorrow.
