What to check when hiring window / door fitters in the United States

MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.

  • Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemized quote you can take away and compare against others.
  • Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
  • Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
  • Contractor licensing in the US is set by each state (and sometimes the city or county). For electrical, plumbing, HVAC or any major build, confirm the trade is licensed on your state's licensing board before hiring. Unlicensed work where a license is required can void permits and insurance and leave you no recourse.
  • Ask for a lien waiver as you pay each stage: in most US states an unpaid contractor or subcontractor can place a mechanic's lien on your home even if you already paid the main contractor, and a signed waiver is your protection.

How to judge a window / door fitter

Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each contractor’s public evidence above.

Verify before you hire

  • Window or door replacement over your state's threshold may need a home-improvement or contractor license/registration: verify where required.
  • AAMA/FGIA InstallationMasters certification signals a proper, weather-tight installation; ENERGY STAR-rated units may qualify for tax credits or rebates.
  • Confirm general liability and workers' compensation, and that flashing, sealing, and insulation around the frame are included: not just a 'pop it in' job.
  • Get the product line, the U-factor and SHGC ratings, and the warranty (product AND labor) in writing.

Warning signs of a rogue contractor

  • High-pressure in-home sales: a 'today-only' price that expires when the rep leaves.
  • Vague about flashing, sealing, and insulation around the new frame.
  • A huge up-front deposit before the custom units are even ordered.
  • No license where required, and no insurance.

Questions to ask before you hire

  • Do you hold the license (where required) and carry insurance?
  • Are installers AAMA/FGIA InstallationMasters certified?
  • How do you flash, seal, and insulate around the frame?
  • What are the product ratings, and the product plus labor warranty?

Frequently asked questions

How do I choose a trustworthy window / door fitter?
Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. A window / door fitter backed by several named sources is harder to fake than one found in only one place.
Does MyTrustedTraders rank or recommend window / door fitters for payment?
No. There are no ads and no paid placement. Window / door fitters are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
Where do the reviews come from?
They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
What should I check before hiring a window / door fitter?
Confirm credentials and insurance directly with the window / door fitter, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
