How we pick the best one (no star ratings)
1. We start with real local businessesEvery listing has a local address and a working phone number from public business records.
2. We call and askYears in business, licensing where your state requires it, insurance, and whether they actually answer and show up.
3. We match to your must-havesExperience, what matters most to you, and how close they are to your house.
4. We ask you how it wentAfter the job we check in with you. Pros who fall short stop getting our referrals.
We don't use Google or Yelp reviews. Ratings can be bought, gamed or years out of date; a phone call and your feedback can't. More on how we check pros.
Hired the wrong window installer before?
No-shows, a job left half done, a price that doubled. It happens a lot, and it's why we check window installers ourselves instead of trusting star ratings. Tell us what went wrong last time, tick "let down before" on the form, and we'll only send you pros who passed our check and fit your must-haves.
