Lehi is a moderate-high cost-of-living market — pricing guide and permit rules below.
Lehi window replacement rates: $3,500-$12,000 per system. Lehi's extreme heat accelerates wear. Always get 3 written quotes and verify UT licensing at Utah DOPL (dopl.utah.gov). Sales tax on materials: 7.1%.
Lehi requires permits when work exceeds $3,000 or involves full system replacement. Your licensed contractor pulls the permit — if they ask you to pull it, that's a red flag.
