Window Replacement Contractors in Kent, Washington
Residential window replacement and installation..
Replacing old single-pane or failing double-pane windows with modern energy-efficient units can dramatically reduce heating and cooling costs while improving comfort and curb appeal. Vinyl, fiberglass, and wood-clad frames each offer different aesthetics and maintenance profiles. Low-E glass coatings, argon fills, and triple-pane options further boost insulation. A quality window installer ensures proper flashing, shimming, and insulation around the frame to prevent air and water infiltration — poor installation negates the benefits of even the best window.

General Window Replacement FAQs
How much does window replacement cost?
Window replacement costs $400–$1,200 per window installed depending on frame material, glass type, and size. Vinyl double-hung windows are the most affordable at $400–$800 each installed. Fiberglass and wood-clad windows run $700–$1,200+. A whole-home project (10–20 windows) typically costs $6,000–$18,000. Insert (pocket) replacement — fitting a new window into the existing frame — is less expensive than full-frame replacement, which involves removing the entire window assembly including trim and casing.
How do I know when to replace my windows?
Replace windows when you notice drafts around closed windows, condensation or fog between double-pane glass (indicating seal failure), difficulty opening or closing, visible rot in wood frames, or noticeably higher energy bills. Single-pane windows should be replaced with double or triple-pane Low-E units for energy savings. Most modern windows pay back their cost in energy savings within 7–12 years while improving comfort immediately.
What is the difference between insert and full-frame window replacement?
Insert (or pocket) replacement fits a new window unit into your existing window frame, leaving the original frame, trim, and casing in place. It's faster, less expensive, and causes less disruption. Full-frame replacement removes everything — the entire window assembly including the frame — and installs a completely new unit. Full-frame is necessary when the existing frame is rotted, damaged, or out of square. It costs 30–50% more but provides the opportunity to add insulation, update flashing, and address any hidden water damage.
