Replacement Windows in the Pacific Northwest
Old, drafty windows are one of the biggest sources of wasted energy in a home — and one of the fastest upgrades to notice. Liberty General Construction installs energy-efficient replacement windows that seal tight, block outside noise, and instantly modernize your home's appearance. We handle the full job: careful removal of the old units, proper flashing and insulation, and a clean, weather-tight install.
Based in Vancouver, WA, we install double- and triple-pane windows with Low-E glass in a range of styles — double-hung, casement, slider, picture, and bay. Every install is measured precisely, sealed correctly, and backed by a workmanship warranty in addition to the manufacturer's coverage.

Window Replacement Questions
- It depends on the condition of your current windows and your home, but replacing old single-pane or failing double-pane windows with modern Low-E units typically reduces heating and cooling costs noticeably. Just as important, you'll feel the difference — no more cold drafts in winter or hot spots in summer.
- No. Many homeowners start with the worst offenders — the drafty, hard-to-open, or street-facing windows — and phase the rest over time. We're happy to quote the whole house or just the windows you want to tackle first.
- Yes. We offer double-hung, casement, slider, picture, and bay styles in a range of colors and grid patterns, so we can match your home's character or update the look entirely — whichever you prefer.
