The Ultimate Checklist: When to Replace Windows in Colorado Homes

Wondering if it’s finally time to upgrade your windows? Whether your home is brand new or decades old, your windows play a major role in comfort, efficiency, and curb appeal. In this guide, we’ll break down the most important signs that your windows are due for replacement—especially if you live in the unique climate of Colorado.

Poor Appearance

Do your windows look foggy, faded, or stained between panes? If you notice condensation, discoloration, or cloudiness, it could mean your window seals have failed. That not only hurts your home’s aesthetic—it also impacts energy performance and resale value. Modern fiberglass windows resist this better than vinyl.

Draftiness

If you feel cold air creeping in around your window frames during Colorado winters—or heat seeping through in the summer—your windows are not performing. Drafts often come from warped frames, failed seals, or shrinkage over time. That’s money leaking right out of your house.

They’re Outdated

If your windows are 15+ years old or still single-pane, you’re likely missing out on today’s performance standards. Older windows warp, lose efficiency, and stick out visually. Upgrading to modern Infinity from Marvin fiberglass windows can dramatically improve both aesthetics and thermal performance.

High Energy Bills

Drafts and poor insulation force your HVAC system to work overtime—especially in Colorado’s shifting temperatures. ENERGY STAR®–rated windows with Low-E glass and proper installation can reduce energy loss by up to 50%, according to the U.S. Department of Energy.

Rotting or Damaged Trims

Check the trim and sills around your windows. If they’re cracked, soft, or rotting—especially on wood frames—it’s not just an eyesore. It could mean water intrusion, mold risk, and structural concerns. Replacing the entire unit may be the most effective solution.

Hard to Open, Close, or Lock

Windows should open and close easily and lock securely. If they’re stuck, constantly slipping down, or require force to budge, it’s time for new ones. Function matters—especially for emergency egress and safety.

You’re Selling Your Home

First impressions matter. New, energy-efficient windows can increase your home’s resale value by as much as $9,000. They also photograph better for listings, improve curb appeal, and give buyers confidence in the home’s condition.

Can’t Sleep at Night?

Live near a busy street or noisy neighbors? Older windows let in sound. Modern fiberglass windows offer better sound insulation and help create a quiet, restful home environment—day or night.
