Most windows last 15–20 years before their efficiency and functionality start declining. Expect issues like weakened seals, drafts, condensation between panes, and warping. Around or beyond 20 years, replacement is generally recommended.

Watch for:

Drafts or cold/hot air penetration

Difficulty opening or closing windows

Condensation or fog between panes

Visible damage, seal failure, or warped frames

Increased noise infiltration

Energy cost spikes

Early spring or fall are ideal due to milder, more predictable weather—these seasons help minimize heat or cold exposure during installation.

You can replace windows in winter, but be mindful of the challenges: cold, snow, and shorter days. Experienced contractors can still manage the process effectively with proper planning.

You typically do not need a permit if you're doing a like-for-like window swap without modifying the opening. However, a permit may be required if:

You change the window size or location

The window serves as an egress in a bedroom

Safety glazing is necessary (e.g., near bathrooms or stairways)

Frame materials:

Vinyl: Affordable, low-maintenance, good insulation.

Wood: Classic aesthetics, customizable, but needs upkeep

Fiberglass: Strong, energy-efficient, low-maintenance

Aluminum: Lightweight, durable, but less insulating

Glass & performance:

Favor windows with Energy Star certification tailored to Colorado's climate zone

Review NFRC ratings—specifically U-Factor (insulation) and SHGC (solar heat gain)—lower is better

Choosing the right balance of U-Factor and SHGC helps with heating in winter and cooling in summer

Minor cosmetic issues (like cracked glass or hardware problems) can often be repaired. But consider replacement if:

Seal failures or fogging persist

Frames are warped or rotten

Energy inefficiency or comfort issues are significant.

Modern replacements often deliver enhanced energy savings, comfort, and property value—even if ROI isn't immediate

Most homes’ window replacements can be completed in 1–4 days, depending on house size and project complexity. Some contractors even handle full-home replacements in a single day—commonly referred to as “one-day installs.”
