How Do You Know When It's Time?

Windows don't usually fail dramatically — they deteriorate slowly. By the time most Houston homeowners notice a problem, they've been paying extra in energy bills for months or years.


Sign 1: Condensation or Fogging Between the Glass Panes

Foggy condensation between double-pane window glass
That cloudy film between the panes means the insulating gas has leaked out — this window is now performing like single-pane glass

This is the most definitive sign a double-pane window has failed. That foggy film between the glass layers means the insulating gas has leaked out and moisture has gotten in.

⚠️ This cannot be repaired
Once the seal fails and moisture gets between the panes, the only fix is replacement. The window is now performing like single-pane glass and costing you money every day.

Sign 2: Drafts You Can Feel

Hold your hand near the window edge on a hot day. Feeling air movement? The weatherstripping has failed, the frame has warped, or the seal has broken. In a Houston summer, your AC is fighting that draft all day long.


Sign 3: Your Energy Bills Are Climbing

20–35%
Typical Cooling Bill Savings
$200–$400/mo
Average Houston Summer Bills
15–20 yrs
Age When Single-Pane Fails

If your cooling costs have increased despite no major change in habits or equipment, your windows may be the culprit. Old windows allow significant solar heat gain — new ENERGY STAR-certified windows can cut cooling costs by 20–35%.


Sign 4: Difficulty Opening, Closing, or Locking

Windows that are hard to operate have usually warped (wood frames) or have hardware that's failed. Beyond the inconvenience, windows that don't close completely are a security risk. If you can't lock it, you can't secure it.


Sign 5: Visible Damage — Rot, Cracks, Water Stains

Rotting wood frames, cracked frames, or water staining around the window trim all indicate moisture intrusion. Left unaddressed, this becomes a mold and structural problem, not just a window problem.


Sign 6: Excessive Outside Noise

Good modern windows significantly reduce outside noise — traffic, lawn equipment, neighbors. If you can hear everything outside clearly, your windows have thin glass or failed seals.


Sign 7: Your Windows Are More Than 20 Years Old

Most residential windows installed before 2000 predate current Low-E glass standards. Even if they're not visibly failing, you're paying significantly more in energy costs than necessary.

"In Houston specifically, any pre-2000 window is missing out on the solar heat blocking improvements that matter most for Texas summers."
