Signs Your Des Peres Home Needs New Windows

Not sure if it’s time? Here are the most common signals homeowners notice:

Fog or Condensation Between the Panes

When moisture appears trapped between glass layers, the insulating seal has failed. Energy performance is compromised, and cleaning won’t fix it.

Drafts Even When Windows Are Closed

Cold air near the windows in winter—or warm air in summer—even when everything is shut and locked. Especially common in homes with original wood frames that have been through decades of Missouri’s freeze-thaw cycles.

Difficulty Opening, Closing, or Locking

Windows that stick, won’t stay open, or don’t latch properly. This is more than an inconvenience—it’s a sign that the frame has shifted or warped enough to affect operation.

Visible Rot or Soft Spots

Soft spots in wooden frames, peeling paint that keeps coming back, or water staining around the window. These signs mean moisture has gotten behind the window, and an insert won’t solve the underlying problem.

Rising Energy Bills

Older single-pane or failed double-pane windows are a major source of energy loss—particularly in homes that predate modern energy standards.

Energy Efficiency Worth Noting

Des Peres’ median construction year is 1975, meaning most homes predate modern energy standards. Replacing aging double-pane or original single-pane windows with Marvin windows—featuring low-E glass, insulating gas fills, and fiberglass or wood-clad frames—can make a noticeable difference in comfort and energy costs. Full-frame replacement compounds the improvement by sealing the wall cavity behind each window.
