Window repair across San Diego County

Sometimes. The fog between the panes is caused by a failed seal on the insulated glass unit (IGU), which allows humid air to enter the cavity. If the sash and frame are in good condition, the IGU can be replaced without replacing the sash or frame. If the sash itself is damaged or the frame is corroded or rotted, a full window replacement makes more sense.

IGU replacement for a standard dual-pane window typically runs $150-$350 per unit in San Diego, depending on glass size and whether any special coatings are needed to match the existing windows. Hardware repair (operator, latch, or lock) runs $100-$250 depending on the part and the labor time. The crews we refer diagnose the problem before quoting so you are not paying for work that is not needed.

Seal failure on dual-pane windows is caused by thermal cycling: the glass and spacer materials expand and contract with temperature changes, and over years this fatigues the sealant around the IGU perimeter. Coastal locations have high humidity, which accelerates moisture intrusion once the seal starts to fail. UV exposure on south and west-facing windows also degrades the sealant over time. Most IGU seals have a 10-20 year service life.

Yes, on most window types. Replacement weatherstripping is available for common vinyl, aluminum, and fiberglass window lines. The right material depends on the window brand and style: pile weatherstripping for sliding windows, foam or rubber compression strip for double-hung and casement. Replacing worn weatherstripping is one of the most cost-effective ways to reduce air infiltration without replacing the window.

If the problem is limited to the glass seal, a broken operator, or worn weatherstripping, and the frame and sash are structurally sound, repair is likely the right call. If the frame is rotted, corroded, or significantly out of square, or if multiple problems are present at once, a full replacement is usually more cost-effective over the long term. The crews we refer assess both options and give you a straight recommendation.
