Window Frame Repair FAQs
How much does window frame repair cost in St. Louis?
Window frame repair in St. Louis typically costs $200-$600 per window, saving 70-80% compared to full window replacement ($800-$2,500+). Cost depends on rot extent and window size. Most frames are restored in 2-4 hours per window.
Can rotted window frames be repaired?
Yes, most rotted window frames can be repaired using epoxy consolidants and wood fillers. We remove soft, damaged wood, treat remaining structure with penetrating epoxy, then rebuild the profile with structural filler. Repairs are stronger than original wood.
How do I know if my window frames have rot?
Signs of window frame rot include soft or spongy wood when pressed, peeling paint that won't stay on, visible gaps between frame and wall, water stains on interior walls, difficulty opening windows, and increased drafts. Early detection prevents costly damage.
Is window frame repair worth it vs replacement?
Window frame repair is usually worth it when the glass and sash are in good condition. Repair costs 70-80% less than replacement, preserves original character in historic homes, and completes in hours instead of days. Only replace if the entire window unit is failing.
