What Our Satisfied Clients Say
Frequently Asked Questions About Casement Window Repair
How can I tell if my casement window can be repaired or needs replacement?
Signs that repair is feasible include: hardware problems (difficult cranking or locking), minor wood deterioration, foggy glass, or draft issues. Complete replacement is typically only necessary when frames have severe structural damage, extensive rot (in wooden windows), or when the cost of multiple repairs would exceed replacement.
What is typically involved in repairing a casement window?
Repair typically includes diagnosing the issue, removing damaged parts, cleaning, installing new parts (hinges, etc.), aligning, and testing. Most repairs take 1-3 hours per window, though complex restoration may take longer.
How much does casement window repair typically cost?
Repair costs average 30-70% less than full window replacement, making it a cost-effective option when possible. We provide detailed estimates before beginning any work.
Can you match my existing casement windows if partial replacement is needed?
Yes, we excel at matching existing windows. We’ll identify your window’s details to source exact components or custom-fabricate matching elements, ensuring a seamless look.
Do repaired casement windows perform as well as new ones?
Properly repaired windows can perform excellently for years. While new windows may offer slight efficiency gains, well-repaired windows with good weather stripping often perform comparably. We also offer glass upgrades for better efficiency.
