Can you repair window frames?

Minor issues like rot, loose fittings or small cracks can often be repaired. a window-specialist will assess the damage and advise whether repair or replacement makes more sense. Photos and measurements can help the Window Specialist give clearer guidance.

Do you replace handles, hinges and locks?

Yes, hardware replacements are common. a window-specialist can fit new handles, hinges or locks and check alignment so the window opens and seals properly. If relevant, confirm how services will be isolated and when they will be restored.

Timing depends on the number of windows, access and the type of units. a window-specialist can give a realistic schedule once the scope and materials are confirmed. Share the age of the property, access, and what you want to change so the Window Specialist can plan the right approach.

Can I keep the same window style?
