Frequently Asked Questions About Window Repair in the GTA
Common questions about window and door repairs, glass replacement, and hardware issues.
In most cases, only the glass unit needs to be replaced, not the entire window. Fogging usually means the seal between the panes has failed. Replacing the insulated glass restores clarity and insulation without the cost of full window replacement.
Not usually. Many opening and closing issues are caused by worn cranks, hinges, balances, or alignment problems, which can often be repaired or replaced. We always assess repair options before recommending replacement.
Misalignment can occur due to normal building movement, worn hinges, or long-term use. This can cause sticking, drafts, or difficulty locking. Proper alignment restores smooth operation and helps prevent further damage.
Yes. We repair and replace window cranks, operators, locks, hinges, and other hardware for many window and door types. If hardware is worn or broken, replacing it often restores full functionality.
In many cases, yes. Repairs such as glass replacement, hardware repair, or realignment are typically far more cost-effective than full replacement. If replacement is the better option, we’ll explain why clearly and honestly.
