Frequently Asked Questions
How fast can a technician get to me?
Same day across Toronto and the GTA, 24/7 for emergencies. Most calls are attended within hours.
Is the estimate really free?
Yes. No charge to come out and diagnose, no obligation. Nothing starts until you approve.
Can I use the door with a broken spring?
No. The opener is now lifting the full weight of the door. Forcing it can strip the opener, snap a cable or drop the door. Leave it closed and call.
Should I replace one spring or both?
Both. They wear at the same rate — when one breaks, the other is close behind.
Repair or replace?
Most doors can be repaired. We recommend a new door only when panels are badly damaged or rusted through. Honest recommendation, no sales pitch.
Is the work warrantied?
Yes. Every repair and installation is covered on parts and workmanship.
