Cornerstone Doors lifetime warranty on garage door labour

A Warranty That Lasts as Long as You Own Your Home.

Every job we complete carries a lifetime warranty on labour. Not one year. Not five years. For as long as you own the property where we did the work.

Covered

What's Covered

Our lifetime labour warranty means that if any work performed by our technicians fails due to a defect in workmanship — ever — we come back and fix it at no charge. No service fee. No labour charge. No runaround.

  • All labour performed by Cornerstone Doors technicians
  • Any rework required due to errors or failures in how the job was done
  • Labour to replace a part that fails under its manufacturer warranty

Exclusions

What's Not Covered

We're straightforward about the limits. The lifetime warranty on labour doesn't cover:

  • Damage caused by misuse, vehicle impact, or accidents
  • Modifications made by a third party after our work is complete
  • Normal wear on consumable parts (weather stripping, rollers, lubricants)
  • Damage from extreme weather events, flooding, or fire
  • Cosmetic damage that doesn't affect how the door works
  • Pre-existing conditions identified at the time of the original estimate

Parts and materials are covered by the manufacturer's warranty, which varies by brand and product. We'll provide manufacturer warranty documentation at the time of service.

Parts & Manufacturer Warranty

Parts and materials we supply are covered by the manufacturer's warranty — typically 1 to 5 years depending on the product. If a part fails within its manufacturer warranty period, the replacement labour is covered under our lifetime labour warranty at no charge to you.

We'll tell you exactly what warranty applies to every part at the time of installation.
