Warranty &
After-Sale Service

Sealed units manufactured and installed by Cossins Windows Ltd. from January 1, 2015 are warranted for 20 years from the date of purchase against loss of the air seal due to defects in materials or workmanship. Contact Cossins about coverage for earlier installations.

This coverage does not include cracked or broken glass caused by heat build-up, spontaneous breakage, accidents or abuse. Coverage is void if a sealed unit is altered from its original state, including the application of solar-control films, stickers or paint, or the installation of blinds closer than two inches to the glass.

Condensation on the room-side surface of the glass is different from a failed sealed unit. Indoor humidity and temperature can cause surface condensation; this is not the same as moisture between the panes caused by loss of the air seal.

Cossins PVC window frames and sash members carry a 20-year warranty against defects in materials and workmanship that may result in blistering, flaking or corrosion.

Painted frames and sashes are not covered. Harmful solvents and abrasive brushes or cloths used to clean the vinyl can also invalidate coverage. Use appropriate non-abrasive cleaning methods.

Cossins aluminum / metal cladding is warranted to be free of defects in materials and workmanship for 20 years from the date of installation.

Gradual fading, surface dirt and staining from sunlight, air pollutants and everyday weather are normal conditions and are not covered by this warranty.

Window and door operating hardware supplied through Truth Hardware is warranted to remain in good operational condition for ten years. Door handle sets have the separate five-year term described below.

This coverage does not include finish discolouration, corrosion-related damage, or products that have been improperly installed, abused, misused, worn out or altered. The applicable Truth Hardware warranty provides the detailed manufacturer conditions.

Multi-point door hardware carries ten-year coverage, and door handle sets carry five-year coverage against defects in materials and workmanship and for good operational condition. Multi-point hardware is an optional feature, not a standard inclusion on every door.

Scratches or abrasions on finishes, alterations, improper installation, abuse and normal wear and tear are not included.

Smooth-panel fibreglass slabs have a 25-year limited warranty. Wood-grain fibreglass slabs have a limited lifetime warranty. Steel slabs have a ten-year limited warranty. These are door-slab terms, not blanket lifetime coverage for the complete installation or every Cossins product.

Coverage begins on the installation date and relates to manufacturing defects in materials and workmanship. The applicable product and manufacturer warranty determines the limited coverage for your particular slab.

The door panel, trim and jamb must be completely painted or stained on all six sides within 30 days of installation; failure to do so voids this coverage. Contact Cossins for the finishing requirements applicable to your door, including factory-finished products.

Doorlites are warranted for ten years from purchase against manufacturing defects in materials and workmanship. Damage caused by accident, negligence, or installation in abnormal or extreme locations or situations voids coverage.

If a defective decorative pattern is no longer available, Cossins will make a reasonable effort to find a suitable replacement of equal or lesser value. No substitutions are allowed when the same decorative style is still available from the manufacturer.

If a Craftsman-style door slab is defective, the entire slab needs to be replaced. Cossins will arrange for the door manufacturer to replace the slab, including the defective doorlite, at no charge under the applicable warranty.
