Parts and labour covered for 20 years
Every window and door installed by GTS Windows & Doors is backed by a 20-year parts and labour warranty. In plain terms, if a covered part fails, the replacement part and the work to fit it are both included, and your first call is to us. The warranty applies to the windows and doors we supply and install.
We have installed windows and doors in Kitchener-Waterloo homes and businesses since 1986, and that experience is why we treat labour as part of the promise. Many warranties in this industry cover the window or door itself but say little about the cost of a technician to diagnose and fix it, which is often the larger part of a service call. A warranty that pays for the glass but not the visit to fit it can still leave you with a sizeable bill.
This page explains what a parts and labour warranty like ours typically covers, what it does not, how it works alongside the manufacturer's product warranty and how to make a claim. Your signed contract and written warranty document set out the exact terms for your job, and they take priority over this general summary. If anything in your paperwork is unclear, ask us to walk through it before you sign.
Seal failure is a common example. If a covered sealed unit starts fogging between the panes, the replacement glass unit and the labour to install it fall under the warranty.
Like most installation warranties, ours protects against product and workmanship defects, not every kind of damage. Typical exclusions include the following.

Most window and door manufacturers issue their own product warranty, with terms that vary by component. Our 20-year parts and labour warranty works alongside it, so you have one local company to call instead of chasing a factory.
| Coverage point | Typical manufacturer warranty | GTS 20-year warranty |
|---|---|---|
| Who you contact | The manufacturer, often through a dealer | GTS directly |
| Replacement parts | Per the manufacturer's terms, sometimes prorated | Included for 20 years |
| Labour to fit parts | Often limited or excluded | Included for 20 years |
| Installation defects | Not covered | Covered under our written terms |
Whether coverage passes to a new owner depends on the terms in your written warranty, and manufacturer warranties have their own transfer rules. If you plan to sell, ask us to confirm the transfer terms in writing so you can hand the paperwork to the buyer.

We review what you send and book a visit to inspect the window or door and confirm the cause.
Covered parts are ordered and fitted at no charge for parts or labour. If a part needs ordering, we make the opening secure and weathertight in the meantime.
A few common home projects can affect coverage. Talk to us before making any of these changes.

Some companies advertise lifetime warranties, but these often cover only certain components, may be prorated, can be limited to the original owner and frequently exclude or cap labour. Our warranty is 20 years and covers both parts and labour for that full term. When comparing quotes, check what each warranty actually pays for, not just how long it lasts.
Breakage from an impact, such as a ball, a stone thrown by a mower or a break-in, is accidental damage and is generally not covered. Seal failure that causes fogging is a product defect and is typically covered. We can replace broken glass as a separate glass replacement job, and your home insurance may help with the cost.
Commercial projects receive written warranty terms as part of each contract. Storefront systems, door closers and other commercial hardware can carry different manufacturer terms, so we spell out coverage at the quote stage. Learn more about our commercial window and door work.
