Optima 25-Year Performance Guarantee
We don't hide behind the word "lifetime." We guarantee your windows and doors will perform for 25 years. All-inclusive coverage. Parts and labour. No fine print.
A Window Warranty That Actually Means Something
Most window companies in Ontario offer what they call a "lifetime warranty." But when you read the fine print, you discover that "lifetime" only covers the vinyl frame, not the glass, not the hardware, and certainly not the labour. After the first year or two, you are on your own for service calls at $100 per hour or more.
Optima does things differently. Our 25-year Performance Guarantee covers every component of your vinyl windows and entry doors: the frame, the glass, the hardware, the installation, and any future service. If something goes wrong at any point during the 25-year term, we fix it. Free parts. Free labour. No excuses.
Because Optima manufactures, sells, and installs every product we deliver, there is no finger-pointing between a manufacturer and an installer. We are your single point of contact from the moment you request a quote to the day you need service 20 years from now.
Our warranty is fully transferable with no proof of purchase required, because we keep all records on file. That means when you sell your home, the next owner inherits the full remaining coverage, adding real value to your property.

12 Guarantees. Zero Fine Print.
Every Optima window and door installation in Ontario comes with these 12 specific performance commitments, backed for 25 years.
All-Inclusive Parts and Labour Coverage
Both parts and labour are covered for the full 25-year duration of the warranty. Free parts. Free labour. If anything fails or underperforms, we fix it at absolutely no cost to you. No service call fees, no hourly charges, no hidden costs.
Professional Installation Guarantee
End-to-end accountability with no subcontractors. Every Optima installation is performed by our factory-trained, WindowWise certified installers. Because we control the entire process from manufacturing to installation, there is never a gap in responsibility.
48-Hour Service Response Guarantee
When you need service, our office will be in touch within 48 hours to outline the next steps in getting your windows or doors serviced. No waiting weeks for a callback. No automated phone trees. Real people, fast response.
Guaranteed response, not a voicemailDraft-Free Performance Guarantee
Your energy-efficient windows will remain draft-free for the entire 25-year warranty term. If you feel a draft coming through a closed, locked Optima window at any point during the warranty period, we will resolve it at no charge.
Free Condensation and Humidity Support
New windows change your home's ecosystem, and condensation is typically caused by indoor humidity, not a product defect. While condensation is excluded from the warranty, Optima offers free humidity assessments and coaches you on prevention. Every installation includes a complimentary "Healthy Home" humidity audit during your first winter.
Free humidity audit included"No-Bull" One-Stop Warranty
You never need to contact anyone else. Optima stands behind the entire warranty, and we are your only point of contact for any issue. No getting bounced between a manufacturer, a dealer, and an installer. One call. One company. One resolution.
Security Break-In Guarantee
If a burglar gains entry through a locked, warranted Optima window equipped with Roto multi-point lock and Corner Drive hardware, Optima will pay your home insurance deductible. That is how confident we are in the security performance of our German-engineered locking systems.
Insurance deductible coveredAccidental Glass Breakage Coverage
Life happens. Baseballs fly. Lawnmowers kick up rocks. With Optima, accidental glass breakage is covered under warranty. Save yourself $500 to $1,500 per replacement. No repair bills, no stress, no extra insurance claims needed.
Free Screen Mesh Replacement
Bring us your screen and we will replace the mesh for free. Pets, kids, weather, and normal wear can all damage screen mesh over the years. Instead of paying $50 to $150 per screen at a hardware store, simply bring it to Optima.
German Engineering Excellence
Our premium Roto hardware from Germany is guaranteed not just against manufacturing defects. Optima guarantees smooth and consistent operation for the full 25 years. Cranks, handles, tilt mechanisms, and locks will perform as well in year 20 as they do on installation day. Explore our casement, awning, and tilt and turn windows to see this hardware in action.
Ontario Winter Durability Coverage
We are so confident in our German-engineered sealed units that if a stress crack occurs in the glass during the first year, we replace it completely free of charge, including parts and labour. Ontario winters push windows to their limits with freeze-thaw cycles. Our triple-pane sealed units are built for exactly that.
