Why Choose Clearline

Four reasons Ottawa homeowners choose us. Every one is verifiable.

NAFS-22 Certified

Products That Meet Canada's Highest Standard

We install Stage Windows & Doors, independently tested and certified to NAFS-22, Canada's current structural performance standard. Most budget window brands do not meet it. Every window and door we install does.

Verified by independent third-party testing
Energy Star Certified

Up to 45% Lower Energy Bills

According to Natural Resources Canada, replacing windows with Energy Star certified products saves Ottawa homeowners an average of 45% on energy costs. That is a measurable return on a real investment, not a marketing estimate.

Written Warranty

Backed by Two Separate Warranties

Your installation comes with our 1-year installation guarantee. The Stage products carry a separate manufacturer warranty, lifetime on vinyl frames, 20 years on glass, 15 years on hardware. Both transfer to the next owner at no charge.

Fully transferable to the next owner
Full-Frame Only

Installation That Actually Solves the Problem

We only do full-frame installation. Everything stripped to the stud opening, replace the insulation, seal it properly. Ottawa's -30°C winters expose every shortcut. Full-frame eliminates drafts at the source rather than covering them up.

The only method we trust enough to warranty

What Ottawa Homeowners Are Saying

Real experiences from Ottawa homeowners who've upgraded their windows and doors.

"We had 11 windows replaced in our 1998 home. The difference in warmth that first winter was immediate, no more cold air near the frames in the living room. The crew was in and out in one day and left the place spotless."
Margaret & Tom B.

Window Replacement
"Finally replaced our original builder-grade front door after 20 years. The new door seals completely. You can feel the draft difference the moment you close it. Installation was clean, professional, and done in a few hours."
Daniel K.
Kanata
Entry Door Installation
"Our patio door used to stick every summer and let cold air in every winter. The new one slides with one finger and locks solidly. We noticed the difference in our heating bill by the second month."

Frequently Asked Questions

Quick answers to help you make an informed decision

How much do new windows cost in Ottawa?
Standard vinyl windows start from $600 per window installed, with most casement and awning styles running $800–$1,300+ once glass package, colour, and configuration are factored in. Custom shapes, triple-pane, or premium options will go higher. A full-home project (around 10 windows) typically starts around $8,000, with most Ottawa homes in the $10,000–$18,000 range depending on scope and selections. Get an exact price for your home →
Should I choose double-pane or triple-pane windows?
Double-pane (Low-E coating + argon gas) works well for most Ottawa homes. Triple-pane costs 15-25% more but cuts heat loss by up to 40%, worth it if you're in an older home or plan to stay long-term. We'll walk you through both during your free consultation.
Why don't you offer retrofit installation?
Because it doesn't hold up in Ottawa's climate. Full-frame installation strips everything down to the studs, replaces the old insulation, and seals it properly. Retrofit leaves the old frame in place. Fine for mild climates, but not when temperatures swing from -30°C to +30°C. It's the only method we trust enough to back with our 1-Year Installation Guarantee.
How long does installation take?
1-2 days for most projects. Ten windows usually takes one full day. We install one window at a time. The opening is never exposed. Drop cloths, full cleanup, minimal disruption. You'll get an exact timeline after we measure.
Do you offer financing?
Yes. Ottawa homeowners can access the Better Homes Ottawa Loan Program, up to $125,000 at 4.33% fixed interest over 20 years for energy upgrades including windows and doors. The loan is tied to the property, not you personally, so it transfers to the next owner if you sell. We also accept cheque, e-transfer, and credit card. Ask us about financing during your free quote →
What warranty comes with new windows?
Every installation comes with our 1-year installation guarantee covering the installation itself. The Stage Windows products carry a separate manufacturer warranty: lifetime on vinyl frames, 20 years on insulating glass, and 15 years on hardware. Both are fully transferable to the next owner at no charge, adding documented value to your property when you sell.
