Ottawa's Window & Door Specialists

Premium Window & Door Replacement, Managed End to End

Clearline handles everything: product selection, custom configuration, project management, and quality-controlled installation, so Ottawa homeowners get the result they were promised.

A Different Approach to Window Replacement

Most window companies are volume operations. They move fast, quote aggressively, and rely on homeowners not knowing what questions to ask. Clearline works differently.

We specialise exclusively in windows and doors. Nothing else. That focus means every consultation is led by someone who understands energy performance, Ottawa's climate demands, and the difference between a product that will perform for 20 years and one that won't.

We manage your project from the initial consultation through to installation completion, coordinating every detail, sourcing certified products, and ensuring the result matches what we quoted. Your project is backed by our 1-Year Installation Guarantee and the Stage Windows manufacturer warranty.

Ottawa-Based

We work exclusively in Ottawa and the surrounding region. Your neighbours' homes are our references. Our reputation depends on every project we complete.

Windows & Doors Only

We don't do general contracting, renovations, or roofing. Windows and doors. That is our entire focus, which is why we know the products and the process better than generalists.

Transparent From Day One

Written quotes with no hidden fees. A free consultation with no pressure. A warranty that's clearly defined in writing. You know exactly what you're getting before you agree to anything.

Why We Use Stage Windows & Doors

We evaluated multiple Canadian window manufacturers before choosing Stage as our primary product line. The criteria that mattered most: independent certification, climate-specific engineering, and products we'd be confident warranting.

NAFS-22 Certified (Canada's current structural performance standard, independently tested.)
Energy Star Certified (Verified energy performance for Canadian climate zones.)
Slim-Profile Frames (More glass area in the same opening, meaning more natural light.)
Canadian Manufacturer (Designed and tested for conditions like Ottawa's.)
Hidden Internal Drainage (No exterior plastic weep hole flaps. Clean exterior finish.)
Composite Entry Doors (100% wood-free frames. No rot, no warping, ever.)
