We visit your home, walk through every option together, and give you a transparent quote before we leave. Full-frame installation. Energy Star certified. Serving Ottawa and surrounding communities.
What We Install
Every project uses full-frame installation with Energy Star certified products. Free in-home consultation, same-visit pricing, and a 1-Year Installation Guarantee on every job.
Stop the drafts, cut the heating bill, let more light in. Full-frame installation in one day on most homes. Every window is Energy Star certified.
No more sticking. No more drafts. No more rotting at the base. A 100% wood-free composite frame seals the same way in July as it does in January.
Slides with one finger, even at 440 lbs. Twin locks and a steel-reinforced sash come standard, not as paid extras. Sliding and stacking configurations available.
Why Clearline
Built for Ottawa Winters
Ottawa temperatures drop below -30°C. Builder-grade windows fail at those extremes. Every window we install uses multi-chamber vinyl walls, Low-E coated glass, and argon gas fill between the panes — not as upgrades, as standard.
The cross-section shows how the frame profile traps air, how Low-E coating reflects heat back inside, and why galvanized steel reinforcement inside the frame keeps everything square after years of Ottawa freeze-thaw cycles.
The Process
Most projects go from first call to completed installation in 4 to 6 weeks.
