The new windows have made our home noticeably warmer and significantly quieter throughout.

Amelia Thomas

Mar 14, 2026

Our windows fogged up and the front door no longer closed evenly. These problems affected comfort and appearance. The house felt outdated. After replacement, everything looks clean and functions properly. The home feels refreshed

Bennett

We replaced old windows and doors that no longer performed well. Drafts and outside noise were everyday problems. The house never felt fully comfortable. After the upgrade, the home feels calmer and more energy-efficient. The improvement is noticeable in every room.

Lucas

We chose to replace both windows and doors after years of minor repairs. The problems always returned eventually. After installation, everything feels solid and reliable. The upgrade was worth it.

Our entry door was replaced due to visible wear and security concerns. The new door feels solid and dependable.

Before you hire a window and door installer in Ontario

No provincial licence is required. Installation quality is governed by manufacturer specification and the Ontario Building Code rather than by a trade certificate.

General liability insurance and WSIB clearance

Standard checks. Window installation involves ladder work and heavy glass.

Manufacturer-trained installer status

Matters more than usual here, because most window warranties are voided by installation that departs from the manufacturer specification.

Building permit for new or enlarged openings

Replacing a window in an existing opening generally does not need one. Cutting a new opening, or enlarging one for a basement egress window, generally does.

Verify with: Your municipal building department confirms what your specific job requires.

ENERGY STAR certification for the product

Relevant if you intend to claim any efficiency rebate, which typically requires certified products and documentation.

Questions worth asking

Is this a retrofit or a full-frame installation? What would the other one cost?
How is the gap between the window and the rough opening insulated and air-sealed?
Is exterior capping included, and in what colour and material?
Is the warranty on the glass seal, the frame, and the labour - and are they different lengths?
Is the warranty transferable if I sell the house?
