About Us
Ontario's trusted window, door and masonry contractor
Since 2016, Trust Build has helped thousands of Ontario homeowners replace windows, install doors, add blinds and complete masonry projects — all with factory-trained crews, transparent pricing and a lifetime product warranty.
Our Story
Built on referrals, not advertising
Trust Build started with a simple idea: homeowners deserve the same quality of installation that builders expect on new construction. Too many replacement projects were being handed to subcontractors who rushed through openings, skipped flashing details and disappeared when issues appeared months later.
We built a different model. Every installer is a full-time employee trained directly by the manufacturers we represent. Every project gets a dedicated project manager who measures, quotes and follows the job through final walkthrough. And every product carries a lifetime warranty backed by us, not a third party.
Today, more than 80% of our business comes from referrals and repeat customers. That is the only metric that matters.

Why Homeowners Choose Us
Four principles that guide every project
Transparent pricing
The price we quote is the price you pay. No hidden fees, no surprise charges after install. Every estimate is itemized line by line.
On-time delivery
We book a start date and we stick to it. If weather or supply delays arise, we communicate early — never the morning of.
Factory-trained crews
Our installers are employees, not subcontractors. They train directly with the manufacturers we represent and follow written installation protocols.
One crew, one warranty
We handle windows, doors, blinds and masonry in-house. That means one point of contact and one comprehensive warranty across every trade.
Service Areas
We install across the GTA and beyond
From downtown Toronto to Barrie and from Hamilton to Oshawa, our crews travel to your home with the same tools, products and standards.
