About Us
Ontario's trusted window, door and masonry contractor
Last updated: August 1, 2026
Since 2016, Trust Build has helped thousands of Ontario homeowners replace windows, install doors, add blinds and complete masonry projects — all with our own crews and transparent pricing.
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 completed without enough attention to opening preparation, flashing details, or long-term service.
We built a different model. Trust Build’s own installation crews follow consistent installation standards. Every project gets a dedicated project manager who measures, quotes and follows the job through final walkthrough.
Today, more than 80% of our business comes from referrals and repeat customers. That is the only metric that matters.
You don't have to take our word for any of it. Our company facts and sources page pairs every claim we make with where you can check it — including our independent Better Business Bureau profile and HomeStars reviews. Full company details are set out on our company information page.

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.
Our Own Crews
Trust Build’s own installation crews follow written installation protocols and product-specific requirements.
One crew, one point of contact
Our own crews handle windows, doors, blinds and masonry — one team, one point of contact, from start to finish.
Service Areas
We install across Southern Ontario
From Toronto and the GTA to Simcoe County, Durham, Hamilton-Halton, Niagara, the London area, and Kawartha Lakes and Peterborough, our crews travel to your home with the same tools, products and standards — not just the areas closest to our head office.
