Why us

We know construction has a bad reputation

Look, we get it. Construction has a bad reputation, and honestly? A lot of it is deserved. There are guys out there who'll promise you the moon, take your money upfront, and then you're chasing them for months wondering if they're ever coming back. We've heard the stories. We've fixed the messes. And we built our entire way of working around making sure that's never your experience with us.

We don't take a dollar until we actually show up and start working. Everything — and I mean everything — goes on paper before we begin. What we're building, what materials we're using, how long it'll take, what it'll cost. No "we'll figure it out as we go." No surprises halfway through.

We've been doing this for over 25 years, and here's what we've learned: the work we do is going to be in your home for a long, long time. Decades, probably. The last thing we want is to build something that becomes a source of regret — for you, yeah, but honestly for us too. Every project we take on, we take personally. This isn't just our business. It's our craft. It's what we've dedicated our lives to.

That's why we offer 5 to 10 year warranties depending on the project. That's why we answer our phones. That's why we don't disappear. Because we're not just trying to get through your project — we're trying to build something we're both proud of.

What sets us apart

Clear Communication

Local Expertise

We know GTA homes — the housing stock, the soil conditions, the permit process. That local knowledge makes a difference.

Stand Behind Our Work

We offer real warranties and we're here for the long term. If something's not right, we make it right.

Frequently asked questions about Buildoreno

Buildoreno's principals have over 25 years of combined GTA construction experience. Founder Chris Grygoruk spent more than two decades as a trusted subcontractor for major GTA general contractors before launching Buildoreno to serve homeowners directly. The company currently operates as an Ontario-registered corporation headquartered in Mississauga.

Buildoreno is headquartered in Mississauga, Ontario. We serve homeowners across the Greater Toronto Area within approximately 75 km of our office: Toronto, Mississauga, Brampton, Vaughan, Oakville, Markham, Richmond Hill, Burlington, Hamilton, Oshawa, Pickering, Ajax, Whitby, Newmarket, Aurora, Milton, Caledon, King City, Halton Hills, and Stouffville.

Buildoreno is owner-operated by founder Chris Grygoruk. The company is structured to keep ownership directly involved in every project — Chris reviews scope, Patrick Grygoruk manages projects and client communication, and the same team that quotes your work is the team that builds it. There are no sales reps disconnected from execution.

Buildoreno specializes in residential exterior renovation work that requires real expertise and proper engineering: metal roofing (standing seam, metal shingles, commercial), flat roofing (TPO, EPDM, modified bitumen), landscaping and hardscaping (interlock, retaining walls, drainage), underpinning (basement lowering, bench footing, foundation repair, basement apartments), and general contracting (kitchen, bathroom, basement finishing, additions, second-storey builds). We deliberately do not take on small handyman work, plumbing, electrical, or HVAC — we engage licensed subcontractors for those specialty trades when projects require them.

Yes to both, and yes — we encourage verification. Buildoreno carries $5 million in commercial general liability insurance, current WSIB Clearance, and is registered as an Ontario corporation. We provide Certificates of Insurance, WSIB Clearance Certificates, and corporation registration documents to any prospective client within one business day of request. See /certifications-licenses for full detail on every credential we maintain.

Submit our contact form or call (647) 254-0877. Patrick handles all initial inquiries personally and responds within one business day. For straightforward projects (roof replacement, standard landscaping, basement finishing), expect a written quote within 3-5 business days of an on-site assessment. For complex structural work (underpinning, additions, second-storey), the quote process takes 2-4 weeks because it requires structural engineering input. All estimates are free with no obligation.
