The 1920s and 1940s semis and bungalows running the Danforth corridor from Greektown to Woodbine are some of Toronto's most-loved family homes — and their bathrooms often need a thorough, skilled rebuild to match. Kopman Build has been doing exactly that work, in exactly these homes, since 1999.
Danforth Village's prewar semis and bungalows are full of character — and full of the challenges that come with age. Original galvanized plumbing, cast-iron drain stacks, deteriorated subfloors, and knob-and-tube wiring lurking behind bathroom walls are the norm, not the exception. A contractor who doesn't know what they're looking at will tile over these problems. We don't: we identify them upfront, price them honestly, and resolve them properly before a single tile goes down.
This neighbourhood is also deep in family renovation territory. Second-storey additions on Danforth bungalows — and the primary ensuites or full second bathrooms that come with them — are a major part of what we build here. We manage that scope alongside any kitchen opens or main-floor restructuring, coordinating every trade under a single contract with one point of accountability.
Dustin Kopman founded the company in 1999 after coming up through his family's construction firm. That background means projects here are managed by someone who understands the craft of working in older Toronto housing stock — not just the sales process.

In Danforth Village, bathroom renovation costs reflect the neighbourhood's 1920s–1940s semi-detached and bungalow stock: powder rooms $18,000–$40,000; main bathrooms $30,000–$70,000; primary ensuites $50,000–$150,000+. Older homes often carry hidden costs — galvanized plumbing, knob-and-tube wiring behind walls, and deteriorated subfloors — which we identify upfront so there are no surprises mid-project.
City of Toronto permits are required any time plumbing is relocated or structural changes are made to bathroom walls. In Danforth Village semis and bungalows, it's common to open walls for plumbing upgrades from original galvanized or cast-iron pipe — which does trigger a permit. We manage all applications and inspections as part of our standard process.
Yes — and it's one of the most common scopes we manage in this neighbourhood. A second-storey addition on a Danforth bungalow is an ideal opportunity to add a primary ensuite or a full family bathroom above. We coordinate the structural, plumbing, and finish work across both the addition and any related main-floor renovations simultaneously.
Homes built along the Danforth corridor in the 1920s and 1930s frequently have original galvanized steel supply lines and cast-iron drain stacks that are near or past the end of their service life. We assess existing plumbing at consultation and include a clear recommendation in the estimate: selective replacement of failing sections, or a full replumb if warranted. Proceeding without addressing deteriorated plumbing is a false economy — we won't tile over a problem.
