Caspian is the mechanical contractor for multi-unit residential developments across Toronto and the GTA — townhouse complexes, low-rise apartment buildings, and mid-rise condos. We deliver the full mechanical scope (plumbing, HVAC, hydronics) under one contract, run repeatable rough-in efficiently across many units, and cover both in-suite and common-area work. We're on site from first stack to final occupancy turnover, and we honour our work through the Tarion warranty period.
From in-suite rough-in to the central plant in the basement, Caspian carries the whole mechanical scope on a multi-unit development — so you're not coordinating three separate trades to get a single building closed.
Repeatable in-suite rough-in across every unit — supply, drain-waste-vent, in-suite hot water, HVAC trunk and registers. One crew, one drawing set, predictable production rate per unit.
Lobby washrooms, corridor hose bibs and janitor sinks, garage trench drains and oil interceptors, parking-level hose stations. Common-area scope priced in line, not as a change order.
Mechanical-room install of central boilers, domestic hot water plant, recirc pumps, and expansion. Hydronic distribution to in-suite fan-coils or radiant. Commissioned and balanced.
Vertical riser planning and install — domestic water, sanitary stacks, vent stacks, hydronic supply and return. Coordinated with structural and shaft layouts to avoid mid-project surprises.
We coordinate directly with the fire-protection sub on combined standpipe / sprinkler riser layouts, mechanical-room space allocation, and shared shaft routing. No clashes in the field.
Final unit-by-unit walk-throughs, deficiency list resolution, owner handover packages, and live coverage through the Tarion warranty period. One contractor — no scope finger-pointing.
Multi-unit margins live and die on production rate. We're built to run the same install across many units efficiently, without renegotiating the price or re-mobilising every block.
01 — Crew efficiency across many units
We deploy the right size team for the unit count — not too small to drag the schedule, not too large to burn hours. Once the in-suite layout is set, we move through repeatable rough-in block by block without renegotiating the price or scope at each phase.
02 — One PM, kickoff to occupancy
One project manager per development, from pre-construction kickoff through final occupancy. Same point of contact for permits, RFIs, the construction schedule, and the deficiency list — no handoffs between phases and no relearning the project.
03 — Documented inspection passes
Each unit's rough-in, top-out, and final inspection is tracked and documented through to occupancy. The records are the format your Tarion-relevant occupancy file expects — first-time pass rate is how we keep the schedule honest.
04 — Warranty period coverage
We honour our work through the full Tarion warranty period without finger-pointing about scope. If the owner calls in a mechanical deficiency, we go — no debating whether it's plumbing, HVAC, or someone else's sub. One contractor, one warranty obligation.
We scope and crew differently for each project size. Here's where Caspian fits across the multi-unit residential market in the GTA.
01 — Townhouse complexes
Repeatable plumbing + HVAC layouts across each block, shared utility connections, common drainage to street. Crew-sized for parallel production across multiple blocks at once.
02 — Stacked townhomes
Vertical stack riser planning between upper and lower units, garage-level mechanical and parking drainage. Coordinated trades sequencing on tight site footprints.
03 — Low-rise condo
Central plant in the mechanical room, riser coordination through shafts, full in-suite plus corridor and amenity work. Commissioning and balancing for handover.
04 — Mid-rise condo
Full mechanical scope — central plant, distribution, in-suite, common areas — with BMS integration and lifecycle planning for the property's first 25 years of operation.
