📞 (905) 261-9082TDC Contracting handles electrical and plumbing rough-in as an integrated part of kitchen, bathroom, and basement renovations. This means the wiring runs, circuit additions, outlet and switch rough-in, and plumbing supply and drain work that happens before walls close — coordinated with the rest of the renovation scope so you do not need to manage separate trades.
Note: Complex electrical panel upgrades or major plumbing system changes may require coordination with a licensed electrician or plumber. We assess the scope of your specific project and advise on what applies during the quoting process.
Electrical wiring runs and plumbing supply and drain lines are installed inside walls, floors, and ceilings. Once drywall is up, these systems are no longer accessible without cutting into finished surfaces. Getting the rough-in right — in the right locations, to the right specifications, and inspected before walls close — is what makes the rest of the renovation work cleanly. Changes after drywall means cut walls, patched drywall, and redone finishes.
When framing, electrical, plumbing, insulation, and drywall are all managed by one team, the sequencing is handled correctly by default. Electrical rough-in happens after framing and before insulation. Plumbing is roughed in and inspected before walls close. Drywall does not go up until everything that needs to be behind it is done and approved. Managing multiple separate trades requires the homeowner to coordinate this sequencing themselves — which creates real risk if one trade is not ready when the next one arrives.
Electrical and plumbing work in Ontario generally requires permits and inspections. The specific requirements depend on the scope and the municipality. We walk you through what applies to your project during the quoting process so permits are arranged before work begins and inspections are scheduled at the right stages.
Electrical and plumbing rough-in is scoped and quoted as part of the overall renovation — kitchen, bathroom, or basement — so you receive one clear quote covering the full scope rather than assembling costs from multiple trades separately.
After framing is complete, electrical and plumbing rough-in is installed before insulation and drywall. We coordinate inspections at the appropriate stages so the project progresses without delays caused by sequencing issues.
Once finishes are in, fixtures are connected and tested. Outlets, switches, lights, faucets, and drain connections are completed as part of the final stage of the renovation.
Rough-in electrical refers to the wiring runs, junction boxes, and circuit connections that happen inside walls before they are closed. Finish electrical is the installation of devices — outlets, switches, fixtures — after drywall and paint are complete. Both stages are part of our renovation scope where electrical work is included.

Relocating plumbing fixtures is a common part of kitchen and bathroom renovations. What is involved depends on where the existing supply and drain lines are, where the new fixture needs to go, and what changes to the drain and vent system are required. We assess this during the quoting process and include it in the scope where it applies.
