A plumbing rough-in lays out the supply lines, drains, and vents inside your walls and floors, before drywall or flooring goes down. It has to be right the first time, and it has to pass inspection. Our York team (headquartered at 554 Caledonia Rd) works directly with your contractor or architect, with a free estimate based on your plans. Call (289) 233-7221.

Not sure which one you need? Call us — we’ll walk you through it over the phone before booking anything.

Send us the layout and we'll price it before any work starts.
