Residential New Construction Plumbing

Licensed Plumbing Rough-Ins & Finish Installs for New Homes Across Orillia & North Bay

Building a Home? Bring in the Pros From Day One.

When you’re framing a new build, plumbing isn’t just pipes — it’s your home’s backbone.

Poly-B Plumbing partners with homeowners, builders, and contractors to deliver clean, code-compliant installations that stand the test of time.

We handle full-scope plumbing for new custom homes, cottages, duplexes, and additions — from underground rough-ins to final trim.

Our Process: New Build Plumbing, Done Right

  1. Site Review & Planning
     We meet with your GC or review your blueprints to plan the best layout based on grade, access, fixture load, and code requirements.

  2. Rough-In Stage
     We install your full system before insulation or drywall — drain-waste-vent (DWV), water supply, fixture stubs, and cleanouts.

  3. Pressure Testing & Inspection
     We test every line and coordinate with inspectors to keep your build on schedule.
  4. Finish Plumbing
     Once drywall and flooring are in, we install faucets, toilets, tubs, and all other visible components.
  5. Final Walkthrough
     We test every fixture, check for leaks or pressure issues, and walk you through your new plumbing system.

Frequently Asked Questions

How long does it take to rough-in a home?

Most standard builds take 2–5 days for rough-in, depending on size and access. We coordinate closely with other trades to minimize delays.

Can you handle well and septic installs too?

Yes. We’re licensed in both and can coordinate with your driller or septic contractor to ensure everything is connected correctly and to code.

What materials do you use?

We install PEX, copper, ABS, and PVC — based on what’s best for your system, climate, and budget. No SharkBite or push-to-connect. Only high-performance parts.
