Complete Home Plumbing Projects: From Planning to Installation

Published July 2, 2026 · Installations & Upgrades · Mountain Grove Plumbing & Drains

A complete home plumbing project — a repipe, a renovation rough-in, a water heater and softener package — succeeds or fails in the planning stage. The installation itself is the visible part, but by the time pipe is being cut, every important decision has already been made. Here's how we run whole-home projects for Burlington homeowners, from the first walkthrough to the final pressure test, and what you should expect from any contractor doing this work.

Phase 1: Planning

The Inspection Comes First

Before anyone quotes anything, the existing system needs a proper look: supply material and condition, drain material and slope, water pressure at fixtures, the state of shutoff valves, and the water heater's age and capacity. In houses built before the 1980s — common across central Burlington and Aldershot — we regularly find galvanized supply lines, non-standard drain connections from past DIY work, and shutoff valves that haven't been turned in decades and won't close.

A quote written without this inspection is a guess. Guesses become change orders.

Permits in Burlington and Halton

Most plumbing alterations — moving fixtures, changing drain configurations, replacing water heaters in some configurations — require a plumbing permit from the City of Burlington. The permit isn't bureaucratic overhead; it means an independent inspector verifies the rough-in before walls close. For homeowners, this matters twice: once for safety, and again at resale, when unpermitted plumbing work can complicate a sale. A legitimate contractor handles permit applications as part of the project scope. Be wary of anyone who suggests skipping it.

Fixture and Material Selection

Decide fixtures early, because rough-in dimensions depend on them. A wall-hung vanity, a freestanding tub, and a curbless shower each place drains and supplies differently. The same applies to materials: PEX and copper both do the job for supply lines, with different trade-offs in cost, freeze tolerance, and installation speed. We'll recommend based on your house, but the decision should be made — and priced — before the project starts, not during it.

Phase 2: Common Whole-Home Project Types

The projects we most often scope as complete packages for Burlington homes:

• Supply repipes — replacing galvanized or Poly-B lines throughout the house, usually the highest-urgency project when those materials are present.
• Bathroom and kitchen rough-ins — the plumbing phase of renovations, coordinated with your general contractor. See our bathroom services and kitchen services pages for what each typically involves.
• Water heater system upgrades — tank replacement or tankless conversion, often bundled with a softener or filtration install while access is open.
• Main drain work — replacing or lining the building drain, usually after a camera inspection has found root intrusion or collapsed sections.

Phase 3: Sequencing Around a Renovation

If your plumbing project is part of a larger renovation, sequencing is where money gets saved or wasted. The order that works:

1. Demolition exposes the existing plumbing.
2. Plumbing rough-in happens while walls and floors are open — this is when drains move, supplies get run, and shower valves get set.
3. Rough-in inspection by the city, before anything closes.
4. Walls close, tile and finishes go in.
5. Fixture installation (finish plumbing) — toilets, faucets, shower trim — happens near the end, after surfaces are done.

The most expensive phone call we get is the one where the tile is already installed and the shower valve is in the wrong place. Bring the plumber in at the planning stage, not after demolition.

Phase 4: What Installation Days Look Like

For a typical repipe or multi-room project, expect:

• Water off during working hours, on every evening. We don't leave a family without water overnight. Phased work — one bathroom at a time — keeps at least one functioning bathroom throughout.
• Access openings. Runs through finished walls require cut openings. The scope should state up front who patches them — plumbing crews typically cut and rough-patch; finish drywall and paint are usually the homeowner's or GC's side.
• Daily cleanup and a walkthrough. You should know what was completed each day and what's next.

A full repipe on a typical two-storey Burlington home generally runs a few working days; a single bathroom rough-in usually fits within one to two. Timelines belong in the written scope.

Phase 5: Post-Install Checks and Warranty

Before a project is done, three things need to happen:

• Pressure testing. Supply work is tested under pressure before walls close — this is also what the city inspector wants to see.
• Fixture-by-fixture verification. Every fixture gets run, every drain checked for flow and leaks, every shutoff valve operated. You should watch this happen.
• Documentation. Permits closed, inspection reports in hand, and the labour warranty in writing. Keep these with your house records; they matter at resale.

Ask every contractor the same closing question: who do I call if something drips in eight months, and what does that call cost me? The answer should be "us, and nothing" — in writing.

Getting Started

Whole-home projects reward early conversations. If you're planning a renovation or your home still runs on original plumbing, start with an assessment of what's actually behind the walls — our plumbing services page outlines how we approach it. A clear scope, a fixed quote, and the right sequence turn a stressful project into a predictable one.
