Water Service Upgrades for Garden Suites, Multiplexes and Busy Homes

Adding a garden suite, a basement apartment or extra units puts more demand on the pipe that brings water into your home. We size and install a service that keeps up, usually with very little digging.

Are you planning a garden suite, a basement apartment or a full multiplex conversion? One of the first things to check is the pipe that brings water into your home. Many older houses in Toronto, Mississauga and Oakville still run on the small service line they were built with, and that line was never meant to supply two or three households at once.

We offer water service upgrades that are sized for the home you are building, not the one you had. Our team looks at every fixture you plan to add, works out the flow the property needs, and installs a line that delivers steady pressure to every unit.

Why service size matters for garden suites and multiplexes

When several people use water at the same time, a small service line simply cannot move enough water. The result is weak showers, slow-filling tubs and appliances that take longer to run. In a rental unit or a multi-generational home, that quickly becomes a daily frustration for everyone.

Permit reviewers and designers often ask for a service sizing when new units are added. We can provide the sizing and install the line, so your project keeps moving and your tenants or family members get water pressure they can rely on.

Trenchless water service upgrades

Replacing a water service used to mean a long trench across the front yard. With our own trenchless equipment, we dig one small pit near the property line and one at the foundation, then pull the new line through underground. It is faster, cleaner and far less disruptive to your landscaping.

Some properties still need a short open trench, for example where rock, old foundations or tight clearances get in the way. We tell you before the work starts and list any restoration in your quote.

A cost-effective way to plan ahead

If you are already renovating, upgrading the water service at the same time is often the most cost-effective choice. The permits, the digging at the foundation and the interior connections can all be handled in one visit. We give you a written, itemized estimate so you can see exactly what the upgrade costs and plan your budget with confidence.

Know the signs

Signs your water service is too small

  • Pressure drops when a second shower, the dishwasher or the washing machine runs
  • You are adding a garden suite, laneway suite, basement unit or converting to a multiplex
  • Your home still has its original 1/2-inch service line
  • Your architect, designer or permit reviewer has asked for a water service sizing
  • You are adding a second bathroom, a larger kitchen or an irrigation system

Our approach

How we upgrade your service

Sizing based on your fixtures

We count the fixtures in the finished home, including any new units, and size the line to match the demand rather than guessing.

Trenchless installation where possible

With our own trenchless equipment we pull the new line through between two small pits, so your lawn, driveway and landscaping stay largely intact.

Coordination with the City side

When the public side also needs a larger pipe, we explain the municipal process and plan our work around it so you are not left waiting.

Permits and inspection

We pull the plumbing permit and book the inspection, then connect and test the new service before we close up.

Pricing

What affects the cost of water service upgrade

Every property is different, so we quote after we inspect. These are the factors that move the price up or down.

  • The length of the run from the property line to your water meter
  • Line size, pipe material and the number of units being served
  • Whether trenchless installation is possible or open excavation is needed
  • Driveways, walkways, retaining walls and mature trees along the route
  • Work needed at the foundation wall, meter and main shutoff inside the home
  • Whether the municipal side also has to be upsized or replaced

Rebates that can lower your cost

Toronto Priority Lead Water Service Replacement Program

The City replaces its side of a lead service on a priority basis once you commit to replacing your side. We replace the private side and give you the invoice the City asks for.

Amounts from official program pages. We prepare the paperwork for you.

Our process

How we work

Every job follows the same six steps, so you always know what happens next and what it costs.

  1. Camera first

    We look inside the pipe or trace the line before anyone talks price, so the quote is based on what is really there.

  2. Written quote

    You get an itemized estimate in writing, with the rebates that apply and your cost after them.

  3. Permits booked

    We pull the plumbing or building permit and book the inspections with your municipality.

  4. Low-dig work

    Where the ground allows, we use trenchless methods to replace pipe through small access pits.

  5. Restoration

    We backfill, compact and tidy the site. Any concrete, sod or finish restoration is listed line by line in your quote.

  6. Rebate filing

    We prepare the invoices, photos and permit proof your rebate application needs.

FAQ

Water Service Upgrade questions

Straight answers to the questions homeowners ask us most. If yours is not here, give us a call.

How do I know what size my current water service is?

Look at the pipe where it comes through your basement wall before the meter. We can confirm the size and material during a visit, and we note it on your written estimate.

Does a garden suite need its own water service?

Many garden suites are fed from the main house, which is why the main service often needs to be larger. We size the line for the combined demand of both buildings and explain the options that fit your permit drawings.

Will you have to dig up my whole front yard?

Usually not. In most cases we replace the line trenchless through one pit near the property line and one at the house, then backfill and tidy the site.

Can you upgrade the service and replace a lead pipe at the same time?

Yes. If your existing service is lead, the upgrade replaces it with new pipe, and in Toronto the City can replace its side through its priority lead replacement program.
