EFS Plumbing provides professional shut-off valve replacement for residential and commercial properties across Toronto and the GTA. We replace seized, leaking, or original-brass valves with modern quarter-turn ball valves — under-sink, behind-toilet, washing-machine, hose bib, and main building shut-offs. Every replacement is pressure-tested before we leave, and we coordinate water-off timing for main-building work so the disruption is as short as possible. Often paired with a faucet or toilet install since the water is already off.
Most fixture shut-off swaps are 30 to 60 minutes per valve on site. A standard residential under-sink or behind-toilet valve replacement runs $150–$250 per valve including labour, valve, and new supply line. Main building shut-offs and frost-free hose bibs run higher and are quoted before the visit.
Scope
What's included
- 01 Quarter-turn ball-valve replacement on fixture stops
- 02 Main building shut-off replacement (notice required to schedule water-off)
- 03 Washing-machine valve box replacement
- 04 Outdoor hose bib (frost-free model recommended)
- 05 Pressure-test of every replaced valve
- 06 Supply line replacement when paired with the valve swap
Process
How a project goes
- 01
Locate
Identify the valves that need swapping — most homes have at least one seized or weeping shut-off, and replacing them before they fail saves you a flood.
- 02
Schedule water-off
For main-building work we coordinate timing with you so water is off for as little of the day as possible.
- 03
Drain
Water off, lines drained at the lowest fixture so the work area stays dry.
- 04
Replace
Old multi-turn or compression valve cut out. New quarter-turn ball valve sweat-soldered or press-fit in, depending on the line.
- 05
Test
Water restored slowly, valve cycled through full open and closed, joint inspected for weeping over a full pressure cycle.
What you get on every job
Three things customers actually want to know before they call — none of which is "we work hard."
Three-month warranty on every job
If the same issue comes back inside three months — same drain, same fixture, same valve — the return visit is included. In writing on every invoice.
Quote in writing before any work starts
Every job is quoted in writing, with parts and labour itemized, before any work begins. The number you agree to is the number on the invoice.

Questions customers ask about shut-off valve replacement
-
01 How much does a service call cost?
A standard residential service call runs $250–$350, which covers the visit and a one- to two-hour repair. Larger work — camera-follow-up drain cleaning, multi-fixture installs, leak repair behind drywall — is quoted on site before any work starts, so the number you agree to is the number on the invoice.
-
02 Do you warranty the work?
Yes — three months on every job, residential and commercial. If the same issue comes back inside that window, the return visit is included at no charge. The policy is written on the invoice, applied without argument, and the same on a small repair as it is on a major project.
-
03 Are you licensed and insured?
Yes — licensed Ontario plumber, carrying liability insurance. Both documents are shown before the work starts on request. With we and a, licensing and insurance are baseline — not a feature to advertise, just the standard we work to on every residential, commercial, and emergency call.
