## Which shutoff needs help?
01 One fixture at a time
### Sink, toilet & appliance valves
Leaking under the sink? Toilet valve won’t close? Start with the small valves feeding one fixture.

02 The whole home
### Main water shutoffs
Find your house main, see inside ball and gate valves, and know the outside emergency backup.
Explore main shutoffs & 3D →
03 When you’re away
### Automatic leak shutoffs
Want protection while you’re away? Compare water-use monitoring with leak sensors.

**Water leaking right now?**
Close a working valve ahead of the leak. If the house main won’t stop it, call your water provider for an emergency outside shutdown. Keep clear of standing water near electrical equipment.

What a service visit covers
## A shutoff that stops water. And stays dry.
1. ### Plan the shutdown
We identify the valve, pipe material and working shutoff ahead of it. Replacing the home’s main may require a water-provider shutdown. In a shared building, we coordinate the interruption with the person managing the water supply.
2. ### Repair or replace the assembly
With the water isolated and pressure relieved, we service the matching internal parts or fit a replacement valve. We support the pipe and correct damaged nearby connections so the new valve has a sound base.
3. ### Test both jobs
We restore water gradually and check the body, stem and joints for leaks. Then we close the valve and verify that it stops the downstream supply. Finally, we reopen it, check flow and leave the handle reachable.
A few useful answers
## Common questions.
### Can you repair a leaking shutoff instead of replacing it?
Yes, when the body and sealing surfaces are sound and the correct service parts are available. Packing or a washer may solve a serviceable valve’s leak. A valve that is cracked, heavily corroded, seized or unable to shut off often needs replacement.

### Do both valves under a sink need replacing?
We check both. When they are the same age and both are stiff, leaking or unreliable, replacing the pair can save a second shutdown. A sound valve can stay when the problem is confined to the other side.

### What affects the cost of shutoff-valve replacement?
The valve type, pipe condition, room to work and method of shutting off the supply drive the job. A reachable fixture stop takes different work from a main valve inside a finished wall. Smart shutoffs add device selection, power, app setup and testing. We explain the scope and price before starting.

The price, in plain terms
## What does the price cover?
1. 01 **Name the work.** What's being repaired or installed, and what stays.
2. 02 **Check what's included.** Parts, labor, access, cleanup and any required permit.
3. 03 **Settle the open questions.** Extra work, exclusions and the warranty for this job.
A quote for shutoff valve work should make the scope clear. Check who handles access and patching, whether any further diagnosis costs extra, and what happens if opening things up reveals more damage.
**Found a lower number? Ask us why ours is different.** Bring both descriptions of the work. Compare the equipment, repair scope and exclusions before deciding what the difference buys. A higher price alone doesn't prove a better job.

Shutoff Valves
### Find your main shutoff before you need it. The valve in the yard probably isn't it.
Along the Wasatch Front the capped valve in your lawn is almost always the sprinkler shutoff, not the house shutoff. And the real one has a habit of leaking the first time it's turned in twenty years.
