Behind the wall
Our shower valve replacement coverage in District of Columbia runs to 277 ZIP codes in 4 cities.

What this site is
ShowerValve is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and valve work opening a wall is often a permitted alteration — ask to see the permit. We carry out no work, we sell no valves, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call. The maximum water temperature is set by your local code, not by this website.Checking a credential in District of Columbia

What that coverage looks like
Washington, at 265 ZIP codes, is the largest part of our District of Columbia footprint, and District of Columbia County holds 271 of the 277 we cover. A valve job needs the right cartridge in the van, so the call asks what the trim looks like and how many handles it has before anyone is sent.
How a shower valve replacement job goes
A shower that will not hold temperature is a cartridge far more often than it is a valve. The cartridge sits inside the valve body behind the tiles and can usually be drawn out through the trim plate without opening the wall. The wall comes off when the body itself is cracked, seized into the pipework, or no longer made in a form that fits.
What the call asks about shower valve replacement
- How many handles the shower has, and whether the trim plate is round or square.
- Whether the fault is temperature, pressure, or a drip that will not stop.
- The maker if it is stamped on the trim, because that identifies the cartridge.

Before you call
A valve that will not hold temperature is a cartridge far more often than it is a valve. The pages above say how to tell before the tiles are touched.
