Chevy Chase's housing is among the oldest in Montgomery County, with about 68 percent of homes in ZIP 20815 built before 1980, so shower valves are often decades-old units or replacements set into older walls. Most problems come from worn stems, seats or cartridges. Call the number on this page to be connected with a local plumber in Chevy Chase.

Signs to look for
- A dripping head that never quite quits
- Separate hot and cold handles that need hard cranking to stop the flow
- Water that turns hot or cold suddenly when another fixture runs
- Squealing or chattering pipes when the shower is on
- Loose tile, bubbled paint or stains on the ceiling below the bath
Hard cranking and chattering usually mean worn washers or seats. Sudden temperature swings mean the valve lacks, or has lost, its pressure-balancing feature. Damage below the bathroom is the most urgent sign.
What's local about Chevy Chase
Chevy Chase grew as an 1890s streetcar suburb along Connecticut Avenue, developed by the Chevy Chase Land Company with single-family houses, and today it's a patchwork: an unincorporated area plus several incorporated towns and villages such as the Town of Chevy Chase. That matters for approvals. WSSC Water Permit Services issues plumbing permits, Montgomery County's Department of Permitting Services issues building permits, and the Town of Chevy Chase has its own permits for larger construction and won't approve a town permit until the County permit is in place. A valve repair on its own rarely reaches that level, but a bathroom remodel can. WSSC Water supplies water and sewer service.
What affects the cost
- Rebuild or replace. Old valves from known makers can often be rebuilt; others can't.
- Wall construction. Plaster, mortar-set tile and vintage tile that can't be matched slow the work.
- Connecting piping. A new valve may need adapters or a short run of new pipe to meet older lines.
- Upgrades. Moving to a pressure-balancing or thermostatic valve adds parts and wall work.
- Approvals. WSSC for plumbing, plus County and town steps if the project grows.

The plumber will remove the trim, check the stems or cartridge, and explain whether a rebuild or a new valve makes more sense before any wall is opened.
