A leaking shower might be a failed pan, a gap in the wall waterproofing, a loose drain connection, bad caulk, a door that sprays past the curb or a supply pipe in the wall. Each needs a different repair, and guessing gets expensive.
We diagnose leaks methodically for homeowners and condo owners across Northern Virginia, and explain what we find in plain terms.
How We Find the Leak
Each test isolates one part of the shower.
- Visual check: caulk, grout, corners, the curb, the door sweep and the valve trim
- Drain test: water run straight into the drain, bypassing the pan, to test the trap and connection
- Pan flood test: drain plugged and pan filled, to test the pan and curb
- Wall spray test: one wall wetted at a time, working upward
- Supply test: checking whether the leak appears with the water on but no one showering
- Moisture readings on adjoining walls and the ceiling below
Typical Causes and Fixes
Failed caulk and grout are the best news: recaulking and regrouting are quick and inexpensive. A leaking valve or pipe is a plumbing repair, often reached from the wall behind. A drain that has come loose from the pan can sometimes be resealed.
A failed pan or missing wall waterproofing cannot be fixed from the surface. Those need the affected section rebuilt: see shower pan installation and shower remodel.
Leaks in Condos
If water is reaching the unit below, act quickly and tell your building management. We can provide a written description of the cause and the repair for your association or insurer, and coordinate access with your neighbor when the ceiling below needs to be inspected.
