Signs the valve needs attention
- The shower head drips after the handle is fully off
- The temperature swings when a toilet flushes
- The handle is stiff or turns too far
- Weak flow even though other fixtures are fine
- Water staining on the ceiling below the shower
Why showers wear out here
Hard water leaves deposits inside cartridges, and rubber seals harden. Many Scarborough homes built before the 1990s have older single-handle valves without modern pressure balancing. Bathroom renovations over the years have also left a mix of brands, so identifying the exact valve is the first job.
Find the brand: Look for a name on the handle or trim plate. It helps us bring the right cartridge.
How we fix it
- The water is shut off and the handle and trim are removed.
- We identify the valve and inspect the cartridge or stems.
- Worn parts are replaced and the valve body is cleaned.
- If the valve is obsolete, we discuss replacing it through an access panel.
- The shower is tested for drips, temperature control and flow.
What affects the price
Common valves with parts available are quick. Seized or discontinued valves may need replacement, which can involve tile work.
