How the job is handled
Current shower mixers rely on either a pressure-balancing or a thermostatic cartridge. We identify the brand and replace or service the cartridge. Older two- and three-handle valves need stems, washers and seats. If the valve body is obsolete or corroded, replacement through an access panel or tile opening is planned carefully.
We set the rotational limit stop to help prevent scalding.
If you are renovating, consider a thermostatic valve for precise temperature control.

Local card: Whitby houses
Scale from harder water can cause cartridges to stick. Homes with softeners tend to see longer cartridge life.
