Many of the tubs we work on are original cast iron in 1950s capes and colonials, with three-handle valves whose parts are hard to find. We can often rebuild them, and when we cannot, we replace the valve with a modern pressure-balance unit without tearing out the whole wall.
Shower and tub problems we fix
- Shower head or tub spout drips after the handle is off
- Water comes out of both the spout and the shower head at once
- The shower scalds or goes cold when a toilet flushes or a washer fills
- Handle is stiff, spins freely, or will not shut off
- Tub drains slowly or the stopper no longer holds water
- Water on the ceiling below the tub after a shower
- Tub spout leaks behind the wall at the pipe connection
- Low or uneven flow from the shower head
Shower and bathtub services
Shower valve repair and replacement
Cartridges, stems and seats on single and multi-handle valves, or a full valve replacement when parts are gone. All major brands.
Pressure-balance and thermostatic valves
Modern valves that hold the shower temperature steady when someone flushes a toilet or runs the dishwasher. Required by code on new installs and a real upgrade on old three-handle setups.
Tub spouts and diverters
Replacing worn spout diverters that send water to both outlets, and repairing in-wall diverter valves.
Tub and shower drains
Overflow and drain assemblies, trip-lever and lift-and-turn stoppers, and drain lines that have separated under the tub.
Tub replacement rough-in
Setting the valve, spout drop, drain and overflow for a new tub or shower base during a remodel, at the depth the finished wall needs.
Shower heads, hand showers and trim
New trim kits, rain heads, slide bars and hand showers, with the right arm and flange so nothing leaks into the wall.
What a shower or tub visit looks like
- 1
Identify the valve
We pull the trim and identify the brand and model so we can bring the right cartridge or replacement valve.
- 2
Access without wrecking tile
Where a valve must be replaced, we work through the existing opening or from behind the wall whenever possible, and use an oversized trim plate to cover a slightly larger cut.
- 3
Firm price before work starts
Repair or replacement, quoted by the job.
- 4
Test hot, cold and drainage
We check temperature control, diverter operation and the drain and overflow for leaks before we leave.
