How it works
Drain and access internals
We shut off the supply, flush the tank empty, and sponge out remaining water to work cleanly.
Replace all tank components
We remove the old fill valve and flush valve, install new units of the correct type and height, and connect the supply line.
Adjust and test
We set the fill level to the correct line, adjust the chain to the right tension, turn on the supply, and run multiple flush cycles to confirm the tank fills, seals, and stops running cleanly.
Problems we fix
- Toilet that runs intermittently throughout the day — usually flapper combined with a failing fill valve
- Weak flush that doesn't clear solids — often a cracked or warped flush valve seat
- Tank that takes several minutes to refill — a fill valve with reduced flow from mineral buildup
- Phantom running (tank refills briefly on its own) — classic flapper leak into the bowl
Toilet Tank Rebuild in Charleston — FAQ
Is a tank rebuild worth it vs. just buying a new toilet?
For a toilet that's otherwise in good shape — no cracks, solid connection to the floor, acceptable water efficiency — a full rebuild extends its life significantly for far less than the cost of a replacement unit and installation.
Will rebuilding fix a toilet that needs to be flushed twice?
Usually yes. A weak or incomplete flush is often a combination of a low fill level, a degraded flush valve, or a flapper that doesn't stay open long enough. A rebuild addresses all three.
How long does a tank rebuild take?
Typically 45–60 minutes. We drain the tank, swap all three components, make adjustments, and confirm it's working before leaving.
Toilet Tank Rebuild across Charleston
Charleston's humid subtropical climate, salt air and active storm season are tough on homes — swollen doors, rusting hardware, mildew-prone caulk and storm-loosened trim are all common. Downtown's historic houses add original plaster walls and tight, detailed millwork, while West Ashley and the islands bring newer builds with their own quirks. Our pros are comfortable with both.
