How it works

Confirm the diagnosis

We lift the lid, observe the fill and drain cycle, and check whether the flapper, fill valve, or float is responsible for the running water.

Replace the flapper

We shut off the supply, flush the tank empty, unhook the old flapper, and snap on the correct replacement, adjusting the chain to the right length.

Test and confirm

We open the supply valve, let the tank fill, and listen and look to confirm the running has stopped and the flush is clean.

We can help

Problems we fix

Toilet that runs for 30–60 seconds after every flush — a flapper not seating fully
Toilet that runs continuously because the flapper has hardened or cracked
Wrong-size replacement flapper installed, causing the same leak to continue
Chain too short, holding the flapper off the seat permanently

Good to know

Toilet Flapper Replacement in Charleston — FAQ

Can I diagnose this myself before calling?

Drop a few drops of food coloring in the tank without flushing. If color appears in the bowl within a few minutes, the flapper is leaking. That's your confirmation.

What if the flapper replacement doesn't stop the running?

If the seat (the surface the flapper rests on) is pitted or warped, a new flapper still won't seal. In that case, a full flush valve replacement fixes the problem — we assess and recommend on the spot.

Is a running toilet urgent?

Not a safety emergency, but a running toilet can waste several hundred gallons a week. It's worth addressing promptly — the fix is fast and inexpensive.

Local context

Toilet Flapper Replacement 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.
