Running, Leaking and Clogged Toilet Repair in Houston

A running toilet can waste as much as 200 gallons of water per day, around 6,000 gallons a month, and add tens of dollars to a Houston water bill. Ignoring leaks, weak flushes, or water at the base only makes the problem more expensive.

Nick's Plumbing & Air Conditioning has provided toilet repair in Houston since 1979. Our licensed, background-checked technicians fix running tanks, leaking supply lines, worn flappers, loose handles, rocking bowls, and stubborn clogs so your bathroom is back in service fast.

Many toilet parts are inexpensive. Installing them correctly, and knowing when a deeper drain or flange issue is involved, is where a professional plumber saves you time and water.

Signs You Need Toilet Repair

Toilet problems rarely stay quiet. Call for service if you notice:

• A toilet that runs or hisses after every flush
• Incomplete flushes, or a toilet that will not flush at all
• Water puddles under the tank or around the base
• A loose flush handle
• A toilet that rocks side to side
• Gurgling sounds during or after flushing

Toilet Problems We Repair in Houston

Running toilet

A worn flapper lets water escape from the tank into the bowl, so the fill valve keeps cycling. A misadjusted float can also overfill the tank and send excess water down the overflow tube. Either issue wastes water around the clock. We replace or adjust the tank components so the toilet shuts off cleanly again.

Leaks under the tank or at the base

Puddles under the tank often point to a worn shutoff valve, a loose flex supply line, or tank-to-bowl connection issues. Water at the base can mean a failed wax ring or toilet flange. Left alone, moisture damages flooring and can let sewer odors into the bathroom. We tighten, reseal, or replace the parts that are actually leaking.

Clogged toilet

Simple clogs sometimes clear with a plunger. Deeper or denser stoppages need a powered drain snake or hydro jetting to restore proper flow. For drain-focused service, see our dedicated clogged toilet repair and drain cleaning pages.

Loose handle, rocking toilet, and flange repairs

Older flush handles can snap or wear out and need replacement, not a temporary bend. A toilet that rocks often means the flange or wax ring seal is compromised. We reset the toilet, replace the wax ring, and repair or replace the flange when needed so the seal stays tight.

Toilet Repair Cost in Houston

On this page's pricing guide, toilet repair typically starts around $200, with an average range of $200-$550, depending on brand and the work required. Flapper, fill valve, and handle jobs often land toward the lower end. Flange and wax ring resets, denser clogs, or combined leak and drain work can push higher.

Online averages are a planning guide, not a final quote. After we see the toilet, brand, and access, we confirm the cost before work proceeds. Financing is available when a larger repair or replacement makes sense.
