Some of the most damaging leaks in a home come from the cheapest parts — a hardened wax ring under a toilet, a cracked tank-to-bowl gasket, a dried O-ring in a faucet, or a compressed drain gasket under a sink. Seal and gasket repair replaces those small components before they rot a subfloor or a cabinet. A seal is a wear part by design: it stays flexible and watertight for years, then dries, hardens, or compresses until it weeps — and because the leak is often slow and hidden, it does its damage quietly until the floor around a {city} toilet feels soft.
The seal that leaks tells us where to look. A toilet weeping at the floor when flushed is a failed wax ring, and one leaking between the tank and bowl is the spud gasket and tank bolts; an under-sink drip traces to the drain gasket, the P-trap washers, or the supply-line seal; and a faucet leaking at the base or spout is an internal O-ring. We replace the specific seal with the correct part — a new wax ring and closet bolts set on a clean flange, fresh brass or rubber drain gaskets, or a manufacturer O-ring kit — and test the fixture under water before we call it done across {county}.
Reseating a toilet is the seal repair we do most, and doing it right matters more than it looks. A wax ring only seals if the flange is sound and at the correct height, the bolts are set square, and the bowl is shimmed level and not rocked afterward — a rushed reset weeps again in months. We check the flange, replace it or add a spacer if it's below the finished floor, set a new ring and bolts, and secure the bowl so the {areas} seal lasts. The same care goes into every gasket we touch in the {city} home.
Signs you need seal & gasket repair
Water pooling at the base of a toilet
Water appearing at the floor when you flush is a failed wax ring letting the seal weep. Left alone it rots the subfloor around the the United States toilet, so it's worth reseating promptly.

A toilet that rocks or shifts
A bowl that moves when you sit is breaking its wax seal with every use. Shimming it level and resetting the seal stops the slow leak before it damages the the United States floor.
Water between the tank and bowl
A drip from where the tank meets the bowl is a worn spud gasket or loose tank bolts. Replacing the gasket and bolts stops the leak on the your area toilet.
Drip under the sink at a connection
Water at the drain or supply connection under a sink is a compressed gasket or a dried washer. Reseating it with a new seal keeps the the United States cabinet floor dry.
Faucet leaking at the base
A leak seeping from the base of a faucet handle or spout is a hardened internal O-ring. A fresh O-ring kit reseals the the United States faucet before the water reaches the counter.
Common causes & what we fix
Hardened wax ring
The wax ring under a toilet dries and loses its seal over years, or breaks when the bowl shifts. A new ring on a sound flange restores the watertight seal in the the United States home.
Degraded O-rings
The rubber O-rings in faucets and valves harden and crack with age and hot water, letting water seep past. Replacing the O-ring kit reseals the the United States fixture.
Compressed drain and trap gaskets
Slip-joint and drain gaskets under a sink compress and dry until they weep at the connection. Fresh washers reseat the your area drain and stop the cabinet leak.
Worn tank-to-bowl gasket
The spud gasket sealing the tank to the bowl fails and the tank bolts corrode, dripping between the two. Replacing both stops the leak on the the United States toilet.
Failed flange or spacer
A closet flange that's cracked or sitting below the finished floor prevents the wax ring from ever sealing. We repair the flange or add a spacer so the seal holds in the the United States home.

Frequently asked about seal & gasket repair
Top questions homeowners searching for Seal & Gasket Repair near me ask us:
Why is water leaking around my toilet?
Water at the base when you flush is almost always a failed wax ring, often because the bowl rocked and broke the seal. We reset the toilet on a new ring and check the flange so the the United States seal lasts, not just weeps again in months.
Can you fix a leak between the tank and bowl?
Yes — that's a worn spud gasket and usually corroded tank bolts. We replace the gasket and bolts and reseat the tank so it seals to the bowl again on the the United States toilet.
How long does a seal or gasket repair take?
Most seal repairs run 30–60 minutes — reseating a toilet, replacing a drain gasket, or rebuilding a faucet O-ring. We test the fixture under water before finishing so the your area repair is confirmed dry.
Is a small seal leak really worth fixing?
Yes — a slow seal leak is cheap to fix and expensive to ignore, because the hidden water rots subfloors and cabinets over time. Replacing an inexpensive wax ring now beats a rotted floor around the the United States toilet later.
My toilet rocks — is that related to the leak?
Directly — a rocking bowl flexes and breaks its wax seal every time it's used. We shim it level, secure it, and set a fresh seal so it stops both the movement and the leak in your the United States home. We serve ZIPs .
