Professional Water Leak Repair in Houston

A dripping faucet is easy to spot. The leaks that do the most damage are the ones you never hear: a pinhole in a copper line behind the drywall, a failed connection inside a vanity, or a supply line leaking under the slab. By the time a stain or soft spot appears, water may have been soaking into your home for weeks.

Nick's Plumbing & Air Conditioning has provided water leak repair in Houston since 1979. We find the source, stop the water, and make a lasting repair, so a small leak does not turn into drywall, flooring, and mold remediation bills.

Warning Signs of a Hidden Water Leak

Most water leaks happen behind walls, inside cabinets, under floors, or below the slab. Watch for these signs:

• Water stains or bubbling paint on walls and ceilings
• Damp, warped, or soft flooring and baseboards
• Musty odors, mildew, or mold growth
• Lower water pressure at sinks and showers
• A water bill that jumps with no change in usage (see why your water bill spikes and what to check first)
• The water meter moving when every fixture is turned off
• Soggy or unusually green patches in the yard

A leaking supply line is under constant pressure, so it can release several gallons an hour into a wall cavity. If you notice any of these signs, it is worth having the plumbing checked before the damage spreads.

Where Water Leaks Hide in Houston Homes

Bathrooms

Worn flappers and fill valves let water run from the tank into the bowl nonstop. You may hear a hiss, or you can add a few drops of food coloring to the tank: if the color shows up in the bowl without flushing, the tank is leaking. A rocking toilet or water around the base usually means a failed wax ring or broken flange, which lets wastewater into the subfloor. Do not just mop it up. Learn more about our toilet repair service.

Kitchens and Vanities

Supply lines, shutoff valves, and drain connections under sinks can drip for days without anyone noticing. Check under every sink regularly for moisture, and look for swollen or stained cabinet floors. A drip at the spout wastes water too, and our faucet repair service can fix it.

Around the Water Heater

Tank water heaters typically last 7 to 10 years. As they age, sediment and corrosion break down the tank from the inside. Leaks at fittings and valves can often be repaired, but once the tank itself is leaking, replacement is the only fix. We handle both water heater repair and water heater replacement.

Under the Slab Foundation

Most Houston homes are built on concrete slabs with water and drain lines running underneath. A leak there can wash out the soil, leading to cracked walls, uneven floors, and doors that stick. Warm spots on the floor, the sound of running water, or constant dampness are red flags. For suspected drain leaks, we use hydrostatic leak testing to confirm the problem before any concrete is cut.

Water and Sewer Lines

The main water line from the meter and the sewer line leaving the house both run underground, where leaks are impossible to see. We offer water line repair for supply problems and camera-based sewer leak detection to find cracks, breaks, and root intrusion.

How We Repair Water Leaks

1. Locate - We trace the leak to its source with a minimum of wall or floor openings
2. Explain - We show you what we found and give you clear repair options and pricing before work begins
3. Repair - We fix or replace the damaged pipe, fitting, or fixture with quality materials
4. Test - We restore water and confirm the repair holds with no further leaks

If your home has aging galvanized or copper pipes with repeated pinhole leaks, patching one spot at a time may not be the best value. In that case, we will talk with you about whole-home repiping. To catch future leaks early, ask about the Flo leak detection system, which can alert you and shut off the water automatically.

Water Leak Repair Cost in Houston

Water leak repair at Nick's Plumbing starts at $325, with most repairs falling in the $325-$1,700 range. Cost depends on where the leak is, how much access is needed, and the type and age of the pipe.
