Leaks, pipes & freezing in Houston, TX
Pipe problems range from a burst line that needs the water shut off right now to slow pinhole leaks that show up as a high water bill. A licensed plumber finds where the water is escaping, repairs or replaces that section, and tells you whether the rest of the piping is likely to follow.

Leaks, pipes & freezing services in Houston
Burst pipe repair in Houston
UrgentTurn off the main water shutoff first, then open a faucet on the lowest floor to drain the lines. A plumber cuts out the split section, replaces it, and checks the rest of that pipe run, because one freeze rarely damages only one spot.
Frozen pipe thawing
UrgentIf a faucet gives no water or only a trickle after a hard freeze, a pipe is frozen. Leave that faucet open, warm the area gently, and call a plumber if you can't find the frozen section or if it's inside a wall, because a split pipe will leak as soon as it thaws.
Leak detection in Houston
Turn off every fixture and watch the water meter's leak indicator. If it moves, water is leaking somewhere. A plumber uses pressure tests, acoustic listening and thermal imaging to find the leak so only a small section of wall or floor has to be opened.
Repiping
Repiping replaces a home's water supply lines, usually because old galvanized steel has corroded or polybutylene is at risk of failing. Most repipes today use PEX, take two to five days, and are done through small wall openings rather than gutting the house.
Water line repair
UrgentThe water service line runs from the curb stop near the street to your house, buried below the frost line. A leak shows up as a soggy patch in the yard, low pressure throughout the house, or a meter that never stops. Repair means finding the leak, then fixing that spot or replacing the line.
Local conditions
Leaks, pipes & freezing in Houston: what's different
Houston's expansive clay swells in wet months and shrinks in drought, which stresses supply lines under slab foundations. Slab leaks, found by warm spots on the floor, the sound of running water or a rising bill, are one of the most common Houston plumbing calls.
Homes built for heat often have pipes in attics and exterior walls, so a rare hard freeze can split lines across the city at once. Permits inside city limits come through the Houston Permitting Center; unincorporated areas follow county and utility district rules.

Other Houston conditions that affect plumbing
- Shifting clay and slab leaks: Houston's clay swells in wet months and shrinks in drought, cracking cast-iron drains under slabs and stressing supply lines.
- Hurricane and flood season: Tropical storms and heavy rain can back up sewers and flood low-lying neighborhoods; backwater valves and clear main lines matter here.
- Rare hard freezes: Homes built for heat often have pipes in attics and exterior walls, so an occasional deep freeze can split lines across the city at once.
