Burst and Frozen Pipe Repair in Houston, TX
Houston rarely freezes hard, which is exactly why its pipes are vulnerable: water lines are often run through the attic with little insulation. In the February 2021 winter storm, attic and exterior-wall pipes froze across the region and split as they thawed. If a pipe bursts, shut off the main at the meter or house valve first.

What is different about burst and frozen pipe repair in Houston?
A burst in the attic is the worst place for one. Water comes through the ceiling, soaks insulation and drywall, and can run for hours if no one is home. Know where your shutoff is before a freeze: many Houston homes have a valve on the main where it enters the house, and all have a shutoff at the meter box near the street, which may need a meter key.
During a freeze warning, the standard local advice applies: wrap outdoor faucets, open cabinet doors on outside walls, let faucets drip, and if the power and heat go out, shut off the main and drain the lines. After a repair, ask about insulating attic runs or replacing damaged sections with pipe that tolerates freezing better.

Freeze breaks in attics
During the February 2021 winter storm, pipes in attics and exterior walls froze across the region and split when they thawed. Insulating attic lines and knowing where the main shutoff is matters more here than people expect.
What to check and ask before work starts in Houston
- Ask the plumber to check the rest of the attic piping for splits that have not leaked yet
- Ask what insulation or rerouting would protect the line next time
- Ask to be shown where your main shutoff is and whether it works
- Photograph the damage before repairs for your insurer

Burst and Frozen Pipe Repair questions from Houston
Why do Houston homes have water pipes in the attic?
Homes are built on slabs, and because the ground rarely freezes, builders often route water lines overhead instead of under the concrete. It makes repairs easier but leaves the pipes exposed in the occasional hard freeze.
Should I turn off my water during a Houston freeze?
If you lose power and heat, or will be away, yes: shut off the main and open the lowest faucet to drain the lines. If the heat is on, dripping faucets and opening cabinets on outside walls is usually enough.
