Burst pipe: what to do during a Friendswood freeze

Not every pipe in a Gulf-coast slab home faces the same risk in a hard freeze. Some rooms barely notice the cold. Others, the attic, an exterior wall, anything outside, take the brunt of it. Here’s where freeze damage actually starts, room by room, and what helps before and after.

The attic run has no insulation of its own

A supply line crossing the attic sits above the insulation, not under it. Insulation is laid to keep the living space warm, not the attic itself. During a hard freeze, that line sits closer to the outside air than to anything heated. Wrapping exposed attic pipe in foam sleeves before winter is cheap and takes an afternoon. Once a line up there splits, water usually shows up on the ceiling below before anyone climbs up to look.

An exterior wall isn’t as warm as the room it’s inside

A supply line run through an exterior wall sits between the siding and the drywall. It shares that wall cavity with whatever insulation the builder used, and that varies a lot by the home’s age. Older homes built before insulation standards tightened often have the thinnest protection here. Cabinets built against an exterior wall, especially under a kitchen or bathroom sink, are worth opening during a hard freeze. Warmer house air can reach the pipe inside that way.

The hose bib outside is the first pipe to go

An outdoor faucet has no wall around it at all, just a short run of pipe poking straight into the cold. Disconnect the garden hose before a freeze. A hose left attached traps water in the bib with nowhere to go. A foam faucet cover adds real protection for very little effort, and it’s the kind that costs a few dollars at any hardware store. A hose bib that’s already split usually shows it outside, as ice or a small drip along the pipe, not as an indoor flood.

Water heater connections sit exposed at floor level

The pipes feeding and leaving a water heater sit low, near a garage floor or a closet floor. That’s often the coldest air in the house during a hard freeze. Those connections rarely get insulated the way attic runs do. A split here floods a small space fast. A closet or garage utility area has nowhere for the water to spread out and slow down.

A garage wall freezes like an outside wall does

Most garages in this area sit outside the insulated part of the house. They run closer in temperature to the driveway than to the kitchen. Any supply line routed through a garage wall is exposed the same way an exterior wall line is. That includes lines feeding a sink, a water heater, or an irrigation system. Keeping the garage door closed during a hard freeze helps more than people expect.

The pipes at your house aren’t the only ones freezing

Friendswood doesn’t treat all its own water. Some comes from six deep wells around town; the rest is purchased, already treated, from the City of Houston. In a hard freeze, whichever part of that system struggles shows up here as weaker pressure at your own faucet. It could be a well pump, a Houston treatment plant, or a length of transmission line in between. A house with every pipe perfectly insulated can still lose pressure because of trouble miles away. The burst pipe cleanup page maps what that looked like the last time it happened here.

Insulation is cheaper than demolition

If a freeze warning is still days out, everything above is worth doing this weekend: foam sleeves, an open cabinet door, a disconnected hose. Once a pipe has actually split, none of that prep matters anymore. What matters then is measuring how far the water traveled, not just where the pipe broke. The emergency water removal page carries on from there if water is still spreading. The what-to-do guide steps through the rest, from the first minute to the first week.
