How Do You Winterize a Houston High-Rise Condo Before a Freeze?

Before a freeze, the building and the owner each have a job. In a Houston high-rise, the association and its management company protect the building’s systems: exterior pipes, fire sprinkler lines in garages and stairwells, and the equipment on the roof. You protect your unit. That means keeping the heat on, knowing where your water shutoff valve is, and reading two documents before the cold arrives: your condo declaration and your HO-6 insurance policy.

Most Houston condo owners do not think about any of this until February. That is about four months too late.

Why High-Rises Get Hit Differently

A single-family home with a frozen pipe floods one house. A high-rise with a frozen pipe on the 14th floor can send water through every unit below it. That is the whole reason freeze prep in a tower is a shared job. During Winter Storm Uri in February 2021, burst pipes and sprinkler lines damaged buildings all over Houston, and many owners learned for the first time what their declaration said about who pays.

Houston towers are built for heat, not cold. Pipes in parking garages, exterior walls, balconies and unheated mechanical rooms are the weak spots. A well-run building insulates exposed pipes in exterior areas and has a freeze plan for its sprinkler system. Texas management companies such as FirstService Residential publish their high-rise winter prep steps every year, and it is fair to ask your manager what your building’s plan looks like.

Your Unit Checklist

Here is what is on the owner’s side of the line in most buildings:

1. Leave the heat on, even if you will be gone. A cold unit is how pipes in an outside wall freeze.
2. Find your unit’s water shutoff valve now, while nothing is leaking. In some buildings it is behind an access panel. In others it is in a hallway closet.
3. Open the cabinets under sinks on exterior walls so warm air reaches the pipes.
4. Know where your water heater and any in-unit valves are, and make sure nothing is stacked against them.
5. Tell management if you will be away during a freeze, and leave a way to reach you.
6. Follow the building’s instructions. If management asks owners to drip faucets or to leave water on, do that. A building’s plan beats generic advice.

The Texas Department of Insurance’s winter tips suggest turning off the water at the shutoff valve and leaving the heat on if you leave home before a possible freeze. In a tower, check with management before you do that, since some units share valves.

The Two Documents That Decide Who Pays

This is where people get uncomfortable. The answer to “who pays for the water damage” is not in the weather report. It is in paperwork you probably signed and never read.

Your condo declaration. Most Texas condos created after 1994 fall under the Texas Uniform Condominium Act in Chapter 82 of the Property Code, but the declaration is what spells out the details for your building: which pipes belong to the association, which belong to you, and who carries the master policy deductible when a leak starts in your unit. In many buildings, that deductible can land on the owner where the leak began.

Your HO-6 policy. This covers the inside of your unit, your belongings, and often a slice of a special assessment through loss assessment coverage. The Texas Department of Insurance warns that a policy might not pay for frozen pipe damage if you did not take steps to protect your pipes, like keeping the heat on. Read the freeze and vacancy sections, and ask your agent whether your loss assessment limit covers your building’s master deductible.

If you are shopping for a high-rise, ask for the declaration and the master policy during your option period. Our piece on luxury condo HOA reserves in Houston covers the reserve study questions that go with it.

What We Look For

Peter spent years in construction before he started selling homes, and that background is useful in a tower. The questions he asks on a high-rise showing are simple: where does the plumbing run, do any pipes sit in exterior walls or near balconies, and what did the building change after 2021? A building that replaced or insulated its exposed lines tells you something about how it is managed.

Frequently Asked Questions

What should a Houston condo owner do before a hard freeze?

Keep the heat on in your unit, find your unit's water shutoff valve, open the cabinets under sinks on outside walls, and follow any freeze instructions from building management. If you will be away, tell management and confirm the heat stays on.

Who pays if a frozen pipe floods my Houston condo?

Your condo declaration decides that. In many buildings, the declaration makes the association responsible for common pipes and the owner responsible for pipes and finishes inside the unit, with the master policy deductible often landing on the owner whose unit the leak started in.

Does my HO-6 policy cover frozen pipe damage?

Usually, if the damage is sudden and you took reasonable steps to prevent it. The Texas Department of Insurance warns that policies might not pay for frozen pipe damage if you did not take steps such as keeping the heat on, so read your policy's freeze and vacancy terms.

Should I turn off the water in my condo during a freeze?

If you are leaving during a possible freeze, the Texas Department of Insurance suggests turning off the water at the shutoff valve and leaving the heat on. In a high-rise, ask management first, because some units share valves or have rules about shutting water off.
