The Danger of Frozen Pipes and How to Prevent Them

The transition from Portland’s autumn to winter is often subtle, but savvy residents won’t let it catch them unawares. Though temperatures low enough to freeze aren’t usually an everyday occurrence in the winter, their sporadic appearance in our area can make them even more dangerous because many people haven’t prepared for them. And one of the most common issues during these cold snaps is frozen pipes.

When pipes freeze, they do more than slow down a morning routine. They create safety hazards, water damage, and costly repair needs. That is why both renters and landlords must take prevention seriously. A shared effort protects property, saves money, and keeps households comfortable during the coldest weeks of the year.

Why Frozen Pipes Are Such a Big Problem

Many people do not realize that water expands when it turns to ice. Inside a home, that expansion can create intense pressure inside a pipe. A frozen section blocks water movement while the pressure pushes against the pipe’s walls. If the pressure grows strong enough, the pipe can split or burst. Once the pipe thaws, water rushes out of the damaged section. This often happens in areas that are out of sight. A small crack behind drywall can unleash hundreds of gallons of water before anyone notices the problem.

The danger goes beyond property damage. Water that pools in walls or crawl spaces can cause mold growth. It can also weaken structural wood. In extreme cases, a burst pipe may create an electrical hazard. That is why fast action and good preparation matter for every household.

What Causes Frozen Pipes?

Oregon’s winters are far from the harshest in the country. Still, we do get our fair share of days and nights under freezing, and that can lead to frozen plumbing. Most people might think that pipes inside their home are safe from freezing, but that’s not always the case. Pipes in uninsulated or exposed areas are most vulnerable, such as inside of crawl spaces, basements, exterior walls, and areas near drafty windows.

Vacant properties are also at risk, since a home without active heating loses warmth quickly. Empty properties that sit without monitoring can develop frozen plumbing problems quietly. Renters who leave home for the holidays, for instance, might find themselves coming back to a big problem without the right preparations. This is one of the reasons both renters and landlords benefit from clear communication about winter routines.

Shared Responsibility Between Renters and Landlords

Preventing frozen pipes works best as a partnership. Landlords handle property-level systems like insulation, pipe condition, access panels, and long-term upgrades. Renters play an important role through daily habits that keep water moving and indoor spaces warm. The key lies in ensuring that both parties stay knowledgeable about their respective responsibilities. Landlords should share cold-weather instructions well before temperatures drop, and renters should ask questions when something seems unclear. When both groups understand their roles, the risk of winter damage drops significantly.

How Renters Can Help Prevent Frozen Pipes

Small choices matter when it comes to keeping a property well-maintained. For instance, people sometimes try to save money by turning off the heat at night, but during winter, this can create more problems than it solves. A steady indoor temperature protects both the household and the building.

Moving water freezes more slowly than still water; during very cold nights, leaving a slow drip at one or two faucets can help keep water moving. Cabinet doors under sinks can be propped open to allow heated air to circulate near pipes, especially near exterior walls. Renters should also stay alert to cold spots. If an area near a sink or a section of wall is noticeably colder than the rest of the house, the renter should contact the property manager quickly. Little signs like that can point to pipe sections that need insulation or minor repairs.

How Landlords Can Reduce the Risk

Landlords play a major role in long-term prevention. Regular maintenance and seasonal inspections make a big difference, including evaluating insulation around pipes, checking vent covers in crawl spaces, and confirming that vulnerable areas are sealed against drafts. Good insulation protects plumbing for many winters. It also lowers heating costs for renters and keeps rental properties warm and cozy during the cold months.

Landlords should also make sure their properties have clear instructions for emergency shutoff valves. Every renter should know where the main water shutoff is located. This simple step can prevent major damage if a pipe bursts. A little education goes a long way during winter.

What to Do if a Pipe Freezes — Or Bursts

Dealing with a burst pipe is often the nightmare scenario for renters and landlords alike, but a frozen pipe can sometimes be thawed before it bursts. If a renter suspects a frozen pipe, they should contact their property manager as soon as possible. Turning up the thermostat and using gentle warming methods on accessible pipes (such as warm towels or a hair dryer) can help as well. If the frozen pipe is behind a wall or in a place that cannot be reached safely, the renter should not try to fix it alone. A professional should handle the diagnosis and repair.

A burst pipe needs fast action. The first step: shut off the main water supply. Next, renters should contact their property manager as soon as possible. Standing water spreads quickly, so early attention prevents expensive repairs.

Landlords or property managers will need licensed plumbers to replace any sections of the home damaged by water. After the repair, the property may need drying equipment or moisture inspections. Mold prevention is essential after water damage, and early intervention keeps costs manageable and protects the health of the household.
