Quick Answer
If a pipe freezes at a Richmond-area rental, shut off the water at the main valve, open the affected faucet, and gently warm the pipe with a hair dryer or warm towels while the water is off. Never use an open flame. If a pipe has already burst, leave the water off, avoid electrical hazards, and call your landlord or property manager and a plumber right away. Prevention is far cheaper than repair, and in Central Virginia most freeze damage happens during a short, sharp cold snap rather than a long winter.
Why Frozen Pipes Are a Real Risk in Central Virginia
Richmond winters are milder than many parts of the country, and that is exactly the problem. Homes here are often built with plumbing in exterior walls, crawl spaces, attics and unheated garages, with less insulation than homes in colder climates. When a night drops well below freezing, water in an exposed pipe can freeze, expand and split the pipe. The damage often shows up only when temperatures rise and the ice thaws, releasing water into walls, ceilings and floors.
The National Weather Service office serving Richmond issues freeze warnings and winter weather alerts, which are worth following from November through March.
Which Pipes Are Most Vulnerable
| Location | Why it is at risk | Fix |
|---|---|---|
| Crawl spaces | Cold air and open vents reach supply lines | Close vents in winter, add pipe insulation, seal gaps |
| Exterior walls | Little insulation between pipe and outside air | Open cabinet doors on cold nights, add insulation where accessible |
| Attics and unheated garages | No heat source | Insulate pipes, keep garage doors closed |
| Outdoor spigots and irrigation | Directly exposed | Disconnect hoses, shut off and drain, install insulated covers |
| Basements and utility rooms | Drafts from windows and vents | Seal drafts and keep the room above freezing |
Warning Signs of a Frozen Pipe
- A faucet that produces only a trickle or no water at all.
- Frost on a visible pipe.
- Strange odors from a drain or faucet, which can signal a blocked pipe.
- Unusual sounds when you turn on water.
- Water stains or dampness on walls and ceilings after a freeze.
What To Do Right Away if a Pipe Freezes
- Keep the faucet open. Running water, even a trickle, helps melt ice and relieves pressure.
- Shut off the main water valve if you suspect a crack or see water leaking.
- Warm the pipe gradually. Use a hair dryer, a heating pad or warm towels. Start near the faucet and work toward the frozen area.
- Never use an open flame, propane torch or kerosene heater. These can start a fire or damage the pipe.
- Check other faucets. If one pipe froze, others may be at risk.
- Call a plumber if you cannot find the frozen section or cannot thaw it safely.
What To Do if a Pipe Bursts
- Turn off the main water supply.
- Turn off electricity to the affected area if water is near outlets, appliances or wiring, and only if you can do so safely. If unsure, leave the home and call for help.
- Notify your landlord or property manager immediately, by phone first and then in writing.
- Take photos and video of the damage before moving anything.
- Move belongings out of the wet area if it is safe.
- Do not start repairs until the manager approves, unless you are preventing further damage.

Prevention Checklist for Owners
- Insulate exposed pipes in crawl spaces, attics, garages and exterior walls with foam sleeves or insulation rated for plumbing.
- Seal drafts around pipes where they enter the home, using caulk or expanding foam.
- Disconnect and drain hoses, and shut off outdoor spigots. Our article on fall shutdown for irrigation and outdoor spigots walks through the steps.
- Close crawl space vents in winter and repair broken ones.
- Service the heating system before the cold season.
- Show tenants where the main water shutoff is, and put a label on it.
- For vacant homes, keep heat on at a safe minimum and consider draining the system if a long vacancy is expected.

Prevention Checklist for Tenants
- Keep the thermostat at a steady setting, even when you are away. A common guideline is to avoid dropping it too low during cold weather.
- Open cabinet doors under sinks on exterior walls during freezing nights.
- Let a faucet drip slightly during extreme cold if your property manager recommends it.
- Disconnect garden hoses before the first freeze.
- Report drafts, missing insulation and slow leaks right away.
- Know where the main water shutoff is.
Who Pays When Pipes Freeze or Burst?
Responsibility depends on the cause and on the lease. Landlords generally maintain the plumbing and the structure, while tenants must use the property reasonably and report problems promptly. If a tenant turned off the heat, left a window open or ignored obvious warnings, the landlord may seek reimbursement. If the cause was poor insulation or an old pipe, the owner typically bears the repair cost. Tenant belongings are usually covered by renters insurance, not by the landlord’s policy, so renters should consider a policy. The Virginia Residential Landlord and Tenant Act describes the duties of each side.
Handling Water Damage and Mold After a Burst
Water can spread quickly into insulation, drywall and flooring. Dry out the area as fast as possible with fans and dehumidifiers, and remove soaked materials that cannot be dried. Mold can begin to grow within a couple of days in damp conditions, so speed matters. For large losses, a restoration company can measure moisture and document the work for insurance. Owners should notify their insurer promptly, keep invoices and photos, and communicate with tenants about timelines and any temporary relocation.
Tenant rights if the home becomes unlivable
A burst pipe that makes part or all of a home unlivable can raise questions about rent abatement or ending the lease. These are fact-specific, and the law has procedures. Read about habitability, and speak with an attorney or legal aid if the situation drags on.
Smart Devices That Help
Inexpensive water sensors can alert you to leaks, and some can notify you of low temperatures. Smart thermostats can warn you if the heat fails. Smart shutoff valves can stop water automatically in some situations. These devices are optional, but for a remote owner or a vacant home they can reduce risk. Make sure tenants know about any connected devices installed in the home.
A Cold Snap Action Plan
When a hard freeze is forecast, follow a short plan. Check the forecast a few days ahead, and send a message to tenants with simple steps. Confirm that heat is working at vacant properties. Inspect vulnerable areas, such as crawl space vents and garages. Keep your plumber’s contact information handy, and ask whether they provide emergency service. After the cold passes, inspect for leaks and repair any damage while it is small.
Insulation Materials: What Works Best
Foam pipe sleeves are inexpensive, easy to cut and fit most supply lines, making them the first choice for many owners. Fiberglass wrap works in some areas but can trap moisture if it gets wet. For pipes in very exposed spots, electric heat tape or heat cable with thermostatic control offers extra protection, but it must be installed according to the manufacturer’s instructions and replaced if damaged. Never layer heating products improperly, since misuse can create a fire hazard.
When you insulate, work on the most exposed lines first, such as those in crawl spaces and along exterior walls. Seal gaps where pipes pass through the wall or floor, since even a small draft can freeze a line. Keep a record of what you installed and when, so the next inspection is quick.
Training Residents Before the First Freeze
A short message in early November pays off all winter. Tell residents where the main water shutoff is, explain how to disconnect hoses, and share the property manager’s after-hours number. Encourage them to report drafts or slow leaks promptly. Residents who know what to do act faster, and fast action is what keeps a frozen pipe from becoming a flood.
