Winterizing Your Ocean City MD Condo or House

Turning off the water doesn’t mean you can turn off the heat. And leaving the heat on doesn’t mean you can forget about the property until spring.

I’ve seen both situations end badly. During the winter of 2025 to 2026, an owner lost the use of their property after the heat was turned off and pipes burst. In another case, the owner left the heat on, but the equipment stopped working. The damage reached that condo and three units below it.

These are the things worth understanding before you lock the door for the season. A few decisions now can make a substantial difference in what you come back to.

Two winter losses that explain why this is important

The first property, in my example above, was closed up by someone who hadn’t handled that responsibility in previous years. They turned off the heat, believing that was the right thing to do for a place that nobody would be using.

During the winter of 2025 to 2026, pipes froze and water damaged the property from top to bottom. The owner told me the insurance company denied the claim because the heat had been turned off. According to the owner, the resulting mitigation, repair and replacement costs ultimately forced them to sell.

That's just one example of why you need to understand your responsibilities before leaving your beach home this fall.

In the second case that I outlined above, the owners left the heat on. The issue arose because the heat pump failed during cold weather, and the owner didn’t have remote temperature monitoring to alert them that the condo was getting colder. A pipe eventually burst, damaging their unit and the three units below them.

If that property owner had installed a Wi-Fi thermostat with temperature alerts, the damage might not have ever happened.

Start with your building and your equipment

All condos are not the same. They aren’t built the same, they don’t have the same systems, and their associations don’t necessarily have the same 'winter' rules.

Read your association’s winter instructions and governing documents. Ask what owners must do, what the association handles and who to contact when something goes wrong. Then check your insurance requirements and the instructions for your particular equipment.

This is specifically important when shutting off your water. You need to identify the correct domestic-water 'shut-off' valve and you need to understand what it supplies. For example, you don't ever want to shut down a shared building supply, a fire-sprinkler supply or water needed by a heating system.

If you’re unsure, contact the Association or a licensed plumber, and have them explain the procedure. "Guessing" is never the right decision.

Keep the heat on and know that it is working

“A lot of people think they can just turn the heat off. That's not true.”

Grant Fritschle

Water remaining in the system can still freeze, and your unit may also be affected by plumbing serving other parts of the building.

Follow the temperature requirements for your association, insurance policy and property. Don’t assume that the lowest setting on the thermostat is an appropriate winter setting, or that the room where the thermostat sits represents the temperature around every pipe.

I recommend having the heating system checked before the cold weather arrives. Then make sure someone can tell whether it’s still operating while you’re away.

A Wi-Fi thermostat can help you see the actual temperature rather than simply remembering what you set it to when you left. Enable low-temperature alerts, test the notifications and make sure they go to someone who will act on them.

The heating bill is part of protecting the property. Saving a little there can become very expensive elsewhere.

Follow the correct water and water heater procedure

For many owners, "closing up" includes shutting off the unit’s domestic water supply. Whether and how you should do that depends on the plumbing, equipment and building requirements.

Water-heater instructions also vary. An electric storage tank, a gas water heater and a tankless system don’t all follow the same procedure. Follow the manufacturer’s instructions or have a qualified professional handle it.

One detail deserves particular attention when you return: an electric-tank water heater must be full before you turn the breaker back on. Don’t switch the breaker on first.

Also ask about appliances connected to the water supply, including the refrigerator’s ice maker. A properly planned shutdown accounts for those connections instead of stopping at the main valve.

Understand what your association actually handles

This is worth understanding before you buy, too. When comparing a condo, townhouse or house, look at the ownership 'structure' and governing documents, not just the building’s appearance.

Some fee-simple townhouses have associations; others don’t. Where there’s no association or shared arrangement handling maintenance, the owner’s responsibilities can be much like those of a detached house.

Our guides to buying an Ocean City condo and what condo fees cover explain why those details deserve attention.

Arrange a person who can respond

That service may not be included, and emergency responsibilities depend on the management agreement and building procedures.

Ask directly: Who checks on the inside of my beach property? How often? What do they check? Who contacts you if something is wrong? Who can I contact if something goes wrong?

A property-check service, a trusted neighbor or another reliable local contact can be part of your plan. Make sure you agree on access, contact information and what should trigger a call to a professional.

Smart devices add another layer of protection. A Wi-Fi thermostat with low-temperature alerts can warn of falling temperatures; a flow monitor may identify unusual water use in the off-season; and some systems can automatically even close an approved water valve. Their capabilities differ, and connected alerts depend on the necessary power and communications working.

After a major storm or extended power outage, have someone inspect the property for damage and confirm proper system operation. Don’t assume everything restarted correctly simply because power returned or the thermostat came back online.

Secure the things wind can move

Some of the preventable damage I see most often involves patio furniture and sliders.

Furniture left on a balcony can be picked up by wind and driven into the glass. Owners sometimes expect to return before the next storm, or assume a heavy piece won’t move. Bring loose furniture and other outdoor items into an appropriate indoor storage area before leaving for an extended absence.

Then physically check every door, window and slider. Something can look closed without being fully seated or locked. A small opening can admit cold air and water for weeks before anyone notices.

Close storm shutters where appropriate and follow the building’s instructions. For a house or townhouse, also address exterior items such as hoses, outdoor plumbing, gutters, sheds and dock equipment according to the property’s needs.

Remember that your neighbor can affect your property

“Frozen pipes is a big deal, and it doesn't just happen because your heat's off. It can happen because your neighbor's heat's off.”

Grant Fritschle

That’s an important part of condo ownership. You can follow the instructions inside your own unit and still experience damage originating elsewhere in the building.

It’s one reason I pay attention to how an association communicates and enforces winter requirements. Clear rules help, but owners also have to follow them, and the building needs a workable response when a problem is reported.

When choosing a condo building, ask about maintenance and seasonal procedures along with the amenities. Those answers tell you something about the ownership experience.

Give coastal heating equipment the attention it needs

Salt exposure is part of owning at the beach, and outdoor HVAC equipment needs maintenance suited to that environment.

I’ve owned in a building where the heat pumps sit beneath the structure in the parking area. They were sheltered from rain, which meant salt residue wasn’t being washed away naturally.

Ask your HVAC professional about the appropriate cleaning method and schedule for your equipment, including whether manufacturer-approved freshwater rinsing is recommended. Don’t improvise with a pressure washer or cleaning chemicals.

The goal is to keep the equipment operating reliably and address corrosion before it becomes a bigger problem. That’s particularly important when the system will be protecting an unoccupied property through the winter.

Decide whether the property is closed or available for use

Before shutting anything down, decide how you intend to use the property over the winter.

If you’re closing it for the season, follow a consistent closing plan. If you’ll visit or accept winter rentals, establish who prepares it for arrival and who checks it after departure. An occasional weekend shouldn’t leave everyone assuming someone else reset the heat or secured the slider.

For rental properties, discuss those responsibilities with your rental manager. Our guide to Ocean City vacation-rental earnings can help frame the larger decision about seasonal use.

And don’t overlook using the property yourself. Many owners discover that a few days away in the off-season become part of why they enjoy owning here. Our guide to Ocean City in winter explores that side of the decision.

Ask the insurance questions before there is a claim

For a condo, understand how your unit-owner policy, often called an HO-6 policy, works with the association’s master policy. Neither should be treated as a substitute for understanding the other.

Ask your agent what your policy requires during extended absences, including any conditions concerning heat, water shutdown or property inspections. Explain how you actually use the property, including seasonal occupancy and rentals.

Our guide to condo master insurance and HO-6 coverage provides a starting point. Water damage also isn’t one single insurance category: a burst pipe, wind-driven rain and flooding can involve different coverage questions. See our Ocean City flood-insurance guide for that distinction.

Before you lock the door

Use this as a final review alongside your property-specific instructions:

• Confirm the association’s winter requirements and your insurance conditions.
• Check that the heating system operates and leave it at the appropriate setting.
• Follow the approved domestic-water and water-heater procedures.
• Bring loose outdoor furniture and other items into suitable storage.
• Physically check doors, windows, sliders and applicable storm shutters.
• Test monitoring devices and alert notifications.
• Confirm who can enter, inspect and respond while you’re away.
• Arrange an inspection after a major storm or extended power outage.
• Record the closing date, settings and checks for your own reference.

Frequently asked questions

Can I turn off the heat if I shut off the water?

Don’t assume that makes it safe. Closing a supply valve doesn’t drain the plumbing. Follow your building’s requirements and the professional guidance for your property, and keep the heat operating as required.

Will the association manager check inside my condo?

Only if that service is part of the arrangement. Confirm the scope and frequency rather than assuming routine inspections are included.

Is a smart thermostat enough?

It’s useful, but it doesn’t replace a response plan. Someone needs to receive the alert and be able to arrange access and assistance. Physical inspections also identify problems a thermostat won’t detect.

Will insurance cover a frozen pipe?

Coverage depends on the policy and circumstances. Ask your agent about your obligations before leaving, especially requirements related to heat, extended absences and inspections.

What winter damage could have been prevented?

Some of the preventable damage I see most often involves patio furniture and sliders. Furniture left on a balcony can be picked up by wind and driven into the glass, and something can look closed without being fully seated or locked.

What should I do with an electric water heater when I come back?

An electric-tank water heater must be full before you turn the breaker back on. Don’t switch the breaker on first.
