The short answer
First Steps After Returning
When you return to a house that has sat empty for months, begin with a slow walk-through. Look for visible signs of water damage, such as stains on ceilings or walls, warped floors, or a musty smell. Check under sinks, around toilets, and near the water heater for leaks or standing water.
Next, turn on the main water supply and watch for sudden pressure drops or leaks. Open a few faucets to flush the pipes, and listen for unusual sounds. If you notice damp spots or pooling, shut off the water and address those areas before moving on. Acting quickly helps prevent further damage.
- Check ceilings and walls for stains or peeling paint

Dealing with Water Damage
If you find water damage, the first priority is to stop the source. That could mean shutting off the water supply, fixing a leaky pipe, or patching a roof. Once the source is controlled, remove any standing water using a wet vacuum or mop. Dry out the area with fans and dehumidifiers to prevent mold growth.
For serious water damage, especially if it affected drywall, flooring, or structural wood, you need professional help. Local water damage pros have the equipment to extract water and dry materials thoroughly. They can also identify hidden moisture that you might miss. Delaying can lead to rot and mold, so act quickly.
Checking for Mold and Mildew
Mold thrives in damp, dark places, so a long vacancy often leads to mold problems. Look for black or green spots on walls, ceilings, and baseboards. Pay special attention to bathrooms, basements, and areas near windows. If you see mold, do not touch it without protection; wear gloves and a mask.
Small patches of mold can be cleaned with a mild detergent and water. Larger infestations or mold inside walls require a mold professional. They can remove the mold safely and address the moisture source. If you have breathing issues or allergies, see a doctor if you feel unwell after exposure.
Inspecting Systems and Appliances
A vacant house can have issues with its plumbing, electrical, and HVAC systems. Check the water heater for leaks or corrosion, and inspect the furnace and air conditioner for dust or damage. Turn on appliances like the dishwasher and washing machine to see if they work properly. Look for signs of rodent or insect damage to wires and insulation.
If you suspect a hidden leak, consider professional leak detection. Pros use specialized tools to find leaks behind walls or under floors without tearing everything apart. They can also check moisture levels in building materials. Catching problems early saves you from costly repairs later.
Preventing Future Vacancy Issues
Once your house is back in order, take steps to avoid problems if you leave it vacant again. Keep the heat on at a low setting during winter to prevent pipes from freezing. Have someone check on the house regularly and run water occasionally to keep traps filled. Shut off the main water supply if you can, and drain the pipes.
If you live in Redmond, keep your shutoff valve location written down. Also, consider installing a smart water leak detector that alerts you to leaks even when you are away. These simple measures can save you from major water damage. Remember, a little planning goes a long way.

How long can a house sit vacant before problems start?
Issues can appear within a few weeks, especially if there are hidden leaks or high humidity. Mold can start growing in 24 to 48 hours after moisture exposure. The longer a house sits empty, the higher the risk of damage. Check on it regularly or ask someone to do so.
What should I do if I find standing water in my vacant house?
Turn off the water supply and electricity in the affected area if safe. Remove the water with a wet vacuum or mop. Dry the area with fans and dehumidifiers. For large amounts of water or if it has soaked into walls and floors, contact the pros to extract and dry properly.
Can I clean mold myself or should I hire a professional?
Small patches of mold on non-porous surfaces can be cleaned with detergent and water. However, if mold covers a large area, is in the HVAC system, or is inside walls, you need a mold professional. They have the equipment to remove mold safely and fix the moisture problem. Protect yourself with gloves and a mask.
