How to Remove Odors From a Home That Has Been Vacant Long-Term

Open all windows and exterior doors that are safe to leave open. Use fans placed in windows to push stale air out and pull fresh air in. This simple step helps clear out lingering smells from cooking, smoke, or simply months of closed-up air. Run the fans for several hours or even a full day if weather permits.

In this area, the climate swings between cold snowy winters and warm humid summers, so pick a mild day if you can. If the outdoor air is too humid, opening windows can make things worse. In that case, rely on air conditioning or a dehumidifier to keep indoor air moving and dry.

After airing out and removing sources, clean all hard surfaces. Wipe down walls, ceilings, floors, countertops, and cabinets with a mixture of water and mild dish soap or a household cleaner. Pay special attention to kitchens and bathrooms, where grime and moisture build up. Rinse with clean water and let everything dry completely.

Don't forget less obvious spots like inside closets, under sinks, and behind appliances. Use a vacuum with a HEPA filter on floors and upholstery, then mop hard floors with a cleaning solution. For stubborn odors, wipe surfaces with a solution of one part white vinegar to one part water. Let the vinegar smell fade on its own.

If smells persist after your own efforts, the cause may be deep in the structure. Odors can soak into drywall, subflooring, and insulation. In that case, professional treatment may be necessary. The pros have specialized equipment like ozone generators and thermal foggers that neutralize odors at the source.

They can also perform a moisture mapping inspection to find hidden damp spots. This helps identify whether you need structural drying or removal of affected materials. The cost depends on the size of your home, the extent of the odor, and the specific treatments used. Policies vary, and your insurer decides what is covered.
