Your Vacation Rental Smells Musty After Winter — Here’s How to Fix It Before Spring Guests Arrive

Spring is the most anticipated season in the short-term rental industry. Guests are booking beach houses, mountain cabins, and lakeside retreats at record rates — and the last thing you want is a negative review mentioning a stale, musty smell the moment they walk through the door.

The Symptom: That Unmistakable Post-Winter Mustiness

If your vacation rental sat closed or underused during the winter months, you have almost certainly encountered this problem. Guests open the front door and are immediately greeted by a damp, stale odor that no amount of air freshener can fully mask. They notice it in the bedrooms, in the bathrooms, and especially in closets and under furniture. Within minutes, they are reaching for their phones to leave a one-star review — before they have even unpacked.

This musty smell is not simply a matter of the property being closed up. It is the result of several compounding issues that develop over the winter season: moisture trapped in fabrics and carpets, mold and mildew growth in bathrooms and kitchens, dust accumulation on surfaces and in HVAC vents, and the slow breakdown of organic matter in drains and garbage disposals. Standard cleaning does not address these root causes.

Why This Happens to Short-Term Rentals Specifically

Unlike a primary residence where daily activity keeps air circulating and surfaces clean, a vacation rental that sits vacant for weeks or months becomes a sealed environment. Humidity levels rise and fall with the weather, creating the perfect conditions for mold spores to settle and multiply. Soft furnishings — mattresses, sofas, curtains, and rugs — absorb ambient moisture and hold it long after the air has dried out. HVAC systems that have not been run regularly accumulate dust and debris that gets blown through the property the moment the heat or air conditioning is turned back on.

The Solution: A Professional Spring Deep Clean

A professional spring deep clean from Vacation Property Maids goes far beyond a standard turnover clean. Our certified cleaning teams are specifically trained to address the unique challenges of short-term rental properties coming out of the off-season. Here is what a comprehensive spring deep clean includes:

• Deep mattress and upholstery treatment — We use professional-grade deodorizers and sanitizers to eliminate odor-causing bacteria trapped in soft furnishings.
• Mold and mildew treatment — Every bathroom, kitchen, and laundry area is treated with EPA-approved mold inhibitors, with special attention to grout lines, caulking, and under-sink areas.
• HVAC vent and filter cleaning — We clean all accessible vents and replace filters to ensure fresh, clean air circulation from the first moment guests arrive.
• Full interior window cleaning — Winter grime on windows is removed, allowing natural light to brighten the space and help eliminate residual dampness.
• Drain and garbage disposal treatment — Organic buildup in drains is cleared and treated to eliminate one of the most common hidden sources of bad odors.
• Baseboards, crown molding, and ceiling fans — Dust accumulation on these frequently overlooked surfaces is thoroughly removed.

The Business Case: 5-Star Reviews Start at the Front Door

Research consistently shows that cleanliness is the single most important factor in Airbnb and VRBO guest reviews. A property that smells fresh and clean the moment guests arrive sets a positive tone for the entire stay, dramatically increasing the likelihood of a five-star rating. Conversely, a musty smell is one of the most commonly cited complaints in negative reviews and can be nearly impossible to recover from once it appears in your listing’s review history.

Investing in a professional spring deep clean before your first spring guests arrive is not an expense — it is a revenue protection strategy. The cost of a single negative review, in terms of lost bookings and reduced nightly rates, far exceeds the cost of a thorough professional cleaning.
