There’s something nostalgic about old homes — their architecture, character, and history often make them feel special. However, one thing that’s not so charming is the unmistakable “old house smell.” That musty, stale odor can make your home feel uninviting, no matter how clean it looks. If you’ve just moved into an older property or have lived in one for years, understanding the cause of these smells and how to eliminate them is key to restoring freshness.
Here’s a complete guide on how to get rid of old house smell — and when it’s time to call in professional odor removal experts.
How to Get Rid of Old House Smell in Tacoma
1. Identify the Source of the Odor
Before you can effectively get rid of any unpleasant smell, you need to find out where it’s coming from. In older homes, odors tend to linger because materials like wood, carpet, and drywall absorb smells over time. Common culprits include:
- Mold and mildew: Moisture buildup in basements, crawl spaces, or behind walls can lead to hidden mold growth.
- Old carpets and upholstery: Fabric materials trap years of dust, pet dander, smoke, and musty odors.
- Poor ventilation: Older homes may have limited airflow, allowing stale air to accumulate.
- Plumbing issues: Sewer gas or stagnant water can produce foul smells that spread through the house.
- Previous occupants: Cigarette smoke, pets, or cooking odors can persist long after the source is gone.
Once you pinpoint the cause, you can focus on removing it rather than just masking the smell.
2. Deep Clean Every Surface
A thorough cleaning is the first and most important step. Start from the top down:
- Walls and ceilings: Use a mixture of warm water and mild detergent to wipe down surfaces that may have absorbed odors. Nicotine stains and grease are common in older homes and need special attention.
- Floors: Steam clean carpets and rugs, or consider replacing them if they’re beyond saving. For hardwood or tile floors, mop with a deodorizing solution like white vinegar and water.
- Furniture and drapes: Wash or dry-clean curtains, and vacuum upholstery using a HEPA filter to trap odor-causing particles.
- Hidden spaces: Don’t forget closets, basements, attics, and under furniture — these areas often harbor lingering smells.
3. Improve Air Circulation
Stale air is one of the main contributors to an old house smell. Make sure to ventilate your home properly:
- Open windows and doors whenever possible to let fresh air in.
- Use exhaust fans in bathrooms, kitchens, and laundry areas.
- Replace HVAC filters regularly — dirty filters can recirculate odors throughout the house.
- Consider installing an air purifier with an activated carbon filter to help remove airborne odor particles.
Improved air circulation not only helps eliminate smells but also prevents mold and mildew from returning.
4. Use Natural Deodorizers
Instead of masking smells with air fresheners, use natural odor absorbers:
- Baking soda: Place open boxes around the house — especially in basements, closets, and near garbage bins — to neutralize odors.
- White vinegar: Set bowls of vinegar in different rooms to absorb stubborn smells. It dissipates quickly but takes the odor with it.
- Charcoal bags: Activated charcoal is excellent for absorbing moisture and odors naturally.
- Essential oils: Add a few drops of lemon, lavender, or eucalyptus oil to a diffuser for a clean, pleasant scent.
These methods are safe, affordable, and environmentally friendly ways to maintain a fresher indoor environment.
5. Address Moisture Problems
Old homes are notorious for humidity and water intrusion issues, both of which can cause persistent odors. Inspect your property for leaks, foundation cracks, or condensation problems. Use a dehumidifier in damp areas like basements or crawl spaces to keep humidity levels below 50%.
If you suspect mold is growing behind walls or under floors, don’t ignore it. Mold not only causes musty odors but can also affect your health and damage your home’s structure.
6. When to Call a Professional Odor Removal Service
If you’ve tried everything and the old house smell won’t go away, it’s likely embedded deep within the structure — in HVAC ducts, insulation, or wall cavities. That’s when professional help makes all the difference.
