3 Easy Steps to Get Rid of Musty Smells in Your House 

3 Ways to Eliminate Musty Smells in Your House 
 

Mold and mildew are common, particularly in older homes. While many factors can contribute to musty smells in a house, some may indicate more significant concerns. This page explains three methods to eliminate mold growth in your home, promoting a safer and healthier living environment. 

What Causes Musty Smells in Your House? 

Numerous factors contribute to musty smells in your house, including leaky windows and plumbing pipes, poor ventilation, condensation, and inadequate airflow. Basements and crawl spaces are particularly vulnerable to mold growth, mildew, and musty odors due to their dark, often damp environments, worsened by the stack effect. The stack effect draws humid air from the foundation into the basement, releasing it through the upper floors and spreading musty smells throughout the home. Recognizing signs of mold and musty smells in your house prevents further damage and potential structural deterioration. 

3 Steps to Address Musty Smells in Your House  

When your house has musty smells, you’ll try anything to remedy the odor. Air purifiers, baking soda, and air fresheners are often the go-to choices to mask unpleasant smells, but these DIY fixes only conceal the underlying issue. Eliminating the root cause of musty smells in your house is crucial for a permanent solution. Here are five ways to get rid of musty smells in your house: 

Schedule a Professional Inspection 

The first step in identifying the cause of mold and musty smells in your house is to contact a professional. A professional inspection reveals the source of the odors and moisture, allowing for a customized repair strategy.  

Remove the Mold 

Professional mold removal is highly recommended rather than DIY mold removal for several reasons; however, it is crucial to ensure a safe and healthy home environment. DIY efforts often spread mold spores, resulting in growth in other areas. Mold can be toxic, causing health risks and worsening asthma and other conditions. Professional mold remediation, using chemical-free soda blasting techniques, is a permanent mold removal solution that ensures your home remains mold-free.   

Eliminate the Moisture 

Since damp environments foster mold and mildew, eliminating moisture is essential to addressing the underlying cause of musty smells in your house. Professionals address moisture by implementing waterproofing measures to ensure the area remains dry and resists high humidity. This approach mitigates mold, reduces energy consumption, lowers utility bills, and enhances indoor air quality.  

Basement Waterproofing   
 

Basement waterproofing protects against moisture, mold growth, and musty odors. Foundation repair experts install these waterproofing measures to prevent basement flooding and water pooling and to ensure your home remains safe and dry. 

  • Basement Sump Pumps: These pumps remove excess water from the basement to prevent flooding and water accumulation. 
  • Dehumidifiers: Dehumidifiers reduce basement humidity levels and minimize the condensation that contributes to mold and musty smells in your house. 
  • Interior Drainage Systems: Adequate drainage systems, including French drains, channel water away from the basement’s interior to prevent seepage. 
  • Vapor Barriers: These durable liners are installed to block moisture seepage through basement walls and floors.  
  • FreezeGuard™ Systems: Freeze-thaw cycles in the winter season contribute to moisture issues. Winterizing systems ensure year-round moisture control and prevent mold and musty odors. 

 
Crawl Space Encapsulation 
 

Crawl space encapsulation is a waterproofing approach that installs moisture control measures similar to basement waterproofing. This method protects the area from moisture infiltration and prevents mold growth, wood rot, and musty crawl space smells. Crawl space encapsulation also improves air quality inside the home, enhances energy efficiency, and often reduces energy bills. This approach includes: 

  • Crawl Space Vapor Barriers: These thick plastic sheets are placed on the crawl space floor to prevent ground moisture infiltration.  
  • Crawl Space Insulation: Crawl space insulation is installed on the walls or floor joists to trap heat in the winter and cool air in the summer, prevent temperature fluctuations inside the home, and enhance energy efficiency. 
  • Drainage Systems: Drainage systems utilize pipes and a sump pump to gather and expel standing water or excess moisture from the crawl space floor.  
  • Sealing Vents and Doors: This approach traps conditioned air from your house inside the crawl space, potentially improving energy efficiency and reducing energy bills. 
  • Beam Reinforcement: Crawl space beam reinforcement strengthens weakened or damaged beams, enhances structural integrity, and prevents sagging floors.  

Remove mold, eliminate moisture, and implement waterproofing methods to address and prevent the underlying cause of musty smells in your house.
