Keeping Moisture, Pest, and Structural Issues Away

When it comes to maintaining safe, sturdy, energy-efficient buildings, it’s easy to focus on the visible areas like common spaces, building siding, exterior and interior doors, windows, etc. However, one frequently overlooked area is the crawl space. Crawl spaces play an important role in maintaining the air quality, energy efficiency, and structural integrity of a building. 

The crawl space is a confined area beneath your home that typically provides access to utility systems such as plumbing, electrical wiring, and HVAC systems. If these spaces get contaminated, they can cause problems like poor air quality, subpar living conditions, mold and mildew, deteriorated insulation, pest infestation, structural damage, and low energy efficiency. Crawl space remediation removes contamination from the air, protects air quality, and maintains your building’s integrity through an in-depth cleaning of the area.

Common Crawl Space Problems


Moisture and Mold

Crawl spaces are prone to moisture accumulation, leading to mold growth, wood rot, and unpleasant odors. Excessive humidity can seep through the foundation walls or from the ground, creating an environment conducive to mold growth and compromising indoor air quality.

Pest Infestations

Dark and damp crawl spaces can attract pests like rodents, termites, and insects. These unwanted guests can cause damage to the wooden structures, insulation, electrical wiring, and more– while also presenting health risks to occupants.

Insulation Inefficiency

An unsealed or poorly insulated crawl space can result in heat loss, leading to higher energy bills. It can also make your home more susceptible to temperature fluctuations and uncomfortable indoor conditions.

Structural Weakness

Neglected crawl spaces can pose structural risks to your home as well. Moisture damage can weaken the wooden supports, leading to sagging floors, cracks in the walls, or even a compromised foundation.


Crawl Space Remediation

Your building’s air circulates through its crawl space and carries any contaminants with it. Crawl space remediation addresses these contaminants and any damage to the crawl space, which  improves air quality, enhances energy efficiency, controls pests, and maintains structural stability. 

The process starts with an inspection to identify moisture sources, mold growth, insulation deficiencies, and structural issues. The remediation process addresses moisture problems and maintains the condition of vapor barriers. If mold is present, experts employ proper techniques to remove mold growth, sanitize the area, and ensure a safe environment. Lastly, sealing air leaks and adding proper insulation enhances energy efficiency and prevents moisture intrusion.

Crawl space remediation also involves sealing off entry points, preventing pests from infiltrating your building. Remediation services can also identify and address existing infestations. By addressing moisture problems and repairing any damage, crawl space remediation ensures the long-term structural integrity of your building, protecting your investment.


Vapor Barrier Replacement

Moisture from the ground and crawl space vents can combine to create a wet crawl space barrier, leading to issues down the line with your vapor barrier. Moisture can create mold, mildew, dry rot, and allow pests to thrive. As a crawl space ground cover, a vapor barrier reduces this moisture, but any rips or tears will reduce effectiveness, and potentially leave your building at risk. 

Small rips and intrusions can sometimes be patched, but beyond small spots of exposed soil, we recommend installing a new vapor barrier throughout the crawl space. Regular maintenance and crawl space remediation help prevent large problems down the line and reduce costs over time. Properly installed vaporwave barriers should be replaced after 25 years or so.
