Homeowners in Lambertville, MI, know that moisture and humidity can be ongoing challenges, especially in older homes with vented crawl spaces. High humidity levels not only affect air quality but can also lead to insulation deterioration, mold growth, and higher energy bills. That’s exactly what one Lambertville homeowner was facing until they called Toledo Basement Repair to transform their damp crawl space into a clean, energy-efficient area.
Identifying the Problem
During the initial inspection, our team found several common issues contributing to poor indoor air quality and moisture concerns. The existing vapor barrier in the crawl space was deteriorating, allowing ground moisture to rise and circulate throughout the home. Additionally, fiberglass insulation had started to sag and collect condensation, making it less effective and increasing the potential for mold growth. The homeowner’s goal was clear: reduce humidity, improve air quality, and create a long-term solution for energy efficiency.
Crafting the Right Solution
After a thorough assessment, we designed a comprehensive crawl space waterproofing and encapsulation plan tailored to the homeowner’s needs.
1. Insulation Removal
We began by removing all old fiberglass insulation from the crawl space. Fiberglass tends to absorb moisture and lose its insulating properties over time, making it a poor choice for this type of environment. Clearing it out allowed us to start fresh with a clean surface and prepare for advanced insulation installation.
2. Closed-Cell Spray Foam Insulation
Next, our team applied closed-cell spray foam insulation, a cutting-edge product that provides nearly double the insulating value of traditional materials. This insulation completely seals air leaks and gaps, offering benefits such as:
Superior energy efficiency: Keeps the home warmer in winter and cooler in summer.
Moisture and mold resistance: Impervious to water, preventing condensation and microbial growth.
Durability: Unlike fiberglass, spray foam doesn’t sag or degrade over time.
We also installed unfaced R-19 insulation along the rim joists to ensure optimal thermal protection and further minimize air infiltration.
3. CrawlShield™ Encapsulation System
To fully control moisture and protect the crawl space, we installed the CrawlShield™ Encapsulation System, the industry’s top solution for crawl space protection. This system creates a durable vapor barrier that covers both the foundation walls and floor, preventing ground moisture and soil gases from entering the living space.
Underneath the encapsulation, we added a DimpleShield™ drainage layer, which provides puncture resistance and an added layer of groundwater protection. The CrawlShield™ material itself is a 16-mil woven polyethylene—fire-retardant, puncture-resistant, and Class A fire rated. All seams were carefully sealed using FinishTape™ and FinishSeal™ to ensure a continuous and airtight barrier.
As a finishing touch, we sealed all vents with polystyrene inserts and applied a single coat of Concrobium Mold Control, a powerful antimicrobial treatment designed to eliminate and prevent future mold growth.
Delivering Lasting Results
The transformation was dramatic. What once was a damp, neglected crawl space became a bright, clean, and energy-efficient environment. The homeowner immediately noticed a reduction in musty odors and improved indoor air quality throughout the home. With the CrawlShield™ system in place, moisture migration was stopped, protecting the home’s foundation from long-term damage.
In addition, the closed-cell spray foam insulation now helps the home maintain consistent temperatures year-round while reducing heating and cooling costs. The encapsulated crawl space is not only functional but also usable for storage—clean, dry, and safe.
