"I don't leave a lot of reviews, but the Groundwork crew and the encapsulation work are exceptional, so here goes. We have a pretty large crawl space under our 30-year old house. The team (Wyatt, Zane L. And Volodymyr M.) worked really diligently to get the 5 day job done. They managed a huge amount of cleared-out debris, and thoroughly cleaned up all of the construction material after they installed. No sign of any dust, garbage or debris after they finished the job. Not even a staple. The encapsulation looks fantastic and it's so nice to have the area dry, insulated and clean. Oh, and they were able to install the dehumidifier in a place that is easily accessible when we need to clean the filter. Just really glad we decided to do this. Wyatt S. Went out of his way to keep us well informed of when the team coming each day, when they took breaks and when they were going home at night. He shared progress photos each day and addressed all of my concerns. I've worked with many contractors and these guys are at the top of their game."

Standing water in your crawl space won’t disappear on its own. Keep the drainage clear, ensure the vents are working properly, and run a dehumidifier to control moisture levels. If dampness lingers, mold, wood rot, and foundation cracks can follow. Act quickly and call a pro to protect your home’s structure and indoor air quality.
Disinfecting a crawl space requires a methodical approach. First, clear all debris and remove old liners and insulation to eliminate contaminants. Then, apply a strong bleach solution or borate spray to eradicate mold spores and mildew. Ensuring complete surface coverage and allowing ample drying time establishes a sanitary environment and prevents future infestations.
A crawl space serves vital functions by providing access to essential systems, including electrical wiring, plumbing, and HVAC ducts. It also offers a buffer zone that aids in moisture control and protects underlying structural components.
Yes, crawl space encapsulation is a worthwhile investment in protecting your home. Crawl space encapsulation locks out moisture, controls humidity, and blocks pests and harmful pollutants like radon gas. Those benefits boost indoor air quality and protect beams, joists, and insulation, giving your home long‑term structural stability and safeguarding your family’s health.
Prevention is the best way to keep water out of your crawl space. A dehumidifier and sump pump can help control moisture levels, but grading the landscape to redirect water away from the foundation is most important. Additionally, seal foundation cracks and install reliable drainage systems such as a French drain to maintain a consistently dry environment.
Yes, repairing your crawl space foundation is critical, regardless of how minor the issue may seem. Foundation problems arise from enduring moisture, water intrusion, and unstable soil, which can lead to significant structural damage if left unaddressed. Hiring a licensed structural engineer or foundation repair professional guarantees your home’s long-term stability and safety while preventing escalating repair costs.
