"Gerad Walker came out to my house to check on my crawl space. He found the dehumidifier that I thought had quit working had been set to high. He adjusted the settings and said the unit was working like a champ. In this day and time it is rare to have someone not give you a long story of what they found and how much it was going to take to correct. Having someone be 100% honest and fix your situation without charging you a dime is very rare. I'm a fan of this company and will use them again, for sure."

Master Services is your local, certified basement and foundation repair company. We specialize in professional services that improve the health and functionality of your below-grade space, including basement waterproofing, crawlspace repair, foundation repair, and concrete leveling.

"A little late on my review. First issue is a salesman that has no idea weather the foam injection is an open cell or closed cell. After 2 years of a portion of the foam that was shot under the exterior undermined concrete was destroyed. Oil base foam was used for no UV breakdown like the technician said I needed to do when I asked. Even with no sunlight the foam absorbed moisture, Now after thousands of dollars spent on leveling with open cell foam it was only a treatment of the symptom and not a cure. So far the undeveloped concrete is now heading back to where it was. Not to mention the stabilize part of the bill of goods does not happen when there are still areas the vibration from an air compressor running. The actual cause of the unlevel concrete is no compaction of the ground and the lazy man saw cut expansion joint just like I thought! But do not tell a salesman any common sense reason."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Knoxville, TN

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.
