New business owner. Started officially in April of 2020. We offer traditional encapsulation options for those that WANT that type of system. But our primary focus is directed toward those who live in flood zones. The product we use is specifically designed for crawlspace framing and is a FEMA flood grade rated product. Our innovative option is backed with a Lifetime multiple event flood warranty and may also qualify homeowners for flood credits through their homeowners insurance.

"I hired Matt to replace door frames on my home which should have only taken a few days and into week three of him showing up late or not showing up at all and consistently asking for money to go buy supplies and then coming back with a receipt where most of the supplies were tools for him to do the job I finally called someone to come out and inspect the work that he had done and the guy said it was the shottiest work that he had ever seen. He ruined a brand new PVC door frame that I purchased and now I have to purchase a new one because it’s not fixable. I gave Matt money to go buy trim and door hinges, and he never returned. he also took the PVC that I purchased and ran away with it. I would highly recommend that you stay away from this guy. He also installed flooring in my laundry room and cracked the washer drain and didn’t replace it. He took $700 from my neighbor and when she saw the work that he did on my doors, she told him that she wanted to cancel the contract he hadn’t even started yet, and it’s been a week and he has not replied to any messages and won’t answer his phone. I really hate giving bad reviews, but if anyone deserves it, he does. It’s now going to cost me $650 to fix his mistakes."

Mold Testing and Remediation questions, answered by experts

Combining mold testing and remediation with upgrades like crawl space encapsulation, basement waterproofing, or HVAC improvements in Charleston can streamline your project and reduce disruption. Addressing insulation, ventilation, or replacing water-damaged materials during remediation helps prevent future mold issues. This approach is especially effective in Charleston’s humid climate, maximizing the impact of your investment and supporting long-term indoor air quality.

Helpful?

In Charleston, hidden costs during mold testing and remediation can include repairing subfloors, drywall, or insulation damaged by moisture. Historic homes may require specialized materials or extra care for lead paint or asbestos. Plumbing or foundation repairs, emergency water extraction, and temporary accommodations might be needed. Post-remediation air quality testing and installing moisture monitoring equipment are sometimes necessary, so it’s smart to budget for these potential surprises.

Helpful?

In Charleston, ongoing maintenance after mold testing and remediation involves regularly using dehumidifiers to control humidity, especially during humid summers. Inspect basements, crawl spaces, and plumbing monthly for leaks or moisture. Change HVAC filters every three months, clean ducts annually, and keep gutters clear to direct water away from your foundation. Annual indoor air quality testing is recommended, especially in historic homes or after heavy storms.

Helpful?

Your Charleston home may need mold testing and remediation if you notice musty odors, visible mold, water stains, or peeling paint, particularly in crawl spaces or basements. Homes with past flooding, poor drainage, or older construction are at higher risk. If you or your family experience increased allergies or respiratory issues at home, it’s wise to seek a professional assessment, especially in flood-prone neighborhoods.

Helpful?

In Charleston, you’ll find certified mold inspectors for testing, mold remediation specialists for removal, and indoor air quality experts for ongoing monitoring. Water damage restoration contractors often handle both moisture and mold issues, offering emergency response. For historic homes, restoration specialists understand preservation needs, while crawl space contractors focus on moisture control unique to local architecture. Always choose professionals familiar with Charleston’s climate and building styles.
