Crawl Space Drainage Systems
in North & South Carolina

Water is a stubborn houseguest. Once it gets into your crawl space, it settles in, puts its feet up, and refuses to leave. And in the Carolinas, rain and damp soil makes it easy for water to sneak in and stay awhile. Without proper drainage, that lingering moisture raises humidity, invites mold, and weakens your home’s structure. Moisture Loc’s drainage systems move water out and keep it out.

  • Reduces standing water and humidity
  • Prevents mold growth and wood rot
  • Improves air quality upstairs

Give water an easy way out.

Why Crawl Space
Drainage Matters

Around here, it’s really hard to keep water outside. Any crack or crevice can be an entryway into your home, and with the amount of rain and humidity we get in the Carolinas, there’s usually plenty of moisture to go around. Drainage is an essential component of any solution, and our teams have plenty of experience coming up with the right plan for your home – nothing cookie-cutter here. As quickly and easily as water gets in, you need a system that moves it out and away from your home just as fast.

Why Choose Moisture Loc for Drainage?

  • Local experts who understand Carolina soil and water flow.
  • Systems tailored for your crawl space – never a one-size-fits-all solution.
  • Honest recommendations focused on need, not price.
  • Drainage integrates seamlessly with other solutions like encapsulation.
  • Experience, experience, experience.

Drainage Options

Crawl Space French Drain System

Crawl Space
French Drain

Our technicians dig a trench around the perimeter of your crawl space and place a pipe around the earthwork. Next, we cover the piping with stone. Typically, we connect the trench to a sump pump, which stores the water and pumps it safely away from the house.

Interior Low Point Drain

Crawl Space Low Point Drain & Discharge

A low-point drain features pipe installation at the lowest point of your crawl space. This drain usually slopes underground towards the street, allowing water to flow out of the crawl space.

Exterior French Drain System

Exterior French
Drain System

Our team installs exterior French drains along the outside wall of your crawl space and direct water away from your home and foundation. When it rains, water flows into a pipe and moves to a lower level – such as a ditch, well, or street.

Why Choose Moisture Loc

Nothing cookie-cutter. Never a franchise.

  • Family-owned and run since 1988. Moisture Loc has served local homeowners and builders for nearly 40 years. When you work in the same community for that long, you get to know it from the ground up. That’s why there isn’t a crawl space or basement issue we can’t solve.
  • We do it right, or not at all. That means finding the real problem, fixing it the right way, and standing behind the work and warranty. It also means pulling the required permits that others skip. Every job gets its own right solution, done to the standard your home deserves, and we demand.
  • You can breathe easier. When 40% of the air you breathe at home comes from your crawl space, you want to know it’s clean. Our encapsulation and waterproofing solutions keep humidity, mold, and wood rot out and a sense of security in. Plus, our foundation and structural solutions preserve the integrity and value of your home while delivering the peace of mind every homeowner wants.
  • This means more to us. We’re rooted here, not spread across states or managed by investors. With one office and one team, the work stays close and personal. Every job means more when you live in the community you serve. We don’t answer to anybody but our customers, the way it should be.

Carlos was very quick to respond with an emergency issue with my listing! As a realtor I need trusted sources to get ahold of with questions and help asap when things may go wrong. Will use Carlos again! Thank you.

After purchasing my home, I started noticing cracks in the drywall, just a few months later. After finding out the house had structural issues, I interviewed several companies and decided to go with moisture lock. If your dealing with structural issues, I highly recommend Moisture lock for their expertise and customer service. Carlos, James and Scott were excellent. I am very pleased with my experience and the work they did to my home.

I have nothing but good things to say about Moisture Loc. I was referred to them by a friend/neighbor, and they did not disappoint. Carlos was thorough in his initial inspection and project recommendations. There were no surprises. I felt like Carlos was honest when he gave us a quote for the work, and that was very important to me. James came with his crew to actually perform the work, and he was equally as outstanding. The work was completely efficiently and properly, and all projects passed Mecklenburg County inspection the first time around. I couldn't be more pleased and highly recommend this company!

These guys did a great job! We had a moisture issue under the house which was messing up our hardwood floors. I had 2 other companies out and then spoke with my neighbor, who is a contractor. He highly recommended Moisture Loc. They didn't try and sell me on things that were not needed and came in less than the other 2 companies. Their work crew was on time and respectful and pleasant. The job is complete and I'm impressed. Highly recommend!

Got 4 local quotes for encapsulating the crawl space of our home. This was a no-brainer, Moisture Loc was heads and tails above all others. Dan Richert was extremely professional, clear and to the point, no up sale, and answered all questions. Everyone involved including Rich Goldman and Brandon Cook were also extremely professional, knowledgeable, and very responsive. Everything was on time. And thanks Ryan (office person) for being there and answering the phone! (seems to be a lost art these days). Highly recommend these folks!

I am a realtor working on behalf of my buyer client to source quotes for repairs. Carlos has been extremely responsive and knowledgeable about his scope of work. I appreciate his honesty in not trying to upsell me on a sump pump because I recieved quotes from multiple crawlspace companies and called to inquire further about this. He was transparent from the beginning and explained why it was not necessary for this particular property, even before I had the chance to ask him. Thank you for your efforts to earn my business. I appreciate you putting the customers needs before your own pocket and look forward to doing continued business with you!

Had a great experience with Moisture Lock. They installed Helical Piers and re-encapsulated my crawlspace. Jerry was an absolute powerhouse for installing the piers. His knowledge and skills are off the chart. The crawlspace work was great as well - Moisture Lock came in a fixed a botched job that was done by Carolina Crawlspace Pros who are now out of business. Everything is in good order now and these guys did a really great job.
