Expert French Drain Installation

Water always pools at the lowest point it can. In most Carolina homes, that’s the crawl space or the area right outside the foundation, which are also two of the worst places for water to collect. Out in the yard, pooling water turns usable space into a muddy mess that takes days to dry. A French drain redirects this water elsewhere.

Moisture Loc has installed French drains across the Carolinas for decades. We know how this region’s clay soil, frequent storms, and older homes interact, and we build French drain systems that hold up to all three.

French drain details to know:

  • Redirects water away from your crawl space and foundation
  • Helps yard drainage and prevents puddling
  • Protects against puddling, moisture damage, and mold
  • Serves as a key component of crawl space waterproofing

What is a French Drain?

A French drain starts with a trench that our technicians dig around the perimeter of your crawl space or outside your foundation. They then place a perforated pipe in the trench and cover it with stone. Typically, we connect the trench to a sump pump, which collects the water and pumps it safely away from your house or trouble areas in your yard. A properly installed French drain can and should last decades.

Without a French drain, pooling water can:

  • Create an ideal environment for mold growth
  • Cause wooden joists and beams to rot
  • Create musty smells that permeate your home
  • Damage your yard or render parts of it unusable
  • Create havens for termites and other infestations

Whether it’s part of a larger crawl space waterproofing project or installed to protect your lawn and yard, a French drain can be a long-term lifesaver for your home. Learn more in our guide to French drain systems.

Where French Drains Work Best

French drains work both inside and outside your home.

Crawl Space Drainage

Crawl Space Waterproofing

When Moisture Loc waterproofs a crawl space, French drains can play an integral part. The purpose of the French drain is to redirect water before it can pool on the ground or soak into wood and insulation.

Foundation Protection

An exterior French drain runs along the outside of your home’s foundation, pulling water away. Foundation damage is one of the most expensive repairs a homeowner has, and a properly placed French drain is one of the most affordable ways to prevent it.

Low Spots in the Yard

A French drain can route standing water in your yard to a safe expulsion area. Learn more on our Yard Drainage Solutions page.

Signs You May Need a French Drain

  • Puddles along your foundation after it rains
  • Puddling, dampness, or wet spots in your crawl space
  • Visible mold
  • Musty odors coming from below the house
  • Soggy patches of yard that take much longer to dry

If you see any of these symptoms inside or outside your home, it's worth identifying the issues before they turn into bigger problems. Learn more about what to look for here: What is a French Drain and How Does it Work: A Charlotte Homeowner's Guide

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.
