Give water beneath your home a clear path out. An interior French drain collects crawl space groundwater and directs it to a sump pump or suitable outlet.
An interior drainage path collects water along the crawl space perimeter.
A crawl space French drain collects water along the interior foundation perimeter and gives it a controlled route to a sump basin or other designated outlet. The drainage path, filtering material, and slope are planned around the space beneath your home.
Water can enter around the foundation, through openings, or from a plumbing leak. We inspect the source before recommending drainage. CB’s French drain service is an interior crawl space installation, not an exterior yard-drainage system.
Water, odors, and changing floor conditions are reasons to look beneath the home. They do not all call for the same repair.
The drain, filtering material, sump connection, and outlet work as one system. The recommended layout is explained in your written scope.
We identify water entry points and install drainage along the areas where water collects.
The inspection determines the route, elevations, and connection point. Drainage materials are selected for the crawl space; we explain the recommended system rather than assuming every home needs the same layout.
The drainage system is surrounded with gravel and the filtering materials specified for the installation.
Gravel supports water movement around the drain. Filtering material helps limit soil and debris entering the system. These details support performance, but they do not make a drainage system immune to blockage or maintenance needs.
Collected water is directed to a sump basin or suitable outlet, then carried away from the foundation.
Where pumping is needed, we assess the basin, pump, and discharge route together. CB uses Pro Series sump pumps for standard sump-pump installations. The exterior discharge work and any related repairs are explained before installation.
The inspection connects water collection with ground-moisture control, air humidity, and ongoing system care.

Crawl Space Brothers encapsulated my crawl space several years ago (including installing a french drain, sump pump etc.). They did good work initially and have been readily available to address maintenance issues that have arisen since then.
Oliver and his team did an incredible job installing a dehumidifier and French drain in our crawlspace! They went above and beyond! Oliver did a great job communicating and explaining everything to us and showing us pictures! His friendly service did not go unnoticed. We could not have been more pleased and will definitely be using them for any other crawlspace needs. Thank you Oliver and team!!
Had crawspace encapsulated and small French drain put in the crew came in knocked it out and no mess left behind.
Great group of guys and did excellent work with the French drain and pump with backup battery at our house. Communicated well and honest with their work. Very happy with the work they did and will be recommending them to my friends and colleague. Thanks Devon and crew for your hard work!
We were very impressed by the services we received from Crawlspace Brothers! We moved into a home that had nothing in the crawlspace that was needed. Because of this, we had some areas that needed mold remediation and these guys did it ALL! They repaired our crawlspace door, installed a french drain system, installed a Sump pump, encapsulated the crawlspace properly, and did mold remediation! They even went out of their way to take care of a smaller job that would have normally cost us extra with the A/C company. They went above and beyond. These guys are not only professional, but they were kind and enjoyable to work with. I recommend!
