"We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that though ;)"

"I contacted Foundations First NorthWest and a couple of other contractors when an inspection revealed some foundation settling and crawl space damage. I chose Foundations First to make the repairs because they included more work, and at a lower price, than their competitors. I can't say enough about how professional everyone at Foundations First NorthWest was, from the first meeting with the sales rep to the constant communication with office staff throughout the project. Every step was completed without a hitch -- getting permits, engineering, the repair work and county inspections. The work crews worked quickly and efficiently on both the installation of stabilizing foundation piers, and also on the crawl space repairs. And they left the work areas in a very clean condition. I highly recommend Foundations First!"

"They came up with a list of things needed to be completed. I have decided not to have anything completed at the moment. He was professional and prompt for our appointment. Everything went very well. I would probably consider using them in the future. There was a leak in the toilet in the master bedroom. He ended up actually making it worse. My husband was able to fix this problem himself."

FAQs for basement drainage channels installation projects in Longview, WA

Expect a well-built French drain to last 30 to 40 years. By channeling both surface- and ground-water away from your foundation, the system relieves hydrostatic pressure and helps prevent costly structural damage. Choose a pipe with a quality cloth filter to keep sediment out and extend the drain’s life. A quick annual inspection and routine cleanouts will keep water flowing freely, ensuring the system continues to protect your home for years to come.

Most French drains sit two feet below grade, but depth ultimately depends on the problem you’re solving. For puddling rainwater or snowmelt, a shallow curtain drain at lawn level often does the trick. To handle rising groundwater, pros dig deeper, down to the footing, and run the pipe beneath the basement slab. A drainage contractor will determine the optimal depth for your specific soil conditions and water issues.

A properly installed interior French drain captures water at the slab, channels it to a sump pit, and directs it safely outside, preventing basement floods before they occur. Because the pipe sits just under the floor edge, a plumber can reach it easily for cleaning or repairs. Pairing the drain with a reliable sump pump gives you the best long-term protection.

Hire a contractor who installs drainage systems every day—typically a foundation specialist, drainage contractor, experienced landscaper, or plumber with waterproofing experience. These pros understand slope, soil, and local codes, and they have the equipment to trench safely around utilities. Ask for references and photos of recent jobs to be sure they can design a system that keeps water off your foundation for decades.

Once the drain is in, patch the yard by reseeding bare spots or replacing plants the crew removed. Inside, look for ways to add value—finishing the basement or upgrading interior waterproofing while the space is open often costs less now than later. Schedule a quick annual checkup to flush sediment and confirm the pipe and sump pump are clear. Consistent maintenance ensures the drain functions properly and protects your investment.

Most policies don’t cover the cost of repairing a French drain itself, but they may provide coverage for water damage if the system fails. Coverage varies by insurer, so be sure to read the fine print or contact your agent before any issues arise. If you live in a high-risk flood zone, consider a separate flood policy to close the gap. Knowing your coverage in advance helps you budget for repairs and avoid unexpected costs.
