We can help you too! Foundations First is the NW expert in home foundations, basement and crawl space waterproofing, concrete leveling, and wall stabilization.
"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!"

Based in Sublimity, Oregon since 2012, Mid Valley Excavation provides site preparation and excavation services throughout Marion, Polk, and Linn Counties as well as the greater Willamette Valley region.
"Discussed the problem with my steep gravel driveway and its condition by phone. They were very complete in describing the tasks needed to be done, and when they came out 2 days later, they had exactly the right equipment and thoroughly did exactly what they said they would do, in the time they said it would take. The driveway is now graded smooth and evenly sloped, rolled, and compacted. It is in by far the best shape in the 20 years I have lived here. All at what I consider a fair, competitive price. And the crew that did the job was a pleasure to deal with. A very positive experience all around!"

"Israel and his team were great to work with and I am really happy with both of the projects they competed for me. They replaced an old, failing retaining wall with a beautiful stone retaining wall with a French drain behind it. I showed Israel pictures of what I wanted it to look like and his team did an amazing job making my vision a reality. They were careful with my existing plants and landscaping and went above and beyond by moving and repotting a shrub that I was unable to move by myself before the work began. They also replaced parts of my backyard that had been removed by neighbors and built a beautiful new fence and gate out of cedar. They did an amazing job matching the style of the existing fence and my yard looks so much better now. I am so happy with everything and I would work with GI Landscaping again anytime!"

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.
