"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!"

Lovett and its 60 employees have been making happy customers for 15 years servicing Oregon & Washington.

"We were one of the lucky ones to work with Lovett, County, an another Contractor on a project that we didn't want! When they got to moving our water meter and PRV, the contractor or Water company couldn't work on private property, so they hired Lovett. Where they move our PRV, it was under water. We had told them where they were putting it; that the water table is high. But, Lovett and the County said this is where it needs to go. This whole process lasted for months, I sent photos of our PRV under ice, no response but it did show up on their Facebook page, "to call if this happens to you" my photo that I had sent! I have chatted with both Scott and Gabe, plus the tech(s) on site. All (3) companies kept putting the blame on one another. I had a conference call with all 3 of them, and told them that my PRV is under 3' of water and I need help. I asked multiple times for an estimate, and no one would send me one. This whole mess started with their employee coming into our home looking at our hot water heater and mentioning where that PRV is, that we will have problems. This is in the wrong location. They did come out and move it 12", which was a complete waste of time. Again, as I mentioned it's under 3' of water. Their answer was this employee no longer works with us! Over and over! Scott told me in the very beginning, "We will take care of you, if not you can write a review". Where here I am writing a review."

Basement Waterproofing questions, answered by experts

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.
