"Steve came over and gave us some good news (not a foundation problem), but also gave us a reference to someone who repairs concrete for the type of problem we have. He really knew all about these issues and told us some signs to look for that would indicate a real foundation problem. Very pleasant company to deal with."

"I researched 4 companies to fully encapsulate a crawlspace damaged by flooding and rats. I also did a lot of research into possibly doing it myself so i knew what to look for. John's was the most expensive, but they were all in the same general ballpark. I was put off by some of the competitors marking insulation as "extra" and not including in their initial estimate. Insulation is required! John's costs a bit more but you get more too: John's insulated the entire floor with wrapped foam pads, dug a drain trench around the entire perimeter, jacked up every concrete pier to slide vapor barrier underneath the posts, and used proper mechanical fasteners on all of the wall insulation boards. Every nook and cranny was sealed with spray foam. The workers were amazing. They did not cut any corners. They nipped and tucked every tight little spot and never complained or made excuses. They built a plastic clean-tunnel every day and took it down down every afternoon. They did not leave behind trash. My crawlspace is clean enough to literally eat off the floor now. I would recommend John's if you want your job done correctly."

Fiberglass was drooping away from the home, removing its insulation value

"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"A technician named John did a crawl space inspection and said I had no mold and no rodents and did not need their services. He was professional, friendly and honest. i just received a quote for $12,000 from another contractor for work that did not need to be done or that I could do myself."

"Terra Firma folks explained things clearly, did the needed filling with their foam filler and patched the fill holes. All done in just a few hours. Sure beats the time and cost of tearing up the concrete, bringing in fill and re-pouring. We've referred several family and friends. Recommend TR highly."

"I cannot speak highly enough of Tom and Brad Green of Colonial Restorations. We have lived in our antique house for 16 years now, and like most old homes, some of its previous repairs were good, some not so good. Tom Green worked on this house for its previous owners, and his work was, by far, the best in the house. So, we continued to use Colonial - Tom, then Tom and Brad - as we learned the ropes about caring for an old house - our first house, old or new. Over the years, they have replaced sills and posts and beams, and rebuilt parts of our loose stone foundation. Most recently, they replaced the last original posts in our basement, (one of which was a tree trunk still with bark on it), including pouring new custom footings, in advance of our finally cementing the dirt floor. The work here is never easy - nothing is level, nothing is square - but the Greens' end result has always been beautiful - strong and made to last. Their prices are fair and without hidden costs....maybe not the lowest bid you might get, but you know it's a real bid that they will stand behind. They triage projects for us, giving us an idea of what other items will likely need attention in the next few years. We're not done with this house yet....we've never won the lottery, and there's always another repair..... and plan to use them again soon. I feel confident knowing that the next owners of this house, whoever they might be, will see the quality of the work and know that we cared enough to have the right people help us with the ongoing repair and maintenance of a 275+ year old house. I am a real person, a real customer, with no ties to the company, and was more than happy to write this review."

"Ethereal Elements provided exceptional, professional and quality work repairing my basement wall leak. Dealing with Q was very easy, he is personable and to the point. Dale, who performed the work knew exactly what he was doing, he was quality oriented from start to finish. The work was completed on 4 October, I held off writing this feedback in hopes we would have a couple of extreme downpours so I could verify the basement would not leak. Q guaranteed the basement would not leak again, or they would come out and fix it. The cost of this job was reasonable and I was able to use the discount coupon. I would hire Ethereal Elements again."

"Quality Calvary Construction did a fantastic job I was very pleased with every aspect of their work. When they came across something that wasn't included in the bid they came to me and explained exactly what needed to be done and what it would cost me. I really appreciated their integrity.

"James and his team evaluated my roof, discovered the problem, and fixed it. In addition, he informed me on potential repair locations. I had been attempting to have my roof fixed but had received no response from other contractors. I'm very glad I chose NW Builders, and I recommend them to anybody in need of roof repair."

FAQs for concrete foundation repair projects in Rainier, OR

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.

Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.

Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
