"I needed a foundation crack repaired and scheduled for Ram Jack, along with 2 others, for quotes to get that repair done. After receiving a quote from another business, to the tune of $53,000 for "other problems discovered", I had Ram Jack come out and did not tell them what the first place said. After they crawled under the house, took measurements, etc, they found nothing wrong with the foundation, advised me that I was not in need of their services, and provided me with the names of a few well-known and trustworthy local businesses that could repair the foundation crack. I cannot tell you what a relief that was and how impressed I am with the Ram Jack's honesty and integrity! They are definitely on my list of trustworthy people to deal with in the future, if / when needed!"

"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!"

"It was a dream working with Jeff. Knowing I was dealing with health issues, he took me under his wings and took care of me. Other companies I previously talked to didn't even attempt to find a solution to the problem I was having that would be affordable for me, but Jeff went above and beyond to help me. Beyond just saving me THOUSANDS of dollars, he walked me through the whole process and did tests making sure nothing was missed that might need to be addressed so when I put the house on the market again the inspectors will be happy. I just can't say enough nice things about this company, aka Foundation King, they truly care about their clients."

FAQs for concrete foundation repair projects in Lake Oswego, 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.
