"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."

"Excellent customer service throughout from initial contact through completion of work. The professional crew came up with some creative ideas for my complicated exterior water drainage problem from malfunctioning gutters, and they cleaned out my crawlspace and added a new vapor barrier. Top notch work, they did a great job of cleaning everything up, much better than I expected. I especially enjoyed not being up-sold on work I didn't need, such as a sump pump and trenching for water that wasn't there, as another company recommended."

The guys at Guardian Foundations and Construction did an AMAZING job removing and replacing the damaged posts and beams and getting my floors leveled again! They were punctual, personable and professional! I highly recommend using these guys to fix up your home! Thank you Guardian!"

"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!"

"Terra Firma's estimate was some $20,000 more or 8x higher than everybody else. Their recommended repair plan was unanimously thought every other company thought as ludicrous, alarmist and way overpriced."

FAQs for concrete foundation repair projects in Portland, 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.
