"Purchased a 1906 home in North Portland with an uneven foundation that had been patched for 60 years, but needed serious stabilization work. I contacted multiple foundation contractors in the greater-Portland area and Ram Jack was the only team that provided a full worse-case estimate that included everything that I may need to permanently stabilize the home's foundation. Other contractors' estimates were higher, omitted some of the features of Ram Jack's estimate, and involved greater excavation work around the home. While I was collecting estimates, I had multiple contractors check the levels on the house and could see the home was continuing to sink as much as half and inch in some areas within only a few months, so I knew I had to do something soon as the hotter summers are causing significant erosion to the clay soil in north portland. After paying the 50% down payment, I was quickly in touch with multiple project managers and structural engineers who were able to answer my questions as the work plan developed. I work from home and have two cats, so I was a bit worried about the noise and needing to leave at certain times during the work. Ramjack devised a plan of installing 12 helical piers from the basement and 2 outside for a small crawl space area as well as replacing most of the piers in the basement that had water damage. During the excavation and pier installation, I didn't have to leave my house at all, my cats were fine, none of the utilities ever needed to be turned off and none of the neighbors said they heard more than the hum of the generator outside; insane professionalism. The work team kept me informed at every step of the excavation and pier installation and was able to recover an inch of lift with only a few drywall cracks that I patched in a day. I could have gone further, but wanted to avoid any potential damage to the sewer pipes and stay within my budget. During the lifting, I was standing with the lead construction manager who kept me informed of every risk as we lifted the house bit by bit. During the excavation my basement looked insane with mounds of dirt everywhere, but the construction team cleaned everything flawlessly; all I had to do was a quick mop and the basement was good as new again. Overall had a great experience with RamJack; the 20 years in business shows, most everyone I dealt with had been working with them for years; the construction manager had been doing pier installation for 15 years. The work was expensive, but cheaper than the other local contractors, and certainly way cheaper than replacing the entire basement foundation. Ramjack was even able to take a few grand off the intitial worse-case estimate for solutions not needed. Glad I was able to repair my 120 year old home; here's to another 100 years. Big thanks to Pancho and Stephen, as well as the structural engineers and project managers; I'm very happy with the work."

"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."

"There was some miscommunication between the dispatcher and I but the plumber that came to my house explained the issue and rescheduled me for the weekend. I explained the urgency of filling in the trenches and he accommodated my schedule, he was great to work with. He spoke very highly of his company, not something you hear everyday from employees!"

"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!"

"Overall, this job was basically all done by us coordinating with the subcontractors, who were all very nice. The owner who we hired however was disorganized, rarely around, never did any kind of inspection on the work done by the subs. Tried to sell us a window that we couldn't install because it wouldn't have been to code, then after we got the new one ordered and installed, he left the old one on the side of our house for weeks until we said we were going to take it to the dump...overall, the job looks pretty good, but a lot of little issue we had to have another contractor fix to finish it.

"Eugene and his team were very professional and did a great job with my kitchen floor. During the demo part, they ran into some unplanned issues with the flooring, and then later with the tile itself but they always made it work or suggested the best options to move forward. The job was completed on time and the finished floors looks great."

House Leveling FAQs, answered by experts

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

Most states and municipalities don’t require concrete mudjacking companies to carry a specific license, but they usually need to have a general contractor’s license, and they should be fully insured. The only exception is if the mudjacking company provides foundation repairs as well, or if it offers mudjacking for home foundations. In that case, they will typically need a foundation repair contractor’s license. You can check state requirements and then use Angi’s license lookup tool to confirm that a company is properly licensed to provide mudjacking services in your area.

Costs range from $500 to $1,500, depending on the size and condition of the area.

Many contractors offer warranties for their work. Confirm terms before starting the project.
