"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."

"WE LOVE JOSH! We initially hired him to remodel a kitchen after another contractor botched the job. Josh fixed everything and got everything finished the way it should been in the first place! We have since hired him for two more jobs: pouring a concrete driveway extension for RV parking, and replacing some siding and painting the entire exterior of the house. Josh is meticulous and clearly takes pride in his work, he is super easy to work with! I HIGHLY recommend Josh, we will continue to hire him for all of our construction needs!"

"Awhile back I decided it was time to replace my old, crumbling shed. After doing a search on Angie’s List, I hired Gryphon Construction because they had good reviews. The process worked, and I must say that I’m super happy with the results I got. Not only were Akeem and company great to work with, they did an excellent job, and and I’m extremely happy with my new shed. (The only reason I’m not calling it “shop” is because I didn’t have power installed). It’s solid, has a locking door, as well as a window, and looks more like a tiny house than the shed that proceeded it. And while they were here, I also had them install a new track for a broken pocket door, which involved removing some dry wall to get at the work-out track. They did a great job on that, too, and I’m very happy with the remodel. I found them to be pleasant to do business with, as well as very conscientious, timely, and they have a strong sense of craftsmanship, which, after all, is what we all want in a good contractor. I highly recommend them!"

"We hired Patrick Concrete to install a concrete patio around the front of our house with a connection to the two front doors. Patrick and his crew were very courteous and professional. We talked with him about some specific design considerations that we wanted. He helped us with some preliminary work, made some very practical suggestions, and gave us the end product we had asked for. His price was reasonable. He started the project right away and did the pour as soon as weather permitted. I would use Patrick Concrete again and recommend them to others."

House Leveling questions, 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.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.
