"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."

"After interviewing 8 contractors, Dorson Jackson was the obvious choice for our major project/home remodel, touching on every room in the house. From the very start, Dorson has been responsive & communicative, something rare and incredibly appreciated. He's not just a contractor, he's a businessman and understands the entirety of taking on a huge project for us. He dedicated an extraordinary amount of time for his bidding process, breaking the house down into zones, and then listing every single change, plus parts and labor fees for the changes, in every zone. Every other contractor gave us a one or two page bid with very few details. Dorson's proposal was a detailed 17 page document. He is EXTREMELY organized and we were super impressed with the effort he put into bidding the project. We have since hired Dorson Construction and he and his team have begun demolition. He also sent photos to us of every room in the house after demolition so we could see what he had done, what issues were found that he had prepared for as possibilities in his bid, and comments on each photo explaining what he saw after demo. Because we are not living locally, having someone we can trust with our home from far away is of the utmost importance. Dorson recently brought his son on board and we have been equally impressed with his follow up and thoroughness. In addition, Dorson has gone out of his way to help us with our permitting process, which is not part of his job and was only necessary due to failure of a third party. I can't wait to see the beauty and function he creates for us in our home to be! (Review will be updated upon project completion.) Thank you Dorson!"

"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!"

House Leveling questions, answered by experts

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.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

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

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.
