"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."

"West Lake Construction removed existing roofing shingles on my large house ( 63 squares!) and installed architectural composition shingles. They had to replace ten sheets of new CDX plywood. The boss was Tyler Weston, who knows his roofing. He was always nice to work with. His crew was hard-working and knowledgeable. He kept on budget. They cleaned up really well. I highly recommend this company."

"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!"

"Great overall experience. Ethan worked with us to find a siding and gutter solution that worked, and responded to all out questions in a timely manner. Very happy with the final product, the exterior of the house looks beautiful and modern and not 1970's anymore."

"The work itself and the work crew were excellent and that part is a definite A. However, I did not receive the same level from the sales and admin areas. In sales I was repeatedly given inaccurate information. At the end I was due a refund of $300+ and it wasn't given to me until I phoned and told them I was supposed to get it. If I hadn't complained, I wouldn't have gotten the refund. They apparently forgot about it. But...as for the quality of the actual work, they are the best and I'm very impressed with the work crew."

"It took nearly 2 weeks to get someone out to my house, but the gentleman arrived early, was courtesy and of the 5 businesses I called they are the only ones that called back. He seemed experienced and knowledgeable. We had some miscommunication however, and about about a week later the same gentleman and his manager came out. They looked at my basement and the outside spaces and sat down with me and walked me through their whole product. At all times they were very polite and informative. I would absolutely work with them if the price had been closer to what I had in hand. I was not aware that really what they were offering was a whole system and there isn't a good way to do only part of the system or do the install in pieces. I am only having issues in one place right now, so completely doing my basement felt like a little much at this point.  Furthermore, their focus is not on keeping water out, but rather managing it once it gets in. The high price point/scope of the work combined with a financial setback that made going beyond the amount I had already saved not really an option are what stopped me. They were great to work with across the board. A year or two from now with more money and potentially more moisture issues I will probably be giving them a call."

House Leveling FAQs, answered by experts

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.

Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.
