Please do research before you make a $30,000 to have hire a company to repair your foundation, working with them is one of my biggest lifetime regrets."

"We have used MTU Services LLC twice in the last 3 years. Two projects involving extreme foundation repair for our home in Spokane, WA. Mark and his crew are OUTSTANDING in every way! MTU has old fashion values, no price gouging, detailed bids and the crew is excellent in communication with the home owner while on site each day. Our major repairs took months because the original builder in the 1950's did not put in appropriate footers and a portion of our house began to sink. MTU also completely gutted a basement room that was compromised, jack hammered the concrete out, installed new metal ceiling beams, posts, dug new footers, metal mesh on the floor, poured and leveled the brand new floor. The hardest working real men I have seen in decades and no complaining what soever. Mark is great in keeping in touch with home owner on any questions, concerns, and is excellent on educating the homeowner along the way. One of the best companies I have ever had the pleasure to work with!"

At Ram Jack West, we treat customers with respect and care. If you notice cracks, damages, or other issues with your foundation, our team is ready to help. We have innovative systems that have been refined over our 40+ years of experience.
"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."

Industry experts typically recommend having your foundation professionally evaluated every one to three years, complemented by personal visual checks twice yearly. If you notice potential warning signs like widening cracks, door alignment issues, or unusual moisture patterns, schedule a professional assessment right away, regardless of your regular inspection timeline. Maintaining this schedule helps identify developing problems before they require extensive repairs.
Be vigilant for wall or floor cracks (particularly those wider than 1/8 inch), doors that suddenly stick or won't close properly, noticeable floor slopes, and gaps appearing between walls and ceilings. External indicators include water pooling near your foundation after rainfall and visible shifts in foundation walls. These symptoms often signal foundation movement that should be professionally evaluated to prevent escalating damage.
Standard insurance policies typically classify routine foundation inspections as preventative maintenance rather than covered services. However, if your foundation sustains damage from a covered incident like a plumbing failure, your policy might include assessment costs within the claim. Review your specific coverage details and maintain thorough documentation of any foundation issues to support potential claims for qualifying events.
Search for professionals with relevant structural engineering credentials or specialized foundation inspection experience. Verify their licensing status, insurance coverage, and client references before scheduling service. Ask detailed questions about their experience with your specific foundation type and what their inspection process entails. Obtaining multiple estimates allows you to compare both qualifications and pricing to select the most appropriate professional for your specific foundation concerns.
