"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."

"Our house is almost 130 years old, so we needed to have some foundation stabilization done. The company was a pleasure to do business with. From our initial consultation and beyond, every contact was courteous and knowledgeable. On the first day of the project, after removing the dirt to see the foundation, it was discovered that the existing foundation was not sufficient to support using the helical piers according to the building inspector. The dirt was all replaced and it was arranged to come back out and give me a quote for a different process using smart jacks. Due to circumstances at my local building department, the new job had to be postponed until a new permit could be obtained. Once that was done I was rescheduled and the job was completed in a day and a half. When the building inspector came to sign off on the permit, he raved at what a great job they had done. I would definitely recommend them to anyone who asked."

"We hired Rene and his team to replace our fence and were impressed with their attention to detail and appreciated the advice they gave us to extend its longevity at minimal cost. We were so pleased with the finished product we asked them for a bid on interior painting. It was a long week for our 3000 sq ft home, but they protected every inch, painted every inch with consistently clean lines and repaired all the holes and areas our dogs had chewed on. This is a crew that takes pride in their work and craftsmanship."

"Job took two weeks end to end. The job was complex and involved tree removal, demolition, and then construction. Alex let us know what to expect and raised issues and decisions in an efficient manner. Noe and Gildardo were punctual, hard working, and took great pride in their work They worked through some wet and nasty weather and it didnt slow them down. The precision stone cutting they performed to build the wall properly really made a difference. The end result is amazing and we are very happy with the result."

"It was great! They repaired the duct work and return air for our HVAC system. They did the general inspection for everything and then came out and did the work. While the work was being done, I noticed immediately that the AC started running right again. It was amazing! We were sitting in 90 degree heat with basically no AC and they fixed it."

"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!"

"Well, it's fixed. A learning experience ? get many bids and make sure the company wants your business. Pros ? Technicians were polite and respectful of my home while I worked in meetings all day. ? The pooling water issue in the basement was resolved, and the floor is now dry; the work was ultimately completed. ? Initial estimate visit was free, but not thorough ? Senior staff came out later to apologize and review the work. Cons ? Pricing was far higher than industry norms based on later bids. ? Avoidable scope changes and price increases after work began; two other plumbers said the job could have been done as originally quoted. ? Communication issues (delayed quotes, unclear explanations, forgotten site details). ? Work quality/finishing didn?t match the premium price; two professionals asked if we had done the work ourselves. Added pictures because I don't know plumbing, so you decide if you'd want this. ? Extra fees add up: 10% financing fee (Synchrony) and 4% credit card fee."
