"I'm finally getting around to writing a review, although the work happened awhile ago. When we noticed cracking in the walls at our house, we found three companies to call. I decided to hire the second company because they could do waterproofing in addition to structural repairs. I sure regret that decision! If I had called Ram Jack before hiring the other company, I would have been spared a two-year ordeal and the loss of thousands of dollars. Instead, I ended up calling Ram Jack for a second opinion, after problems developed with the other company. Curt and Ken (the owner) came to do an assessment of our house. They were thorough and looked at the whole picture to determine what issues needed to be addressed, rather than just trying to sell their products and services. Their only recommendations were to replace a rotting support post in the basement and to direct water away from the foundation. When I told Ken what the other company had recommended and that most of the work had already been completed, he seemed shocked but did not use this as an opportunity to trash his competitor. Other people who looked at our house were not as charitable! I think this says a lot about Ken's character. The one recommendation from the other company that I thought might be justified was to pier a corner of the house that had settled about two inches. I was ready to sign off on this work but Ken strongly discouraged me from doing it, explaining that it was purely a cosmetic issue and that future settling was extremely unlikely because the water issue had been taken care of. He told me to at least wait a year and reassess the situation, turning down what would have been a 15-20 thousand dollar job. What I did end up hiring Ram Jack to do, was to correct the problems caused by the other contractor and to get everything up to code. The City scrutinized all of the work done at our house because it was not up to code and the other company did not obtain the proper permits. Ken was willing to collaborate with an engineer and carpenter to get the job done at the lowest cost to me. Although some of the damage caused by the other company could not be remedied, I think he got the best results possible without doing more extensive repairs. Everyone I had contact with at Ram Jack was wonderful. They even offered to haul away debris left from a previous job. I sure appreciate Ken's willingness to take on a relatively small job and to step in and fix someone else's work; many companies are not willing to do that. If I ever have a need for structural repairs in the future, Ram Jack will be my FIRST phone call. I highly recommend this company."

"Jeremy was great to work with. He kept in communication all during the project and was quick to reply to my messages. The job was done quick and efficiently. It was a sidewalk repair and there were roots that had to be removed. It looks beautiful. Would not hesitate recommending him or use his services again. Thanks much Jeremy!"
