I had a large hump in the center of the dining room. Pat reviewed the entire home asking lots of questions and looking at everything about the home. He suggested that a tree root was pushing up on the floor and recommended cutting into the floor in the area of the hump. After cutting through the floor a 6-inch diameter tree root was found and removed and the floor patched. Thanks for being honest and saving me THOUSANDS of dollars. When I have a problem, I will only use Ram Jack of Arizona.

Tim S. came out to my house and took measurements and information needed to secure my homes foundation. He then sat down with me and explained all information so that I could understand what was happening with my home. Tim S. and Ramjack and Straightline employees were great to work with. Having to place piers under your home is extremely expensive and I would not have gone with a company that I did not trust. I would recommend them to everyone. Thank you for the great job done.

I had several companies come out and evaluate my home in Tempe Arizona. The cost for repair ranged from $24,000 for installing piers around the entire home to $15,000 for half of the home. Pat came out and did a systematic detail evaluation of the home. He was able to sit down with me and explain what was going on with the movement seen in the home and prove it by the data he collected. After having an engineer review and meet with Pat on the property, he agreed with the assessment and repairs were made to my rental property saving me over $14,000. Thanks again for a great job and going the extra mile.

I am very impressed with Ramjack. Kevin came to our house to look at our concrete window well that had sunk on one side and he explained how they could raise it with a helical pier. The 3 guys that came to do the work did an amazing job. After removing flagstone and digging 6 feet down, they lifted the sunken window well, returned the dirt, tamped it down and then re-laid the flagstone steps. Everything looks good as new! Taylor scheduled the project and took the deposit and balance payments and was always friendly. Everyone at Ramjack that I dealt with was very professional! I highly recommend Ramjack!
I have had a long and rewarding working relationship with Straight Line Construction on multiple residential, commercial, road and bridge projects. They have fantastic crews and the capability of taking on large complicated projects in new construction, foundation repair, deep foundation construction, excavation shoring, landslide mitigation and slope stabilization.

Straight Line Construction did an amazing job leveling my driveway and front porch. They are very straight forward and honest, and didn't try to con me into other work that wasn't necessary like 2 other companies tried to do! Their estimates are reasonable and the mud jacking done by Chad looks fantastic. I can't recommend them highly enough! Thanks again Kenny and Chad!
I had pulled the carpet up and found a crack running around the perimeter of my home and it worried me. Pat came out took measurements and reviewed the home. He took his time and explained how the floor stem wall and foundation was constructed and even had diagrams that explained the construction. He also explained the cracks in the homes floors that were straight lines and turned at 90 degrees and what they were. Everything he said made sense and put my mind at ease. What made this so great is that another company was trying to sell me thousands of dollars of repairs and could not explain anything they saw in the home. Pat, thanks for your honesty.

The foundation repair specialists (Ian and Tim) who came to our house today were fantastic-- knowledgable and very helpful, answering all of our questions and explaining many things clearly to us in ways that we easily understood. They were also really funny too, making the whole experience enjoyable! They demonstrated their honesty in directing us that we currently do not need foundation repairs (we wouldn't have known otherwise), and they taught us what to look for in the future. They will be my go-to people in the future if I need, and I would highly recommend them to anyone who needs foundation work.

Ram Jack of Colorado resolved a long-standing problem with my home. Before Ram Jack, the patio and two columns supporting the roof were failing due to a non-retaining wall owned by the County. Ram Jack was one of four companies interviewed to restore the structure of my home. When Patrick Harmsen provided solutions through helical piers for the columns and low-pressure mud jacking for the concrete slab, I was delighted to have a solution--and a cost-effective one, at that. Patrick Harmsen, Ram Jack’s estimator, knew what would work, and proved completely dependable, always responding to questions in a timely manner and with a wealth of experience. Jonathan Struensee, in charge of a crew of seven, perfectly coordinated what other companies had said would take at least two days. In four hours the job was completed and the site completely clean. Jonathan answered all questions and kept the job moving at an amazingly fast pace. When four large trucks showed up, I thought perhaps Ram Jack was more accustomed to huge jobs. Jonathan reassured me that Ram Jack routinely handles residences. Every interaction with Ram Jack of Colorado has been one of integrity. Everyone did exactly what they said they would do, from the office through job execution. I am recommending Ram Jack of Colorado to everyone.

I called Ram Jack Arizona to evaluate cracking that I was noticing in my floors and walls. Tim came to my home and took measurements throughout my home. He was friendly, knowledgeable and answered all my questions thoroughly. He advised me that my problem was heave caused by severe drainage issues in my backyard. I had a previous estimate, from another company, that advised me that piers were needed around the perimeter of my home at a cost of over $20,000. Tim advised me that no piers were needed at this time. With proper grading and removal of a large tree stump and residual roots, further damage could be prevented and may allow my existing heave to subside. The estimate for grading was much less than I had been quoted for the piers that the other company wanted to install. The grading and removal was completed in 3 days. The work men that were on the job were professional and friendly. They were respectful of my neighbor’s yards and came back to hand rake the rocks to make it look like that had never driven through the front yard. I would highly recommend using Ram Jack Arizona.
Just wanted to let you know I'm very happy with the quality of the work! The front walk and the porch look so much better and they're much safer! No tripping on uneven "slabs" sticking up like ants' earthquake damage. The "slanty" garage floor is almost like new. The big cracks are now so tiny they can barely be seen. There are no gaps under the garage door and the floor is so smooth and level I keep walking back and forth just enjoying it! The guys were fantastic; they work well together and were sooo patient with me and all my questions and comments. They also did a super job cleaning up everything, especially the yard and the street. They even raked the bare dirt to remove their footprints! (They did refuse to squirt some of that magic mud in a nearby anthill!) Tell the guys thanks, and let them know they earned 1,000 "Brownie Points." (It's a family thing we do when somebody goes above and beyond what was expected or is unusually helpful.)

All the Ram Jack personnel we dealt with were polite, professional and competent (as far as I can tell - I'm not familiar with this kind of work). They were punctual and thorough. The repair crew foreman, Ryan, was great at keeping in touch with the independent structural engineer throughout the project. He also had good respect for safety - I overheard him briefing the crew and he always set a good example. All four of the men on the crew worked very hard. I have confidence in the Ram Jack guarantee and the way it is funded through a trust. I also appreciate their contract which is clear and understandable and the way they do business. Special promotional discounts don't seem appropriate for this kind of work.
I just wanted to drop a line and tell you what a great job your team did on our house. The crew was an amazing bunch of guys - very capable, professional and courteous. Please pass this along to all of them. We’re very happy with the way things turned out. Hope we don’t need your services again, but if we do, we know who to call!

Lee was great, told me what I needed to fix my price, he was honest and the price was fair.
Very timely, professional, thorough and we were confident in their advisement. Will recommend based off experience with rep and the care they showed to our issue. Thanks, Ram Jack of New Mexico!
The excellent care and professionalism we were shown was beyond compare. Tim Appel, represented, Ram Jack of NM, with marks of high integrity. He came out to our home and assessed what we feared was a crack in the foundation in our home. He immediately assessed the areas of concern and relieved our anxiety with a complete explanation he didn’t believe we had a problem. He explained why he felt there was no reason to be concerned, we did schedule an appointment for him to return and do a water mark test to determine whether his assessment was correct. Tim returned on schedule, performed the test, and proved his initial assessment was correct. We realize that the test could have concluded either way, the reassurance that it would probably not ever a problem for us was met with gratitude. He also gave us some valuable advice as to how to ensure our property could be prepared to direct the water flow away from the home. We appreciate his concern and professionalism and would recommend him, to anyone that would be in need of foundation repair work.

About Ram Jack

Ram Jack is a family-owned business that began operations in 1968, in Ada, OK, where we currently source our piers and brackets. Back then, concrete piering was the original repair method used simply because it was the only technology available at the time. Over time, it became evident that concrete piers did not provide long-term stabilization of foundations and only provided a short-term warranty period. To guarantee the highest grade of customer satisfaction, a greater solution needed to be found.

The Ram Jack owners embarked on a research program to develop a foundation repair system to stand the test of time. The U.S. Patent and Trademark Office first issued a patent to Ram Jack for its foundation repair system in 1985. Over the next few years, additional refinements and patents have followed, resulting in the strongest patented system in the industry. Ram Jack driven pilings are ICC-ES recognized (International Construction Code—Evaluation Services). Ram Jack is one of only two ICC-ES recognized foundation repair companies in the industry. Ram Jack’s products meet or exceed code requirements set down by ICC-ES for both commercial and residential properties.
