"was incredibly kind, detailed, and honest. He Hazem truly cared about doing the job right—not about money. He even jumped into the attic without a ladder to make sure every detail was checked and confirmed the wall wasn’t load-bearing. Highly recommend!"

"If I could give this company a negative star rating, I would. This is by far the worst company I’ve ever dealt with, of any type, in my entire life. I had a settling garage and in November 2019 I contacted Robbins to see if they could fix it . After looking at the project, they told me that they could not consider proceeding or giving me an estimate without my obtaining an engineers report. They referred me to an engineer who prepared a report (for $4000) and then provided a copy to me and to Robbins. In January 2020, I contacted Robbins to see if they could give me an estimate based on the report. They said they would get back to me. At minimum, over the next six months, I had at least 10 communications with Robbins (not an exaggeration), either over the telephone or in writing trying to determine the status of my project. During that time, when I contacted them, they either didn’t respond to my communication or told me that they were still “working on it.“ Finally, frustrated after six months, I asked to speak with a supervisor. I explained the situation, he apologized profusely, and told me that he would look into the situation, and get back to me the next day. A week went by and I heard nothing back from the supervisor, as promised. So, I ended up calling the supervisor and asked him what he found out. He told me that based upon the engineering proposal, “this was not a project that they would do.“ I asked him why, if he had the engineering plans for six months, I wasn’t advised sooner that they weren’t going to proceed on the project. He simply said that he thought it had been communicated to me. So, eight months after contacting this company, I have incurred over $4000 in engineering fees and have to start searching for a foundation repair company all over, after wasting my time with Robbins. Obviously, from other reviews, other people have had different experiences with this company. For me personally, I have never been treated so poorly with customer service or had such a horrible experience."

Cash M. Carr Technical Services is an engineering company that specializes in foundations repair, and open floor plan renovations.


"Josh came out for an hour to talk through how moving the staircase might go. He was polite, professional, prompt. I paid him for an hour of his time ($125). I ended up using a different structural engineer because Josh was booked 13 weeks out and I wanted to get my permit more quickly than that. His overall quote for the work was around $1000, which seemed very reasonable to me. He was patient when answer all of my MANY questions. He was very understanding and polite when I told him I would be using a different engineer."

Structural Engineering questions, answered by experts

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

Trusses and rafters each have advantages and disadvantages, so one isn’t necessarily better than the other. For example, trusses are more affordable and often come in prefabricated kits, so they’re easier to build than rafters. However, rafters are available in a variety of designs, so it’s easier to find one that fits your style preferences. Plus, if you want to build an attic at some point down the line, it’s far easier to do that with rafters rather than trusses.

Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.

Accurate measurements, sturdy materials, and seamless integration with other structures.
