"This has been one of the worst experiences I have ever had with a business. I had work done on a crawl space and the replacement and addition of a backup sump pump. The work was scheduled to be completed all at once. On the first scheduled day/time, no one showed up. I texted the scheduling team and after approximately 3 hours it was determined that the technician was not going to be able to make it because he was still working at the previous days job. On the second scheduled day, it was determined that measurements were not accurately taken for the crawl space so that work could not be completed. They were able to install the new sump pump and the backup pump. However, they did not schedule the electrician to install the correct outlet. The third scheduled day no one informed me it was on the schedule. The only reason I knew about it was because the technician actually called to say he was not going to make it. The fourth day the electrician came and installed the outlet. The fifth day the technician could not do the work because the plumber needed to move a pipe had not been scheduled. The sixth day the work was finally completed. After taking so much time off of work, I asked for a discount which I did not receive!!!!! It is very sad because I have used them before and was very happy with the quality of the work. I will not ever use them again and I would recommend anyone who is considering using them to look elsewhere. There are a lot of quality b"

"Had Betts Structural Engineering come and look at the foundation of a house we were in contract on. Josh came out and was professional and informative. He informed us the foundation was failing and explained what needed to be done. He throughly explained everything and told us how we could do it ourselves for much cheaper than a contractor could do it. In the end he saved us from a long and expensive process if we proceeded with the house."

"My first encounter with United Structural Systems company ( USS) was last year, when I had to face the decision which company I go for foundation repair at my house in West Virginia. It was equal bids on my project from two companies USS and Alltek. Unfortunately for me, I made the decision to go with Alltek Environmental Services company at that time. Foundation repair was finished in August 2019 by Alltek (please read my review, that I placed separately for Alltek). 48,000 dollars payment later foundation been done. I finally be able to place my house for sale this year and come to realization, after inspection is done on the house, that it is a presence of water leak in the storage area. I could not believe, how it is possible, when the foundation repair was just done 8 months ago. I guess, things were not done properly after all. After numerous attempts to contact Alltek company, I finally be able to get the response with another promise to “fix it” in the amount of $9,200 or later for free…if I take off my review of their company from homeadvisor.com. Lack of professionalism, poor craftsmanship and PR was major disappointment for me. To be honest, after I been treating inferiorly by Alltek, I did not have any desire to go back to the same company. I was looking for second opinion how to resolve these issues. I decided to reach out again United Structural (who I was hoped to remember me from last year) and explain my dilemma. Bobby K. (Sales Manager for USS) come to the rescue! He was willing to give me his unbiased opinion on the situation. Bobby K, “commander in charge”, went to the house and informed me, that “downspout lines were never installed, the part on top of the ground went nowhere and tie back patch was poor quality”. Simply put it, Alltek did a mediocre job. I immediately made the decision go ahead and proceed with United Structural Systems company for repair of the mistakes. I cannot say enough praise for the USS company and manager Bobby K. This re-du project was done in timely matter, communication was superior ( needless to say I live out of state and it was never an issue), area after the job was clean up to perfection and…the garage/storage area now look dry bone and beautiful. Awhhhh... maybe I should not sell my house after all?! I have a buyer on the house, and I am closing in 2 weeks and can say with all honesty, I could not do that without United Structural help. It was exceedingly difficult situation for me, and it was resolved by USS company with flying colors. Thank you again USS. I recommend you without any hesitation!!! Your company should be proud of to provide such an excellent service and have knowledgeable, competent and skillful experts. Lana Y, Rochester, NY “We are NY tough”"

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.
Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.
The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:
Do you have experience working in my specific area?
Do you have professional indemnity insurance?
What will your structural report cover?
Do you charge a flat fee for a structural report or by the hour?
How long have you been in business?
Do you have a list of customer references?
Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.
Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
