"Our 25+ year-old French drain system in our 100-year-old basement was showing signs of failure, so we contacted several companies to get advice on what to do. Jason of AA Action was very professional and helpful when he performed his initial inspection of our basement, and had very good ideas on what needed to be done. The price he quoted for the work was also, based on what we had read, reasonable. We ended up going with another company recommended by Angi, but only because it brought up a couple of options that we had not thought of, and we felt comfortable with them doing the extra work. We were not at all unhappy with AA Action's suggestions or pricing - it's just that the other company's additional ideas made sense for our circumstances."

"JES Foundation contracts all their electrical work out to Root Electric. In the process of installing my new sump pump, back-up sump pump, and sump pump alarm system, it was determined that a new dedicated outlet could not be created due to my existing electrical panel being too small. Thus, I needed to get an electrical panel upgrade. Through JES Foundation, a date and time was arranged to have my new electrical panel upgrade installed. The lead Root electrician Andrew, and his assistant Andy, dd a terrific job installing the new upgraded electric panel. They were both very friendly, efficient, and professional. Andrew afterwards walked me through everything that was done, and answered any questions that I had. They also cleaned up afterwards very well. I highly recommend Root Electric and JES Foundation to anyone who needs their expertise."

"I hired Paul to guide me through the ridiculously complicated permitting process in DC for repairing an existing exterior stairway in a historic district. Before engaging with Paul, the city was telling me I needed to demolish the stairs and rebuild them to code. I worked with an architect and it became clear that it was impossible to bring them up to code. Still, the city refused to back down and said the stairs couldn't be repaired. I then hired Paul, who recommended a number of improvements that would make the stairs safer without demolishing them, created a report, and then convinced the city with all of the relevant code citations. It became clear that Paul was far more knowledgeable than the city officials of their own regulations. While the process was still a labyrinth to navigate, Paul helped me overcome every hurdle that the city placed in front of me. I highly recommend Paul. I wouldn't have been able to get this work done without his expertise and his advocacy for me."

"Having major remodel on lower level. Contractor tried to rope me into major work (and project delay) suggesting normal cracks on cinder block walls indicated a foundation issue. When I pushed back, he put project on hold stating I needed a structural engineer to certify. I called the first two people on home advisor locally and Omid got back to me in 2-3 min, was at my house within an hour and delivered a certified report within 3-4 hours. He listened to the situation and spoke with my contractor to hear his assessment before beginning his assessment measures. He directly pushed back on what contractor stated and provided simple solution for one crack that was more than hairline. Report was meticulous, he spoke with contractor directly, and saved this project. It was more affordable than what was suggested on average costs. While I couldn’t divorce from the unethical contractor mid project—I would have been stuck with no out without the work of Omid!"

Structural engineering services FAQs
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.
