Customers say: Super punctual

"I cannot praise the engineer enough. Salesmen from many foundation repair companies quoted us about $10,000 in pier installation, whereas after taking measurements for settling and analyzing cracks found we don't need ANY piers. Also, our polyjacking estimates were all thrown out as a result of the visit, because the garage floor was fine!!! Just needed to use some concrete sealant and could do that ourselves. In short, we saved about $15,000 on work that wasn't even needed. Save yourself the headache, and call this company. Very thorough, practical and will show you with measurements how your foundation is really doing. Don't rely on foundation repair salesmen to tell you!!!"

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"I am writing this review to let other homeowners know that if they are unfortunately in need of foundation repair that the best company capable of handling the job is Advanced foundation repair & replacement. I have a two story home. The entire back and side wall had settled over six inches ( a total distance of seventy five feet). At the side of the house we have a masonry fireplace that had settled significantly as well. Then owner Frank Matyiko hooked up his exclusive unified jacking machine. Frank provided us with a licensed structural engineer that stamped all fazes of construction. He assured me that our house would be a piece of cake. He was right. Advanced leveled the back of my house along with the fireplace with his unified machine. Not a crack in the house. Not a crack in the fireplace. His team was polite courteous and most importantly fixed our problem. Price: $13,500. Thank you Frankie!!!!!"

"There work was exceptional. They were very reasonable on the price for the work performed. Scott and his crew were extremely professional and polite and worked well with us developing the final bathroom designs. I would highly recommend them to anyone interested in any home improvement project. I will hire them again if I ever need any work done at my house. Very, very impressive company and employees."

Structural Engineering questions, answered by experts

Absolutely, as it ensures designs are viable and won’t compromise structural integrity.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

Structural engineers can perform various inspections on different structures in your home. These inspections usually include a report detailing the engineer’s findings and recommendations for repairs so you can determine your next course of action for repairs, replacements, or new builds. Some of the most common structural engineering reports include:

  • Full home inspection: $350–$1,000

  • Foundation: $300–$800

  • Load-bearing walls: $300–$1,000

  • Roof: $150–$600

  • Chimney: $200–$500

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.

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.
