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!!!!!"

Scott and his crew were extremely professional and polite and worked well with us developing the final bathroom designs.

Structural Engineering questions, answered by experts

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.

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Costs depend on material choices, labor, and the extent of structural modifications.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.
