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!!!"

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"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!!!!!"

"With a slight delay due to COVID, the work was very well done. Plaster repairs were completed, all furniture was moved away from the walls, the floors were covered. The colors were exactly as I requested, including the crown molding. The work was completed in the time quoted and for the estimated cost."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

Structural Engineering FAQs, answered by experts

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.

Costs depend on unit complexity, labor, wall mounting needs, and additional accessories like floating shelves.

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.

Stone, marble, and brick are common building materials of Neoclassical architecture, though you will also find wood flooring and a range of natural stone tiles. Since several home styles fall under Neoclassical architects' umbrella, a range of building materials—including traditional wood framing—will make an appearance.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
