"The work went very well. Lou is very knowledgeable, professional and easy to work with. He inspected my house thoroughly and explained my concerns in great details. He went beyond and explained some of the common non-structural issues on an old house. He also suggested on the proper ways to fix them.

"We had 2-3 years of constant road work as a result of storm Sandy (gas line and water line replacement) and there was a crack that expanded over time in the living area on the second floor. We needed to know if it was structural or cosmetic. Anthony arrived on time and began to examine the crack as well as take measurements to determine any significant changes. He was familiar with the land issues in this area, which I appreciated. He explained as he went along and also went to every room in the home and outside for any other evidence of cracks. He was extremely thorough in his inspection and advised how to correct the issue. In addition he also gave tips regarding procedures for any renovations on the property which was extremely helpful. There was a fee for the inspection and an additional fee for a written report. I would definitely hire again if I have any issues."

"Neil was thoughtful and took his time to look at everything we wanted to show him. As he looked around he also made verbal suggestions on things that needed to be fixed that was not necessarily a part of the structure of the house, but to be safe; that was appreciated."

"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."

Structural Engineering questions, answered by experts

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

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. 

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.
