"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."

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"Evolution design worked with me on designing and addition for a 100 and 5 year old house. We worked on the dimensions of the addition Plus the materials. Evolution understood the local zoning which was amazing that they knew that. We have not started construction. And evolution can help pull the permits and I'm considering them for that as well. All in all it was a long project but it was done efficiently, working with several of the staff an the departments."

Structural Engineering FAQs, answered by experts

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.

A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

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.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.
