"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."

"I have used HomeWork for several different projects in the last two years including a full bathroom restoration, a pergola restoration, a custom stair banister and a custom fireplace surround. The owner Steve Kaplan is very professional, always friendly and reasonable. He staffs each project with a team of highly skilled professionals with the right skillset for the specific project and his prices are competitive when compared to others. I highly recommend Steve and his team."

Structural Engineering questions, answered by experts

By careful planning and reinforcement to maintain structural integrity.

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.

Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys. Some of the warning signs that structural engineers check for include:

  • Dry rot

  • Infestation

  • Shifting or cracking foundations

  • Erosion

  • Water damage

  • Sagging, shifting, or damaged walls, ceilings, or roofing support

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.

Yes, unresolved damage can decrease property integrity and market value.
