"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."

"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

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.

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.

Through detailed analysis of load paths, materials, and existing damages.

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.

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.
