"In renovating our beach cottage in Warwick, RI we found the roof needed structural work. Building inspector required a structural engineered plan. Adam was easy to communicate with. He was timely with his plan and follow up inspection. He was also available by text and phone for questions during the project. He was great to work with!"

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

Structural Engineering questions, answered by experts

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.

Proper licensing and experience in residential and commercial structural projects.

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.

Yes, they offer plans for repairs or reinforcements to address issues.

Structural engineers specialize in all aspects of a building’s structural integrity, including the foundation. Foundation engineering is a critical part of structural engineering, so structural engineers are experts in foundation design. Many foundation repair companies either have a structural engineer on staff or one they work closely with, so be sure you look for that when deciding who to hire for foundation repair.
