"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!"

"I am a contractor that has used ZS design for years now. Every job that I have done ZS has been available on a very level available. Their knowledge goes beyond just providing drawings. They are willing to work with you step by step as a question come about and any issues during the build occur. It’s nice to be able to make a quick call and they are immediate available. Highly recommend their services to builders/contractors and especially home owners who at times have trouble finding that necessary first step to begin their projects."

"I hired Mr. Csak as a consultant to advise me on structural improvements for my home. He did an excellent job. He had a very organized approach. We walked the exterior of the property first and along the way he pointed out all the key issues. Then we did the same with the interior. Louis didn’t just focus on the site of the proposed improvements but he evaluated the entire property, so that he could give me reasoned, detailed advice about my project. He understood the big picture, but he also got down on his hands and knees to take very precise measurements, when necessary. He was very focused on my safety in the home and made sure to test for radon, even though that was outside the scope of the engagement. Since Louis is a professional, licensed engineer you are getting someone with deep technical expertise who also has years of practical applications. Louis is very honest and forthright. He is a true pleasure to work with and I would use him again. I recommend him most highly."

"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."

"We are very happy with Lou. Not only is he very professional and pleasant, he actualy advised us on a number of aspects of home renovation. We were especially impressed and appreciative that Lou didn't just walk away after delivering his drawings, he kept in touch and followed up on the contractor's work. As a result, some crucial issues were picked up and remedied. Also, Lou is very straightforward and honest. He doesn't charge a fee to come out and scope out the work for an estimate (unlike others who contacted us) and his rates were very reasonable. We would highly recommend Lou."

Structural Engineering FAQs, answered by experts

Most load-bearing walls are exterior, though they can also be interior.

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

Absolutely, as it ensures designs are viable and won’t compromise structural integrity.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.
