"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."

"Doug & Zach were very helpful in coming up with a creative and Architecturally pleasing design for my house renovation. Being a builder myself I truly appreciated the expertise & ideas used in the design. They truly know how to make modular looks totally custom and unrecognizable from a traditional stick built house Kent E. ERI Building & Design"

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"I?m Edison Matteo from Sunshine Estimation, based in Erie, PA. We worked with NextEdge Builders Corp for our architectural project, and I personally managed the entire process from start to finish. Initially, I had them prepare detailed CAD drawings for our project, and the quality and accuracy of these drawings impressed me immediately. Once the drawings were completed, I requested a cost estimate based directly on them. The estimate provided was extremely precise, with an accuracy of around 98?99%, which gave me great confidence in planning our budget and moving forward. What sets NextEdge Builders Corp apart is that everything is handled under one roof. From drafting to estimation, the process is seamless, reducing the need for constant revisions or coordinating multiple service providers. Their communication, professionalism, and attention to detail truly stand out. I highly recommend NextEdge Builders Corp for anyone looking for reliable and accurate drafting and estimation se"

Structural Engineering FAQs, answered by experts

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.

Generally, you can tell if a home is bolted to the foundation by checking the foundation for plates. If you see that your foundational plates connect to wood or bolts protruding from them, this means that you have a bolted foundation. However, it's always wise to bring a home inspector in to confirm if your foundation is secure.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

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.

The costs depend on the type of wood, labor, roofing material, permits, and whether additional storage or enclosed walls are included.
