"Working with CASNA Design was the best of experiences. My husband and I had never worked with an architect before. Mario was patient, answered all of our questions, and was extremely knowledgeable. He kept our mind at ease throughout the entire process and had true excitement around making our project a success. We will definitely use CASNA Design services again!"

"Damon Howard inspected the foundation of home we were contracted to buy, he found structural errors and listed them on the report. Very thorough and clear report! Took time to explain issues and recommended companies for repairs and then returned to make sure the were fixed correctly."

"Tim was very professional, he was prompt in responding to messages. He showed up on the time for structural inspection and did thorough inspection. I highly recommend him considering my earlier experiences with other structural engineers, how they carry out their inspections and never give any definitive answers."

"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."

Remote structural consulting is available in Delaware and North Carolina.\n\nTypical projects include load-bearing wall removal, beam and header sizing, additions, decks, foundation concerns, and framing evaluations.

"Everything was done in a timely manner, areas were left clean everyday and Miguel Martinez always communicated with us every step of the way. We love our new bathrooms. They took both bathrooms down to the studs, replaced the bathtub and fully tiled the tub area and the wall behind the vanity and installed vanities, mirrors, lighting and exhaust fans. In our bathroom, they removed a fiberglass insert shower and rebuilt a fully tiled shower with a bench and two niches. We would highly recommend Miguel Martinez and Smart Flooring and remodeling solutions. P.S. - During our remodeling we found some water damage to our outside wall, Miguel was able to connect us with a crew that could make the repairs we needed. All his crew were great and we really appreciate all their work. THANK YOU!"

Structural Engineering FAQs, answered by experts

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

Proper licensing and experience in residential and commercial structural projects.

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