"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."

"We are very satisfied with the job Johnathan has done on our home.. He communicates well and listens to your needs on the project. He truly takes pride in his work. He pressure washed, sanded, primed, made necessary repairs and gave it two coats of the finish paint. Paint quality was excellent. We will definitely hire him again and recommend him to friends and family."

"From the minute they got out of the truck to check our project, to give us a bid we knew they were the company we would hire. They seemed to know what we wanted by way of design and finish, before we spoke. Where other companies had said flat out “We won’t do this.” “Too much work removing old concrete.” Poor access.” Moli said, “Yes, this old concrete gotta go. But, it’s no problem. We bust it up. We take it out.” At the end of the first day all of the old concrete had been removed and taken away. At the end of day two all the forms were set. Day three was rebar and detail work making all ready for the pour. Day four The concrete was poured stamped and finished. On day five everything was picked up cleaned up and they were gone. These are good people. They do good work and they are as honest as the day is long."

Structural Engineering FAQs, 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.

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

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.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
