"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."

"Michael is very detail orientated, but just as important he came up with design concepts that I could have never imagined. I used him on a cabin addition and the design was fantastic. I highly recommend him for your next project."

"I was very impressed with the quality and the timeliness of Doyle MoneyTree?s work. He was very patient as there was a lot of back-and-forth with changing design, materials, etc and he was understanding when it came to waiting for review before moving forward with each milestone. Would gladly work with him again if a similar project presents itself in the future!"

Structural Engineering FAQs, answered by experts

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

Yes. Foundation walls are always load-bearing.

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.

If you intend to do the majority of the work yourself, you can pay to hire an architect or a structural engineer to ensure your home remains structurally sound. They can help with the planning to make sure everything is up to code and safe for your family. On the other hand, if you’re not sure your home will be completely safe when you’ve completed the project, let a pro do the job.

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