"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 am writing this review to let other homeowners know that if they are unfortunately in need of foundation repair that the best company capable of handling the job is Advanced foundation repair & replacement. I have a two story home. The entire back and side wall had settled over six inches ( a total distance of seventy five feet). At the side of the house we have a masonry fireplace that had settled significantly as well. Then owner Frank Matyiko hooked up his exclusive unified jacking machine. Frank provided us with a licensed structural engineer that stamped all fazes of construction. He assured me that our house would be a piece of cake. He was right. Advanced leveled the back of my house along with the fireplace with his unified machine. Not a crack in the house. Not a crack in the fireplace. His team was polite courteous and most importantly fixed our problem. Price: $13,500. Thank you Frankie!!!!!"

"I was looking for someone to handle blueprints and engineering for a home in the Florida Keys. Having built homes before, I’m familiar with the process and already had some sketches with a few changes I wanted to make. I found Evolution Drafting online, and Kristine walked me through everything clearly. Lindsey was assigned to my project after a quick introduction and a follow up she was AMAZING to say the least! The initial drawings were excellent, and any changes I requested were completed within days. Compared to another project that took nearly a year, this was incredibly fast and detailed. My wife and I are very impressed. I highly recommend Evolution Drafting LLC—ask for Lindsey on your project. Truly top shelf!!"

Structural Engineering questions, answered by experts

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

Costs depend on material choices, labor, and the extent of structural modifications.

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.
