"Pedro is a very professional Structural Engineer. Very knowledgeable."

"Connor from Stonewall Structural Engineering showed up promptly on time. He went under my 93-year-old house without hesitation to check out the foundation issues. Within two hours he walked me through all his findings in detail and gave me some suggestions. I received a detailed, sealed report in 4 days with pictures, and multiple ways to resolve my issues. I hope to never need a structural engineer again, but I'll definitely be using Stonewall if I need an inspection again."

I am a licensed Professional Engineer providing structural engineering services for residential and small commercial projects. I work with homeowners, contractors, and design professionals to help move projects through the permit process by providing structural calculations, drawings, evaluations, and engineering letters as needed.\n\nIn-person structural inspections are available in Maryland, DC, and Northern Virginia. 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. My goal is to provide practical, code-compliant structural solutions that are clear, efficient, and tailored to the project.

"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!!"
