"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 had a fantastic experience working with this drafting firm. From the very first phone call, Kirsten?our drafting consultant? was clear, professional, and incredibly helpful. She explained the entire process in detail and made sure all of my questions were answered up front, which gave me immediate confidence in the team. This firm partnered with engineers and architects to get the best quote for me on a stamp for my plans after they did an exceptional job on drawing the prints that met all the requirements for permitting. Their coordination and attention to detail made the process very simple on my end. If you are looking for a highly capable drafting firm that knows how to get things done right, I highly recommend them!"
