"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.

"Chester made all the arrangements, though we did some shopping around ourselves beforehand. He told us which granite supplier/installer (of those we had already visited) he preferred , and why he felt that particular supplier/installer was his preference. He also pointed us toward his preferred tile shop ... having used Chester previously for another project, we trusted his judgment on this. He met us at both the tile shop and the storage yard of the counter top supplier to not only help us pick out what we wanted (granite design, and tile color/pattern), but also arranged for the consultant at the tile supply shop to meet with us at the same time. He also pointed us toward a plumbing supplier for our sink ... again, one of those suppliers whom we had already visited as part of our preliminary research during the earliest phase of our decision-making process to undertake this countertop re-do project. Once we selected all of our primary components (granite slab, tiles, sink + faucet), a start date was set, along with an expected finish-by date. Demolition took less than 1 day. Somewhere along the 2nd or 3rd expected day of work, a day (or part of a day) was lost (can't remember why) - but that did not impact the completion of the project. I had two concerns going into the project. One was whether the existing cabinet frame would support a new, much heavier counter top. The original counter top was a laminate ... probably not 1/10 the weight of a granite top. Chester said that he would have additional structural supports installed to help with that added weight. The other concern I had was about the sink we wanted to use ... the manufacturer's specs for the size of cabinet opening we would need for the sink to fit, indicated that we would not be able to use the sink we wanted, and would have to get a smaller one, which in this case would be significantly smaller if we wanted to stay with the same sink material (granite composite). Chester was quite certain that the sink (we wanted as our first choice) would fit, even if it meant a little shimming here or there. When it came time to install the sink, it dropped right into place without any adjustments needed, as Chester had felt it would ... another example of his judgment being correct. In the end, the final cost was a bit more than what we expected, but everything looked great, Chester was always available - just a phone call away, if needed; the job was done in a professional manner, and clean-up every day left the adjacent areas of the house completely livable."

"Charlie came to the house and gave me a fair quote for exactly what I was asking for. He was flexible throughout and had great communication. His crew was gracious and respectful of our home. They finished in the time he had quoted even with a few additional add-ons. We were very happy with our basement remodel and will use Charlie in the future as the need arises."

"He was very helpful and aware of all that I needed to get my project going. Thank you Peter so much for all your help."

"Evolution Drafting did a great job modifying my existing plans and updating for Arizona codes and took care of the structural engineering as well."

"Excellent professional!He did attention all details was important to us .He’s job is amazing!You can trust !We love our accent wall!We’ll definitely going to hire him again on future projects."

Very well.  I feel so comfortable about the stability of my home.  Jim, the owner of the company, was always looking for the best and most reasonable way to solve a problem.  His crew was hard working and came to work when they said they would (except for the rainy periods of course).  The house was empty so they stayed at my home (so they could be close to the job) and kept very good care of it.

 It was an expensive repair but I believe I could not have found a better crew for the same price. Since I was out of state much of the time, they kept me informed at every step, which is helpful when you can not be there.
I definitely would recommend them for waterproofing but I was most impressed with their ability to do the structural reinforcement."
