All Residential Renovation Structural Inspection
"I had the pleasure of working with Structure Professionals for the renovation of my kitchen, and I couldn’t be more pleased with the results! They expertly help design the space by incorporating a load-bearing beam, transforming my kitchen into a beautiful open-concept layout that flows seamlessly with the rest of the home. They were responsive, on time, and always ready to answer any questions I had throughout the process. I highly recommend Structure Professionals, A fantastic experience all around!"

"We had a positive experience working with Structure Professionals on our remodel. Patrick was very knowledgeable and responsive to all our questions. He reviewed different options with us in great detail. Highly recommend!"
Chad R.Homeowner
It was a pleasure working with Patrick. He helped with a home purchase, where the general inspector identified some potential structural issues. His expert opinion confirmed the inspector's findings, and we'll communicate with the seller for a resolution, which could have been my financial burden without his report. The process was smooth and Patrick was quite thorough with his work. He delivered the report in ~2 days despite his recent hand surgery. Will recommend his work to anyone in the same situation.

I highly recommend Patrick. He is professional, knows his stuff, and very compressive in his analysis of our foundation and water problems. After speaking to him and his insight into our problems I trust him and am so glad I reached out to him before going with a corporate company. He offered several solutions and never did he push his own services after the analysis and he also offered the least expensive option first. This is best proscribes and ethical to the max. Thanks, Patrick!

We had Patrick come and inspect our home due to a few concerns about the structure but also in preparation for our kitchen remodel. He was professional, very nice, and full of great advice!

I consulted Patrick at Structure Professionals while purchasing a home under contract to assess the structural integrity of a detached garage with foundation cracks and to determine the best way to attach a deck to the house. Patrick was incredibly knowledgeable, personable, and highly communicative. He provided a thorough evaluation of the garage, offering clear recommendations for necessary repairs, and explained the optimal deck attachment methods for long-term stability. His expertise and detailed explanations gave me confidence in my purchasing decision. I highly recommend Patrick for anyone needing a skilled structural engineer for home evaluations or construction guidance.
