"I am glad I hired the Level engineering and Inspection. My property was damaged substantially due to a deep freeze. The insurance claim adjuster was not helpful and was trying to take an advantage of my ignorance. I do not know anything about architecture. Without their help, I would have never found the actual replacement cost would be over $80,000. I am planning to hire Bryan Conkle again to make sure the work is done correctly and precisely between the replacement of the subfloor and the replacement of the engineered wood floor. Thank you, Bryan, for your great work. You are awesome!"

"We have been working with Sam on our home project to take down a load bearing wall and we are pleased with his work. I liked that he enjoyed small projects and the city engineer approved the plans the first time they were submitted. He also has come by to inspect the work our contractor has performed and advised the corrections that needed to be made so our home would be structurally sound. I highly recommend."

"The person assigned to our project, a small room addition did not capture what we were looking for. She had errors in her drawings. If she would have reviewed her design drawing she would have seen that some of the layout did not make sense (i.e. not enough room for a certain cabinet, the counter top was not right) Her dimensions were off."

"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"Raj, is a stand-up guy full of integrity. We needed Structural Engineering Design and Calculation services for a retaining wall in our backyard- the wall is neighbor adjacent and retaining a slop, and would exceed 75LF in length and 4FT height. It needed to be designed thoughtfully; And we needed it to be prepared and presented to the City for a Building Permit, so it also had to adhere to our city's unique municipal codes and ordinances. And we needed it done ASAP. Raj, took the challenge and delivered! Raj, came over immediately, he worked over the weekend for us, and delivered all the necessary designs, calculations and drawings, such that it can go to the City by Monday morning. All while putting up with our countless questions, emails, and phone calls. And of course the Engineers at the City Planning & Building Department granted the permit without hassle. His patience, professionalism, and calm demeanor is why we will call Raj again for all of our Engineering needs in the future."
