I received quotes from a couple of companies, and while these guys weren't the cheapest, they were definitely the most knowledgeable and took the time to clearly explain how the repairs would be done. They completed the job in just two days and repaired two addional piers, and everything went smoothly. I do have a slight squeeze in one area of the floor in my raised home, and I'm currently waiting for them to come back and take a look at it. I know pier repair is not much complicated but their crew was professional and their price was reasonable. I would highly recommend these folks.

I am the president of my HOA and was frantically looking for a structural engineer about 5 months…read moreago to review our blueprints for a homeowner's project. I looked through yelp and even left numerous msgs for various engineers. All of which were either uninterested or charged ridiculous fees. Arsen was recommended to me by a friend and he was perfect for the job. His expertise and knowledge helped us make the very important decision to not remove a structural wall. I recently just hired him again for another project which was in the works since October of last year. After being totally taken advantage of by another engineer, Arsen came by and offered more advise with patience, a detailed explanation regarding the integrity of our building and leveling of another homeowners floors and offered a great report to have on file. He is honest, sincere and above all has a great personality. I would recommend him over and over again!

A few hiccups along the way with the final permit but Sam acknowledged the mistake on his end and said he would sign off the edits in the revision phase of construction. I will give an updated review once that time comes. Quality: quality of work was good. Efficient in communication and dealing with a difficult city in a permitting process. Took about 6 months for the permits and the city kicked back for corrections 2x which is pretty standard. Value: felt his pricing was fair and reasonable Customer service: always responds to phone calls. Even after our final payment when we had questions or needed assistance. So not a "take your money" and we are done type of guy Overall impression: would use him in the future for any architectural or structural engineering jobs

What more is there to say? There's too much money, too much unknown when you're renovating your house, and trust is the most valuable asset you can have in a contractor. Trust that they are working doggedly for you. Trust that the work is great. Trust you are getting way more than your money's worth. Well, we trust Art and Extreme Home Addition intrinsically. You should too.

I found Sam through Yelp. At first, we were both not sure whether we will work together because he…read morelives more than 20 miles away from where I live, and I'm the type of person who is always skeptical about what I read on the internet. But now I'm very happy that Sam decided to take on the job and develop the structural calculations and drawings for removing a load bearing and shear wall at my Condo. The Project started in September 2025 with initial submittal of permit application package to the City. It went into construction about four (4) weeks ago and was successfully completed today (5/8). During the process, we developed trust for each other. I contacted Sam numerous times for questions, problems and consultations and he was always responsive. He and my architect friend worked together to develop the initial design but had to modify it to overcome a major obstacle that came up during the construction. He came over for construction observations and gave instructions to the contractor how to strap the beams together for maintaining structural integrity of loading and shearing. His fees were much lower than another builder whom I also got a bid from, and his approach to things was much simpler and yet conservative to that from the other firm. I told Sam, whether it is good or bad, I don't usually do reviews for others. But for him, I will do one. I'm thankful to have a great team of Sam (the engineer), my architect friend, and excellent construction crew to help me complete this project.

He never disclosed in that conversation that in order for him for him to come out and see my job and meet me and look at my property, that there would be a $350.00 "site-ck-fee" before I even met the guy. He sent an e-mail telling me that I had to pay that on Thursday, Jan 22, 2026. I replied and asked for clarification. then he replied (via e-mail) that i only had to pay 1/2 of that fee to "Confirm and hold the appointment". If you are ok with that, I guess "go-for-it".
