We needed a structural engineering evaluation and had recommendations for two companies. We planned…read moreto go with the recommendation from our general contractor, thinking that this would be the easiest to coordinate with the rest of our project. Scheduling was not a smooth process, however, and more than a week after they were contacted, we still had not been given an appointment. We contacted Nick at Colonna Consulting and easily scheduled a date for the assessment. We were also finally given a date by the first company, which was one day earlier than Nick's schedule. Their contract stated that reports were usually ready in 2-3 days, but that this was not guaranteed. Nick told us we could have a report the same day and that he would work on the architectural drawing over the weekend (appointment was on a Friday afternoon) if we needed one. We are very happy that we decided to go with Colonna Consulting. Nick arrived on time for our appointment. He was very professional and spent more time than we expected explaining what he found and the appropriate remedy. He was extremely patient and answered all of our questions. We did need an architectural drawing, which was completed over the weekend and sent by email on Monday. He sent the original directly to our contractor for submission with the permit application. I recommend Colonna Consulting without any reservation.

Tettonis Engineering has far exceeded my expectations. Vasili, the Principal Engineer, responded…read moreswiftly and scheduled a preliminary chat for the next day. I expressed my concerns, and he was very thorough in providing the history of the site. Within the same week, he conducted an on-site investigation and implemented a wall crack monitoring system. He meticulously combed through each room, outer, ground, and aerial spaces, pinpointing the potential sources of water infiltrations and assessing the potential impacts of the trains nearby. Vasili has an astute sixth sense for identifying issues.

I found Jim through Yelp while super stressed about some aspects of my home. He was responsive and…read morewas able to come out quickly to do an inspection. Jim was extremely kind and knowledgeable. He took his time reviewing every single thing that I had on my list. He never once scoffed or brushed off even the tiniest of drywall cracks or nail pops that I was nervous about. I shared with him I was a first time home owner and he even offered some tips on how to repair some of the unsightly cracks or poor workmanship that I was asking him to review. He helped me understand some of the specifics of how the home was built, clearly outlined what was normal, and things I can watch out for in the future that would elicit more concern. I found his price to be extremely fair for his expertise, and I appreciated that he had a separate, optional price for a written report, so for those like myself that didn't end up needing to do any remediations, I didn't end up paying for that additional service. I highly recommend Jim to help stomp out things that are making you toss and turn at night like me, and to be used during the inspection process for a new home. Thank you, Jim!
