However, after only about 15 minutes of inspecting the entire house, he concluded there was nothing to worry about. About a month later, a contractor had to remove all of the floors due to significant sagging and install new joists because of damaged joists in the basement. In addition, there was water entering the basement due to improper grading -- something that was also never mentioned in the inspection. As a new homeowner, I relied on this inspection to identify major issues. This is my personal experience, others may have had a better one.

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.

Louis has a structural engineering background was very meticulous about understanding the structure (and slope grounds) and home systems. He was professional, caring and took the time to educate me on how these systems work, what to look for and made sure I had an understanding of it. We went at my pace which I appreciated. I felt assured that he was a man of integrity and honesty. He turned my 600 page report around in 24 hours (at my request) even though I agreed to 3 days. He also gave me a few tips for the town and has made himself available for follow up questions and offered to go back to the home to gather updates. I highly recommend Louis for any home inspection.

Joseph, you were a lifesaver for us!!!!!!!!!!!!!!!!! We were…read moreunder contract on a house, and it felt like the sellers were trying to hide a problem -- one basement wall was literally blocked off with boxes stacked almost to the ceiling. He moved everything , checked carefully, and found structural cracking that could have easily been missed. He even looked behind the refrigerator -- who does that? What really blew me away was how detail-oriented he was. He wasn't rushing, and he wasn't doing the bare minimum. He was genuinely trying to protect us from making a very expensive mistake. And on top of that, he explained everything in plain English. He used simple examples to explain how the foundation and framing work -- the kind of explanation you could tell to a kid and they'd get it. That clarity made it easy for us to understand what we were dealing with and make a decision. I'm honestly so grateful. Buying a house is a huge commitment, and Joseph treated it like it mattered. If you're looking for a structural engineer who is careful, honest, and SUPER detail-oriented, I can't recommend Joseph enough.
