I had a great experience with Marc! He showed up right on time, was extremely thorough, and took his time going through everything with me. He was patient with all my questions and did a great job explaining what he found, what actually needed attention, and what was simply cosmetic.
I really appreciated his knowledge and expertise, but even more so his willingness to take the time to make sure I understood everything. I never felt rushed, and he made the entire process easy.
Definitely a 5-star experience. If I ever need another inspection, Marc will be my first call. I wouldn't hesitate to recommend him to anyone looking for a home inspector.
Thanks again, Marc!

Marc is a breath of fresh air to the home inspector world! I'm a local real estate agent, and have recommended Marc to multiple clients now. He's fantastic for existing construction, new construction, and even a home that's under construction! My clients are overly happy with Marc and his entire process, beginning to end. Most importantly he's thorough, realistic, he supplies a user-friendly reporting system, and his inspection reports are the easiest I have ever read from a home inspector. The cherry on top is his communication; he likes to have all parties involved, sends reminder text messages, and follow-up as well. Ensuring you're happy with your inspection days after you leave the property is rare to find from an inspector. Don't hesitate to book mark for your inspection needs!

Had a great experience with our home inspection! Marc was incredibly nice, responsive, and very thorough throughout the entire process. He even uses a drone to get a good look at the roof and other areas that are difficult to see, which I thought was awesome and gave me some extra peace of mind. We received the report the same day, and it was detailed but still very easy to read and understand. His pricing was also extremely competitive to other inspectors I called. for how thorough the inspection was. I would absolutely recommend him to anyone needing a home inspection.
