    HomeStart Inspections did an inspection for my purchase of a new home.  Alan was incredibly thorough and did a great job walking me through his findings.  He was excellent at meeting my level of knowledge without over or under explaining the technical aspects of the report.  The office staff was also extremely helpful and responsive during scheduling.  I would highly recommend HomeStart Inspections!

    We had a great experience with HomeStart Inspections. Scheduling was easy, and communication was excellent throughout the process. We chose Home Start because they could complete both our home inspection and well testing together.

Our inspector, Matt, was professional, thorough, and personable. He explained everything in a way that was easy to understand, answered all our questions, and never made us feel rushed.

We would definitely recommend HomeStart to anyone looking for a reliable home inspection company!

    Tyler was fantastic. He was super thorough and in-depth as he went through our home and explained his findings. He was very factual, and gave us all the information without underplaying or overstating what things we should keep an eye on or get fixed right away. He was very engaging and it was clear he took pride in his work. Absolutely would work with him again in the future.
