Knock Knock Home Inspections is a Provincetown, Massachusetts home inspection business for property purchases. The company describes itself as owner-operated by Ross Zachs, who brings property management, investment, and renovation experience to the work. The Massachusetts registry lists an active home inspector licence, 1137-HI-1, under Ross J Zachs, and the company says it is an ASHI member. Two Google reviews from April 2025 describe a focused, thorough experience. One homeowner said Ross was extremely thorough, made himself available for follow-up conversations, and explained details clearly after the inspection. Another reviewer described the service as fast, professional, and thorough, and said they would use the company again. The Google profile shows a five-star rating from two ratings. The clearest fit is for homeowners and buyers who want a detailed inspection during a property purchase, especially when they value time for questions after the visit. Ross's owner-operated role and the registry listing give the business a direct professional identity, while the reviews point to careful explanations and responsive follow-through. Before booking, ask what the inspection includes for the property type and how follow-up questions are handled after the report; the available customer comments specifically praise that access to explanations. The company website self-reports Massachusetts License #1137, while the registry provides the full active number and holder.

Ross at Knock Knock did an extremely thorough job on my home inspection. I was out-of-state during the inspection so I wanted to dig into some of the details that required extra time and further explanations. He made himself available to me for a number of conversations that helped sort out some issues which I wanted to understand better. I recommend Knock Knock to future home buyers.
Fast, professional, and thorough. Would (and will!) use again.
