Keystone Home Inspections is an Upton-based practice built around a small roster of named inspectors — Sue Reider anchors much of the history, with Chad and Keith turning up in more recent reviews — and it's licensed in both Massachusetts and Connecticut, adding radon, water, and mold testing alongside standard home inspections across central Massachusetts and northeast Connecticut. The strongest, most repeated thread across five years of reviews is how inspectors walk buyers through what they're finding. Multiple first-time homebuyers describe an inspector explaining not just what needed fixing right away but what could wait, what was DIY-able, and what needed a specialist — genuinely useful triage for someone new to owning a house, not just a checklist read-off. One reviewer recalled Sue running fifteen minutes ahead of schedule and using the extra time to walk through the inspection contract itself before getting started. Two reviews break that pattern, and they're worth taking seriously. A 2024 review described structural issues that went undetected at inspection and cost tens of thousands of dollars to address over the following two years — the reviewer called the inspectors good, sincere people but said they couldn't recommend the company after that experience. A 2022 review described a similar arc: an active termite infestation and roughly $20,000 in damage that surfaced only after closing. A missed inspection is the one failure mode that actually matters in this business, so both are worth weighing against the otherwise consistent praise. The company carries an A+ Better Business Bureau accreditation and has been in business for a decade, with no complaints listed on that page. Worth a call for a straightforward MA or CT inspection where you want someone to actually explain the house to you — just go in aware that no inspector catches everything every time, and ask pointed questions about anything structural or pest-related before you close.
“I always recommend my go to- Keystone Home Inspections in Upton MA.”
As a first time homebuyer with my husband, Sue did an incredible job addressing minor repairs and conducted a thorough inspection. Would definitely hire again!
We had Keith help do the inspection with the house we made an offer on and he couldn't have been nicer. Very thorough. Took tons of pictures. Reasonable price. Explained EVERYTHING in a great and respectful manner so that we knew what we were buying/getting ourselves into. Very good at saying what he knew would need fixing right away or what would need professional help versus what I could fix in the early stages of owning. Audi who helped coordinate the whole inspection was also helpful and nice. I would recommend them to anyone in the area buying a house.
I had an excellent experience with Keystone Home Inspection. My inspector, Chad, was extremely professional, thorough, and knowledgeable. He took the time to explain everything clearly, answered all of my questions, and made sure I understood the condition of the home from top to bottom. The report was detailed, easy to read, and delivered promptly. Chad’s attention to detail and professionalism gave me a lot of confidence moving forward. I highly recommend Keystone Home Inspection and especially Chad to anyone needing a reliable home inspector.
My inspector Chad was extremely thorough and showed/explained everything to me that needed to be addressed. I’m very satisfied with the quality of service Keystone provided.
I am a city girl hoping to buy a log cabin - think that says it all! I didn’t know whether I’d understand anything during the inspection. We were very lucky to have Sue as our inspector! Not only was she extremely thorough and knowledgeable, she explained everything in a way I could understand, including the purpose of her cool gadgets. This clarified our options - such as when we absolutely should bring in experts and when we may be able to DIY. Inspections are tricky because you want to know everything about what you are getting into but you’re already serious about the purchase. Sue made a stressful situation a wonderful, educational day that helped us make key decisions about the property and prioritize what we need to focus on. I would highly recommend Keystone Home Inspections!
