Verified record
Diaz Construction Co Inc is based in Avon, Massachusetts, with a Google rating of 3.2 out of 5 from 29 ratings. Every review retrievable here concerns the company's truck drivers on public roads rather than the construction work itself: five people writing between 2023 and 2025 describe trucks cutting across lanes without signaling, running a driver off the road, and, in a 2025 review, drifting into oncoming traffic to take corners. More than one reviewer says calls to the office about it went unanswered. The company also carries a serious regulatory history. OSHA classified a 2013 inspection of Diaz Construction as a fatality/catastrophe inspection and issued four serious citations totaling $16,170 in penalties; the case was closed in 2014. Separately, BuildZoom's Rhode Island profile for the company shows the same commercial contractor license, number 32502, listed as both Active and Verified in one place and Inactive in another on the same page, alongside two additional Rhode Island residential licenses marked Inactive. The one trade signal beyond the general-contracting category itself comes from OSHA's own industry classification of the company as a masonry contractor. Given the driving complaints, the fatality-related OSHA history, and the conflicting licence listings, a homeowner would be right to confirm the company's current Massachusetts registration directly with the state and ask pointed questions about safety practices before hiring.

“Yes, I had the same experience this morning with one of the drivers which I have the plate number and a video. This guy look like he was doing a video call. Going all over the place. He literally almost ran me off the road. Why can't we get a hole of the office?”
Yet another complaint about reckless drivers. Way too fast, needing to hit engine brakes constantly, drifting into opposite lane to make a corner.... despicable. Treating residential areas like highways.
This company’s truck drivers are reckless to those around them! I was driving in the right lane of rt 24. I could see about a half mile or so ahead of me a construction dump truck also in the right lane but it had hazard lights on. After a little bit I decided if the truck was having an issue I’d play it safe and move over to the middle lane. There was still a great deal of open space between myself and the truck when I decided to move over to the middle lane. When I moved to the middle lane the dump truck did the same, ok nothing wrong with that. I moved back to the right lane, the truck did the same. I’m starting to think this is very odd as I’m getting closer to the truck I’m not feeling safe so I move again to the middle lane. This time I’m too close to the truck for him to cut me off but they start to move the tuck middle lane attempting to push me over. At this point I’m panicking because I have NO idea why this driver is acting this way. I’m terrified I’m going to be pushed into the cars in the far left lane because this drive has decided they want to play with the lives of the people around them. I slow down and the driver slides in right in front of me in the middle lane. I again now move to the right lane just praying I’m going to be able to get away from the psychopath driving this huge dump truck. Again he tries to slide back over to the right lane but just like a few moments ago they were too close to me so they couldn’t but again they began to intimidate by moving over just enough to scare me that they were going to push me off the road. Finally I was able to reach my exit and get away from this person but they should NOT be driving trucks like that. I don’t know why they decided they wanted to intimidate and endanger my life as well as those around us with this “game” but it was absolutely reckless.

Your drivers are reckless and endanger all motorists!
I also am leaving a bad review due to one of their drivers. The driver came flying up the left lane on RT140 and at the last second cut into the right lane cutting me off to take the exit. Then on RT24 proceeded to change lanes not using turn signals. I emailed the company and of course got no response. Hopefully state police or DOT will be made aware of the issues with this company and action will be taken.
