I hired Dan for cutting into and excavating multiple access holes in the concrete slab in a new construction High-end Apt building in Cambridge. As a contractor myself I have over the past 40 yrs a significant list of "The good the Bad and the just plain useless and dangerous.. Our usual sub wasn't available for this job .This was a time sensitive and needed to be done to meet the city inspectors and the Utility companies that had misdirected the gas service to the building. I've known Dan socially for 10+ yrs and consider him a friend.I called Dan on a Whim knowing he could perform what was required but not his schedule..b Dan dropped what he was doing and was onsite later that morning.

Not cheap, but worth every dollar spent ..saved weeks of delay . read more
