"By Andrew v. Engineer Dave Schofield of Capstone displayed professionalism by turning a flawed design for our Sudbury septic system into one highly adaptive and functional. He was purposeful about doing the right thing even when not winning installation contract, execution of which he in in fact supervised. In a business which includes its share of uneven performers, Schofieldâs competence is a stand-out."

"After a phone call with a representative that called me and discussion of the work I was looking for, and mentioning a number of times the work involved a site visit was scheduled. When the service person came to do an onsite evaluation, I was told: 'we don't do oil tank removals and installs.' Representative was obviously not trained for what I had requested during our phone conversation and that Nicholson Heating, Cooling, Plumbing and Electrical didn't do this service or wasn't informed of it during training."
