We initially contacted Evergreen through Efficiency Maine for an energy audit, which was conducted promptly and professionally by Justin McEdward, one of their Energy Advisors who is BPI-certified. After a thorough inspection of our newly purchased home, Justin explained in great detail what we needed and did not need. It was agreed that Evergreen would remove all of the existing attic insulation, which was not adequate, and replace it with blown in cellulose, to a rating of R-60. This also involved removing defunct heating ducts, sealing the chimney chase with sheet metal and fire-rated caulk, and sealing all the electrical and plumbing penetrations and other voids. In addition, AccuVents were installed around the attic perimeter, a bathroom vent was extended for exterior exhaust and a tent hatch cover was installed over a drop down staircase. All of this work was conducted under very difficult conditions in that, while the attic is extensive, the overhead is very low and provides little space within which to work. Nevertheless, the crew, led by David Holmes, got the job done cheerfully, on time, within budget and in a very workmanlike manner. We were consulted at the beginning and end of every workday and whenever any question arose. Otherwise, the work was not at all intrusive. The entire operation was successful from every point of view and a comparison of the blower door test prior to the work and after completion indicated more than a 30% reduction in outside air loss. In addition, the cost of the project qualified for an Efficiency Maine rebate, which Evergreen prepared and submitted on our behalf. Over the course of forty-plus years of home ownership and a number of significant repairs and renovations, our considered opinion is that Evergreen ranks right up at the top and they have our highest recommendation.
