We took full advantage of the rebate program and had @ $4000 worth of insulation done to our old house. Our cost was @ $1500 after the rebates. It was a 1400 square foot home with a full basement unfinished. Needed 6 inches of blown in insulation in the attic, the walls had zero which we also had blown in. Air sealed the attic and the knee wall (basement/foundation). The recommendation and service...

Description of Work
Complete energy audit. Took 3 hours. Checked negative pressure in home with blower door test; inspected walls with heat gun. They wrote up an average cost to add insulation to the attic, walls and air sealing of our attic and basement. They work in conjunction with Columbia Gas with a rebate program and still do. We were given a programmable thermostat and water saving shower head. Fabulous!

Description of Work
CONSERVATION SERVICES GROUP conducted several energy audits of my home (built 1920) over the years. 2003, 2008 and 2011. During the audits, they installed energy and water saving devices as part of the Mass Saves initiative sponsored by Massachusetts' gas and electric utilities and energy efficiency service providers. In 2011 the air sealing and insulation work was done by McEachern Inc and certified as complete by CSG. (Approximate cost to me after conservation rebates, etc. for the CSG air sealing and insulation project was about $2000.) Unfortunately, an inadequate air sealing and insulation job and an inappropriate certificate of inspection has resulted in gutter damage that is costing me a lot more. See Current Problem below.
