Envirotech Electrical Services Inc and Insulation

I called Envirotech and Mark came to visit my home. I told him about the cold room above the garage and other rooms being cold. He explained to me the reason for the problem. He provided me with a reasonable estimate.
He suggested to increase the Attic insulation to R50 and insulate the external wall and celing of the garage. We scheduled a date for the work and his staff showed up on time.
They worked for 7 hours and after they finished their work, they cleaned the area that they worked on. The next day my cold room was gone and the temperature upstairs was warmer by 1.5 degree.
Job well done and I am very satisfied.
