As part of getting all of our HVAC equipment replaced I wanted to add significant insulation to our attic space and get it air sealed. I had already found McHale’s but they were also mentioned by one of the HVAC contractors as being one of their subcontractors. McHale’s gave me a very competitive price and their work was excellent. Spent hours air sealing the top attic space in our split level home in San Ramon, then added insulation up to about R55 I think. Kind and courteous crew of two came and did all of this work, taking most of a day. They did a great job, laying down tarps and cleaning up afterward. I wouldn’t hesitate to recommend them and would certainly use them again. Our house is now incredibly comfortable.
