I would recommend Summit Environmental Solutions. I hired them for blown in insulation. I think they did quality work for a reasonable price. I would have given them higher ratings if they provided better customer service. The estimate visit was rushed, and I personally had to be very proactive in getting all of my questions answered, arranging to have all the work done and getting the work scheduled at a later time. This company should have made more effort and more time for questions and concerns or followup via phone to address them. Their workers were proficient, professional and neat when they came to my house. Rebecca and other representatives on the phone were very helpful.
