I have a large attic that required vermiculite removal and all new insulation and chose Green Attic as the company to do the job. Vermiculite is an unusual rock based insulation that was used widely for a short period decades ago. Unfortunately, it is now viewed as potentially hazardous and requires special remediation techniques. There is also a national fund that reimburses for some or all of the costs of remediation. Their salesman was excellent, their prices were very competitive and they did they entire job very well. They also took the necessary before, during and after process photos which were critical in receiving my $4900 reimbursement. I would recommended Green Attic whether your job is a standard insulation job or a more complex job requiring guys in white protective suits. They are a well run company with good prices.
