I had gone to three other companies for a blown-in insulation project. One came over but did not bother to inspect our attic to determine what or how much was needed. The other two came over made a brief inspection and left me with a quote. When I agreed to one proposal, the company would not return my calls or emails to set the project timing? Never did hear back. Finally, after receiving a referral, I contacted Greenlink. They came over; made a thorough inspection; provided a proposal; we agreed to the price; a time frame was set; the job was completed to my satisfaction. That's the way a project should be handled!
