"I recently had my attic insulated by this company and had a great experience from start to finish. The entire process, from the initial energy audit to customer service and the final installation, was smooth, professional, and well organized. The crew was incredibly kind, hardworking, and patient with all of my questions while they were on site. You can really tell this is a business with a family feel — everyone treated us with care and respect, and it made the whole experience much more comfortable. I would recommend."

"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."
