Get matched with top blown in insulation install or upgrade pros in Corona, CA

"I would strongly caution anyone considering this roofing company. We had our roof redone in July 2025, and by February we experienced water damage inside our home. After inspection, the issue appeared to be related to poorly installed flashing around a vent. Instead of taking accountability or even seriously investigating the workmanship, the company quickly dismissed the problem and claimed it was caused by an animal, therefore not covered under their warranty. This was disappointing, especially given how soon the issue occurred after a full roof replacement. A reputable company should stand behind their work and be willing to thoroughly assess potential installation issues rather than deflect responsibility. The lack of accountability and unwillingness to help resolve the damage left us dealing with repairs on our own. Based on our experience, I would recommend looking elsewhere if you want a company that stands by the quality of their work and provides reliable customer service."

"Amazing follow-up by by Darren Kretzer. I had Attic Construction treat my property last year. When I had a recurrence of issues (rodents) this year, I contacted Darren and he came out the same day and took the necessary time to identify and remediate the problem the same day. Excellent Service! I would not hesitate to refer them to all of my friends and family. There work exceeded all expectations."

Miguel worked with my budget and the guys delivered impeccable service. Thanks Miguel, Richard & the handsome young man. I can't recall his name right now"

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."
