"I'm a General Contractor (Jon Beer Contracting is my company) and recently worked with Corey and his team from Prestige Energy Solutions. We are doing a combination of a gut renovation and a new build on my own personal home that had a lot of tricky details and moving parts. From start to finish his team was professional, attentive, clean and skilled. I wouldn't hesitate to hire him for our future insulation needs."
