“Rovegno’s [K2 Weatherization] has performed multiple weatherization services on my home ranging from attic insulation and airsealing to installing new replacement windows. I am actually planning on having them replace a few more of my windows in the near future. Their work has always been high quality and their employees have always been polite and professional. When I had a issue with one of the windows they promptly took care of the problem. I would recommend them to anyone seeking to make their home more comfortable and energy efficient!”
