Our Mission
The mission of Dun-Rite Insulation is simple: to provide perfect insulation and weatherization work that enhances comfort and reduces energy consumption.
We go beyond installation by educating our customers and clients on best practices and tips for maintaining an energy-efficient home or business. Our team delivers exceptional customer service from the first consultation to the final inspection, using only the highest quality products and advanced technology in the industry.
At Dun-Rite, we're not satisfied until we've achieved 'perfect work' –
because your comfort and satisfaction are our ultimate priorities.
Mike and his team were on-time, polite, and explained everything. I'm so glad I participated in the Focus on Energy program. My home is more comfortable and my utility bills are lower.
