Our Founder & CEO, Chris Kane, spent over 25 years fighting for consumers across Colorado as a nationally recognized advocate and former host of CBS Denver’s Haystack TV and Haystack Radio.

Our team is local, experienced, and deeply committed to excellence. We understand Colorado’s unique weather challenges and plan every job with long-term performance in mind.
