Finding a contractor can be challenging, and EnergySmart is here to help! Below, find lists of contractors who work in Boulder County, broken down by category of work. The listed contractors have demonstrated interest in helping residents complete energy-efficient projects and apply for funding from utility rebate programs and EnergySmart incentives. Each contractor has completed at least one project with EnergySmart.
Residents may work with any vendor or contractor and are not limited to these lists. However, please note that some utility rebates have contractor requirements and EnergySmart does align with the utility’s contractor requirements to access our rebates. For example, if Xcel is the rebate-providing utility, the contractor will need to be registered on the appropriate Xcel Energy trade partner list for some projects. If the City of Longmont is the utility, the contractor needs to be registered as an Efficiency Works Service Provider for most projects. The lists provided by EnergySmart offer columns to show which contractors are registered in the appropriate lists.
EnergySmart does not advocate for or promote specific contractors and makes no representations or warranties regarding the quality of service or proof of insurance for any contractors on the list.
