Our Team & Mission


Green Homeowners United was started for a simple reason: to make it easy for people to do one of the most important steps to fight climate change and save money in the process. Join us in helping cut carbon emissions at home.

Green Homeowners United exists to make it easier for homeowners and homebuyers to improve their property with renewable energy, energy-efficiency retrofits and water saving opportunities; and we help people find fair financing to afford the carbon-cutting upgrades that normally would be out of reach. Click here to see if our green home upgrade program could be right for you. You can learn more here about how we seek to ensure all homes can be upgraded, and check out our latest happenings and success stories here.

We're also a proud union shop, providing health benefits, training programs for workers to expand their skills, and a pension for when they retire.
