"Second time hiring Action windows and I wish I could hire them for everything. Where it counts us if you have an issue and how it's handle. Small. Problem was handled asap and they even sent manufacturer out right away to repair it. Said they would do it themselves if necessary. Wonderful superb company to work with. You won't be sorry. I look forward to siding next with Action windows and siding."

"Acquired new commercial insurance that required me to perform recommended upgrades to a rarely used storage shed. Jack was responsive to my request and performed the required work efficiently and above and beyond the minimum required by the insurance without breaking the bank. As a small business owner I really appreciate working with companies that don’t waste my time or money to complete the endless list of requirements to run a successful company. Thanks again for a job well done !"

"Dylan did a fabulous job managing our window order, ensuring we had the right measurements and showing us how to use the windows and door. Diego, the crew leader, was polite and worked with us to move everything we needed away from the old windows. We are happy with our new windows! Home genius also installed our new roof and gutters. Each job was completed in one day including cleanup. They were careful to minimize damage to flower beds. Crews were on time, and minimized disturbance. Home Genius has done a good job choosing their contractors and job site managers, clearly focused on customer service and provides quality workmanship."
