"Very professional. Arrived on time to install a garage door opener. I had a chicken coop that needed to be assembled and he agreed when this wasn’t what he was hired for. Not only that but he replaced a rotted broken door on another chicken coop! I would definitely recommend Better Dayz!"

"Would highly recommend par holdings to anyone that needs electrical work done. They handled everything from the permit to calling the town inspector. Dennis sr and Dennis Jr were both wonderful to deal with. Had the work done on time, on budget, and no stress. I highly recommend their company for anything that you might need."
