"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"I contacted Home Advisor late one night after my water heater gave out. Cliff contacted me the very next morning, telling me he'd be at my home within a few hours. He arrived, inspected my water heater, diagnosed the problem as the unit needed to be replaced, and replaced the unit. Now, My water is hotter than it's ever been in the time I've lived here and the pressure is greater than I've ever seen."

"Company responded fast to an emergency. My heat pump/hvac unit failed in 90deg temperatures. Technician came and diagnosed that system is 20 years old and needed replacement. Sales team was excellent and helped pick the right system for my budget. New system was in stain less than a week. Will hire this company again"

"I cannot recommend Mark more! We called him for a dishwasher installation and pipe repair. He quoted us reasonably - and was generous with his work and time when what we thought was a simple job turned out to be much more complicated. He was absolutely a pleasure to work with - communicative about the issue and his solution, flexible with scheduling, and just an all-around nice guy. We will not be hesitating to call him in the future - our go-to-guy for all plumbing needs."

"Great. They called to make appointment. Called to let me know they would be there in 15 minutes, Were on time, professional, efficient. Due to house and plumbing being 50+ years old, they did have to find a part at the supply store but came right back and finished the job. They advised us to get the lower shut off valve fixed in the future and sent us an estimate. Very pleased and would recommend them to my friends.$199"

"Had Badaracco come in to do a dishwasher install which necessitated replacing some plumbing under the sink. Realized, after the plumber left, that the dishwasher door was rubbing against the countertop and wouldnâ t automatically open at the end of the wash cycle. Badaracco returned the next day and found one side of the dishwasher, where it attaches to the cabinet, had come loose. It was a 5 minute repair at no charge. Dishwasher is working well now."
