"When we realized our water heater was leaking, Aldo's was fast both to respond to the inquiry and to get us a replacement; within 36 hours, we were back to having hot water with a new tankless setup. Pricing was within the range we expected and the team was very communicative; I'd hire Aldo's plumbing again!"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"I spoke to the company owner Lou Schede on Sunday and we scheduled one of his service technicians to meet me on Monday. I informed him I would like to receive at least one hour notification prior to the person arriving for the appointment. The next day I received a text from the service technician named Kelroy. He later called me an hour in advance of arriving for the service call as Lou had committed to do. Kelroy and his helper went on to diagnose and repair the furnace issue in timely manner. I appreciate, he was making efforts to repair the furnace on this first service visit rather than replace unneeded parts or require an additional (more costly) follow up service visit."

"Finding a reliable contractor is tough these days, but I got lucky hiring Chris. He and his son arrived on time, replaced my electric hot water tank, fixed a leaking guest bathroom sink, and cleaned up afterwards. Chris is a true professional with a great attitude excellent work at a fair price. I highly recommend him."
