A 2022 customer said the company did a complete replacement of their outdoor sewer pipes and re-routed the indoor piping to the new line. A 2022 customer who hired them to set a tub and reroute a drain line said the mechanic, Sean, cleaned the job site and removed all the garbage before he left. A 2022 customer who needed a furnace replaced said Bill squeezed them in the day they called and everyone stayed late so they would not be without heat overnight.

A recent customer said they were charged $1500 to remove a leak-prevention device from a washing machine, a job they said took about 2 hours.

A 2024 customer said they were charged $564 for two leaking faucets that were not fixed and for redoing a drain job from six months earlier. A 2024 customer with a dripping shower said the technician proposed replacing all three cartridges or the whole shower body, and that a new valve gasket alone fixed it. A 2022 customer who had two toilets replaced said they were told $187 an hour plus a $30 disposal fee and were charged about $650, with no line items for parts.

These guys knew what they were doing. They installed a new, low profile, wall hanging combination hot water heater and central boiler for our HW system. Bills for energy were significantly reduced, we gained a lot of room in our utility area and with their ongoing PM we have enjoyed problem free, reliable heating at about half the cost of our prior heating systems.
