"We used T. H. Malloy & Sons back in the eighties when we lived in Cumberland RI. They haven’t changed in forty years!!! Still reliable, reasonable, and a pleasure to do business with!"

Maurice Cotton

"Just purchased our home and got a friendly note from Hank that they had been servicing our home for over 30 years with the past owners."

Richard Moore

"T.H. Malloy & Sons have been a joy to work with and they truly go above and beyond to ensure communication, professionalism, and top quality work. My basement was spotless after the install of a new oil tank!!"

Sarah White

"Without Hank's diligence, concern, and excellent customer service, we risked our new house having burst pipes and extensive water damage. He saved us from stress, unexpected costs, and damage to our new house. What a way to start service with a new company!"

Chrisanthi Zotos

"I recently switched to TH Malloy and could not be happier with their service. They have been welcoming, responsive, and reliable. Most importantly, they are incredibly kind."

Lisa Marceau

"My childcare center unexpectedly ran out of oil on a very cold morning. I called T.H. Malloy to let them know and see if we could get a delivery. As soon as they found out there were children on site, they rerouted their delivery scheduled to make a delivery within an hour."

Rebecca Madden

"We have been with Malloy since we purchased the house 23 years ago Never have had a single problem with them, a couple time we had boiler problems and they came right out. The personal in the office and the techs that come to our home have always been very polite and help! Would never think for a second of changing companies!"
