"Shane Flagg and his partner Doug (knowledgable retiree) are highly professional. Their work is efficient and complete. Erica Dole (in the office) scheduled the date/time quickly. I value the company for their work and their individual friendliness, and will welcome them back to add a 'riser' to the tank. Thanks to you all. Alan Baker"

"No problem whatsoever with recommending Darryl. Price extremely fair. Work was excellent and done under extreme circumstances. I'm sure it is very difficult to install a septic system during the winter, but he did the work very well and came back this spring to finish sitework."

"I came home from work to find all my drains were not draining. I tried some basic troubleshooting, but could not figure out the issue. I called heritage ( which was after hours). Within an hour, the technician Derek arrived, I gave all the information to him, and he started immediately. We narrowed it down to an issue with the septic. 10pm we are outside digging up the septic to get a look. Dereks knowledge and experience quickly identified the issue. The whole time he was friendly and informative. It didnâ t matter the time of night it was, he was determined to fix the issue. He was repairing in a way that would keep the cost down. That rarely happens with contractors. Within 30 minutes, he had the main drain cleared from the house to the septic. Derek even took the effort to double check from the opposite end in my house to make sure it was up to his standards. The whole time he is sharing knowledge and explaining the cause and effects and how the system is designed. When the job was finished, we went over the invoice. I couldnâ t believe the price! For emergency service, and the work that was done, the price was extremely fair. I highly recommend heritage plumbing and heating, and of course Derek."

"Prompt, courteous, professional, communicative. Dave replaced my well pump, pipe and wiring on the same day I called (a Saturday!). All at a very fair price, even though he had to wrestle with the rhododendron bush the well head was hidden by. All he needs is a cape."

"They came out first to find the septic tank and then would have to come back with the pump truck to pump it. After utilizing the camera mechanism to locate the tank, we were advised that pumping wasn't really needed yet. They could easily have led us to believe it needed to be done, but they chose to be honest and save us the added cost. Honesty & integrity, i like that in a service provider!"
