Mark was right on time, and his estimate of time and price for the job was perfect. Very professional, engaging, knowledgeable, and responsive. I finally found the plumber I've been looking for for all our household plumbing needs!
Coleman's Plumbing Inc - K P.
Excellent work under the kitchen sink. He also commented regarding possible future plumbing issues we may experience in our utility room; I appreciate his forthright comments in this regard. It's apparent that he cares about the quality of his plumbing work. As a master plumber, he knows...
- Robin C.
Dave is the best and most honest plumber around. He is great.
- William K.
They did a whole house plumbing inspection and a water heater flush.
Shipley Plumbing Heating & Air - Lane H.
We were very impressed with the customer service, punctuality and results. The plumber, Joe Lyons is a very nice man, helpful and would highly recommend asking for him if you want an experienced plumber.
Mallick Plumbing & Heating - Franklin I.

"I highly recommend DES! I arranged a consultation after a home inspection report indicated that there was moisture in our basement walls. I was worried that costly mitigation efforts would be required. A friend who had previously used DES for a basement water problem highly recommend them, telling us that they were an honest company that only does what is necessary to solve a problem. Happily, Mark Fine from DES inspected both our basement and our exterior grounds and reported that there was no indication of cracks in the foundation or water intrusion, and that no work needed to be done. It is so refreshing to have a company that doesn't try to sell expensive services when they are not necessary!"

"Don’t use the plumbing! Called to have Kohler toilet tank plunger repaired. Whole installation is $20. Labor is an hour at $80 so the price is $150, at most. No, they charged $450–BS! These guys are a scam. No prices and I told them to have the repair person call me before arriving. No call, no prices. And, then the repair person has the stones to tell me that everyone overcharges!! Let’s start with not using Beacon!!!"

"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."
