William C Diamond Plumbing and Heating

Extremely disappointing. After a careful search, verifying their licensing, better business bureau rating, and reviews, we decided to go with Diamond. Do not recommend Diamond Plumbing. Our work was subbed out 100% to another company. The subcontractor was not local and started extremely late each day which delayed our project and inspection. They kept prioritizing other jobs over ours. The subcontractor damaged our water line and then knocked on our door trying to convince us to replace our water line while the trench was open, failing to disclose the damage that occurred. After a call to the town to fix the leak and our own inspection, we declined the work. Diamond was there to pick up the checks, and that was it. Do not recommend Diamond Plumbing.

Diamond plumbing did an excellent job hooking up the water and ice machine for our brand new refrigerator. The plumber that showed up was very professional, courteous, and efficient. They are very transparent and give you upfront estimates right there on the spot. HIGHLY RECOMMEND A++++

I have used Diamond Plumbing now for 3 separate occasions. I was recommended to them by a friend that works with the company renovating homes. They have been very prompt for each issue that I have had. We had yo have 2 separate pipes fixed, and a faucet (all of them probably over 60 years old). On the one pipe issue, the technician that we had even offered us 2 options to fix it, understanding that we would need to do the financially responsible thing during COVID. I really appreciated him giving us a less expensive option that still fixed the problem! They are excellent about getting back to you right away, and always show up on time, if not early. It is nice to have a plumbing company that you can trust these days.
