I have a tri plex that needs 3 heaters replaced. AB/JDD came out a few months ago to inspect for a quote. I got a very vague bid and requested more detail. After 2 phone calls I got an email saying the job was too big. They are under new ownership. If you have a larger job, don't waste your time.

An excellent company to work with. Dave and his crew did a great job installing in a new water heater in my home. They were prompt and professional. I would definitely recommend Dave to my friends and family

Late one evening we had slow bathtub drain which turned into the toilets receding and the bathtub completely clogged. We managed to last until the morning and had AB/JDD come out to take a look at the problem. They arrived and decided what was the best course of action. One tech started to snake through the sink as they said that was best way since our toilets in the 2 bathrooms were back to back. The other tech was assessing the exterior of the house to locate the cleanout. Unfortunately, our house did not have a cleanout. The pipes were snaked but they were unable to reach the clog and I was provided with a quote for their team to dig and create a cleanout.

We thought the quote was an outrageous amount of money and reached out for a few others. Our concerns were validated. The company that we hired to do the work had sonar equipment to locate the pipes and provide the quote. They placed the cleanout in an inconspicuous location (not in the middle of the front yard) and charged us 1/4 of what AB/JDD quoted.

Buyer beware, it's always in your best interest to get multiple quotes before getting any work done.

I can't say enough wonderful things about Dave @ AB/JDD. I called Sunday about back up problems (water backed up in to tub, toilets didn't flush). Dave was here within 1/2 Hour. He snaked the drains, cleared up the problem promptly and was totally professional. Yes, I paid extra for work on a Sunday. Big deal. The problem was resolved & toilets flushed, laundry done. Dave was a game changer!

Great Experience with AB/JDD Plumbing! Mike came out to our house on Tuesday, May 1 to clear a slow running drain. Did a great job. Later I called him back on Monday, May 7 to replace a fifty year-old section of 2"" cast-iron drain line with new 2"" ABS drain line; outstanding work. Mike is a courteous, knowledgeable professional who answered all my questions about what he was doing and even explained what tools he was using when I asked. From the beginning, Leslie the office manager did a great job of listening on the phone to me describe the plumbing problems we were having and she followed through with scheduling and emails to make sure that our plumbing jobs were completed successfully. Best Work at a fair price. Thanks AB/JDD Plumbing!

I used them once to clear my washing machine drain. Not that expensive and they did a good job. I called them recently and received a reasonable quote to replace a water heater. The owner was very helpful, although family members ended up doing the work, I will use them next project that we cannot accomplish on our own.

I've used AB/JDD twice and been very satisfied both times. These weren't big jobs - once to replace my kitchen faucet and once to fix a leak under the kitchen sink. Both times the work was done professionally, the plumber was pleasant and the charge was reasonable. I would use them again.

Professional and fast service. They came to my house and fixed the leaking faucet. My shower faucet broke and water was shooting out of the faucet. They fixed it in no time. I would recommend them highly. They are honest and professional. Did not charge outrages prices like other plumbers might have. Call them first. I am so glad I did.
