Everything leaked so they definitely had their challenges and they were good at helping me only replace the most critical components. The only downside is I found their pricing to be on the (very) high side. I understand good plumbers are never inexpensive but they are pricey. I've worked with several of their techs and they all know their stuff. The work was flawless!

I received a returned call in the afternoon as they stated. They said they could arrive between 8-12 pm the next day. I pleasantly received a call at 8:10 that they would arrive by 8:30. Two very professional men introduced themselves, and discuss what they would do after reviewing the situation. I approved the quote further the repair and when speaking with Anthony I'm I asked if he could review our cooktop as there was slight gas odor from time to time beneath it. Anthony discovered a small leak on the gas connector provided me with a fair quote and proceeded to repair. Within 2 hours all concerns were resolved. I highly recommend Delaware Plumbing Professionals for any plumbing issues.

I'm here in WA state and early this morning my mother in law calls and is just beside herself because there's a leak or something somewhere and water was coming into the basement. My father in law wanted a specific plumber and I couldn't find their number so I actually called these guys and Phil answered, he was helpful and even gave me the number to the other company knowing that they were looking to hire someone else and that showed such character. I thanked him and proceeded to give the parents the number. As the morning progressed I gave my mom in-law Phil's number and he's currently taking great care of them. All this help from a stranger nearly 3,000 miles away. I'm so so thankful that there's still seriously wonderful people out there.

I had the same thing done a couple years ago and that company only charged us $150.00.

It was a slow leak so we scheduled the repair a week in advance and during normal working hours.

TL;DR: they refused service to long-time clients because we had the audacity to ask for a measly…read more$200 off their HVAC bid. Clients of theirs for years, no complaints. When we needed a new HVAC, we got an estimate from Frederick that was $1000+ over the estimate from another long-time, reputable local company. But out of loyalty to Frederick, we politely asked if they would shave $200 off to come *slightly* closer to this other quote. We actually hate haggling, but had read that you're expected to, for new HVAC. Can't hurt, right? They responded. Had they just said, "No, that's not possible due to XYZ," we would have hired them and paid the full price. But instead the rep explained why it wasn't possible, and then, in a polite but insulted tone, *rescinded their bid*, essentially telling us they would not be doing the job either way. All over a request for $200 off a $7000 job. We were stunned. Needless to say, we haven't called them for anything since, and we're the kind of easy-going, non-complaining customers contractors usually like to have. We got our HVAC at the other place and it's running fine, a few years later. Owner, if you're reading this: I get that you're doing well enough that you don't need to accept anyone's attempt to haggle, and can charge a lot more than the competition. Good for you. I'm purposefully not giving you a 1 star because I don't believe in trying to hurt someone's business. But talk to your guys about not reacting in a personal way to long-time customers. The reaction we got was really uncalled for. Maybe the guy was having a bad day, but you have to leave that behind when you're interacting with a customer, especially an established one. He could have just said "No, we can't do that, but let me know if you want to proceed with us." We would have.
