Best in Philadelphia PA

Very responsive (a rarity among contractors from my experience), friendly, professional, and fair rates. They did a great (and fast)  job replacing a toilet for me and based on this experience I would certainly recommend them to others.

Hopkins is the best!
Our Church just used Hopkins Plumbing for the project. They were always there when they said they would. They treated the building as if it was their church. Beautiful work in a workman like manner. Great job, thanks Brian!

Mark and his team are just outstanding. The quality of their work is excellent, they are reliable, honest and have a lot of integrity. They did the plumbing under our kitchen sink, replaced the spigot and put in all new plumbing for the entire house. His team are courteous and professional. Just good business people all around and I highly recommend their services.

I owned my home for several years and had no ceiling light in my living room. My home was over 100 years old, so it was originally gas lighting. Manny placed 6 recessed lights in my living room ceiling and included a dimmer switch! Then he installed baseboard electric heaters in every room including my living room. He did an excellent job and I was very happy.

I worked with Matt on a unique plumbing issue and he was knowledgeable and a pleasure to work with. You can trust in A&P!

Dennis (and his son) were assigned to fix my heater as a part of my home warranty on the 21st, contacted me on the 22nd, and had me back in business on the 23rd. They were on time (calling when 30 min away), wiped their feet, and were quiet (while I was working from home). After checking things out, my unit was fixed in under an hour. Grateful for their punctuality and work.

I'm very torn while writing this review.  I have used this company 4 times, twice for my house, and twice for my rental property.  
Pro's:
*The customer service is fantastic!  Everyone in the office is really nice and incredibly helpful.
*They were always able to get to my house or the rental the day of, which made us and our tenants very happy.
Cons:
*Expensive-We had them replace our water heater.  Now, we were told that this was a more expensive water heater, but we were given a baseline quote on the phone of $1350 (We knew this wasn't exact, so we figured that it would probably cost us around $1500-$1600 total, which we still found to be pretty expensive; however, since we had always had a good experience with this company, we decided to go for it.)  When they came out, they told us that the gas valve wasn't working and needed to be replace, but since the water heater was almost 10 years old, we should probably just replace it, which we agreed with.  The new water heater, with labor cost over $2400, but since we bought their maintenance plan it ended up being $2325.  While we didn't want to pay it, we had no hot water, and did not want to wait, so we went with it.  (If you check online, the water heater costs $1300...so basically we paid $1000 for labor, removal of the old, and installation and delivery of the new.)
*Second con-when the plumber went out to our rental the first time, they had about 3 different issues that needed addressing.  One issue he did not charge us for, as it was to clean out some debris from the inside of the faucet.  Well, the same issue came up about a month later.  We sent the plumber out there, and I asked the company to have him call me to let me know what was the matter with the faucet. (Had the debris become worse?  Since there was more debris is there a bigger problem?)  I never heard from him until he had left the property telling me how much we owed.  We talked about this problem, and he said that if it happened again to call them.  Not exactly ideal as we pay them well over $100 just to go out there, not including any new parts that may be needed.  I really wish, as this is a rental, that he would have done what I asked, and called while he was there so that we could have figured why this kept happening.
So, while the customer service aspect is really great, be prepared to spend!

The leak detection side of their offerings was fine.

However, I made the mistake of hiring them for their plumbing. Their plumber found the most roundabout, expensive way to resolve the issue and turned a $400-$500 fix into a $2500 fix.

Even once it was fixed, it started leaking again a few weeks later. This was supposed to be covered by my warranty, but they wanted more money.I ended up paying another $250 so they would do the fixe the way it should've been done in the first place.

If you use them to find your leak, do not under any circumstances hire them to fix anything.
