"recently had our water heater replaced and had a great experience from start to finish. The team was professional, knowledgeable, and completed the installation quickly and efficiently. They explained everything clearly, cleaned up after the job, and made the whole process stress-free. The new water heater works perfectly, and we couldn’t be happier with the service. I would definitely recommend them to anyone needing water heater replacement or plumbing work!"

"I needed an 18yr tankless hot water heater removed and a new one installed. Mike and Brian came over and swapped it out with ease. Looks nice and neat and they took time to explain what they did and what to expect. I have rental property and Mike will be the 1st person I call in the future. 5-Stars all the way!"

"Angie sent me a plumber that wasn't going to be available until Monday morning, so I contacted All Trades and they were available to complete the installation of the new heater on Friday morning 7/15/22. They did a great job and I payed them by check for the installation and new AO Smith water heater. Great new water heater and a great job."

"Excellent work,made sure everything was working fine before leaving.I had diverters with springs in the back of them for a long time.I did not like them as they would break all the time.Cheap plastic.Brass valves and full turn knobs were put in.I love the new set.It is sturdy and will last a long time.Also a tub water stopper and a new over flow was put in along with new plastic pipe under the stopper.The stopper is great.All you have to do is step on it for water to go down or stay up.Very professional attitude.On time to do the work.Cleaned up after the job was done.Will hire for other work in the future."

"Purchased the deal in the evening on Friday Feb 12, 2016. At time of purchase I advised vendor that best way to reach me is by email or Angie's messaging. Also provided two possible dates in March for the work. Winston responded the next day via Angie's message, and we set up the service date for my  next weekday off, March 2. And I sent him some pictures of the plumbing and street valve. Could not get a commitment on an arrival time, but he called me that morning and advised he had a 9am dentist appointment, and would arrive after that. Showed up with his helper about 1.5 hours later. We could not get the street valve cover off, and thought it belonged to the city, so I made arrangements for Winston to come back today, March 15.
I called the city water dept, and they sent someone over, he said it was not their valve, it was mine and he couldn't touch it, I guess each city is different?.
Anyway, I got the cover off with the help of a saw, a big hammer and a pipe wrench in time for Winston to come back today. We communicated via Angie's messaging in the meantime. Still could not get commitment to arrival time, although I asked for 8am.
Called Winston at 8:15 this morning and he said he would be her by 9:15, arrived at  9:00. We could not get the street valve closed, it was stuck. Not surprised, as it has not been accessed in at least 30 years!. We decided he would put the new valve just downstream of my existing shutoff, and from now on, will not use the old one to prevent further leaks thru the valve stem packing. I also asked him to rebuild the hose bib in the garage adjacent to the main valve, and install heat tape on the pipe before wrapping it (I already had the heat tape, just never got around to installing it. When attempting to replace the washer in the hose bib, the retaining screw broke, so he installed a new hose bib into the old valve body for me. Although I was willing, Winston did not charge extra for the extra trip and the extras I asked him to do.
Overall, I am more than satisfied with this experience. My only complaint is not getting an advance commitment on arrival times. But once I did get a time, he was punctual, even early. Would give an A- on responsiveness if I could. But overall, an A experience!
Will definitely use A REAL PLUMBER again. In fact, we already discussed installing a freeze-proof valve for my backyard hose bib.
