Recommended Customer Reviews

I just had an extremely disappointing experience with Guy Plumbing. After reading all of the reviews, I felt confident that they were the place to call.
I had a relatively easy job and expected a great outcome. We just moved into a newly renovated home. After a week, we had a blocked toilet. I found a few construction related items in the garbage disposal so I expected something like that possibly in the toilet. The gentleman arrived in a timely manor and was careful to keep the house clean. He sent the tool into the toilet and removed toilet paper and it flushed. Good, but he didn't send it down again to confirm that there isn't anything else there to prevent toilet paper catching there again. Hopefully our problem is solved, but a second check would have been appreciated.
The bathroom sink next to the toilet had an odor. It was draining fine, but try as I might to send cleansers down it to kill the smell nothing helped. I ask that the plumber take a look. He filled the sink to see if it drained and looked down the drain. He then told me that it wasn't blocked. I already knew that. It was the odor I wanted help with. He shrugged and suggested I try vinegar as he walked out the door.
Total visit time 10 minutes. I received the bill for 1 hour. I understand that there is a minimum service fee of 1 hour, but I expect the plumber to stay and fix the problem and not run out the door. When I called to complain, I was told that they only stay as long as the job is scheduled for because they have other appointments. So apparently my job was only scheduled for 10 minutes. What if the toilet problem had taken longer than 10 minutes? Would he have left mid job? If I tried to add something major without warning, fine, but taking the pipe below the sink apart to check for a reason for the smell is a small request.
I now get to call another plumber and take time out to meet them. I would have preferred to pay more and have my issues solved in one visit. Never again.

Today was the second time I've had Guy Plumbing solve and fix a plumbing problem after other ""24/7 emergency"" plumbers couldn't figure out the problem, couldn't determine exactly what was wrong, vastly overstated the seriousness of the problem or were just plain incompetent. The two Guy guys (last time, Troy; this time, Dan) were efficient, competent, prompt and clearly superior to anyone else I've dealt with about plumbing issues. In addition, their charges, while not cheap, are fair and reasonable. There is no question that I would recommend Guy Plumbing. They really know what they're doing.

I have used Guy Plumbing for the last time.
I purchased over $800 in new faucets, etc. from them. I was told that I could return items if the packaging was not ruined.
I had someone install a shower head that cost over $150. We saved the packaging, tried out the shower head, and I decided to return it. I asked my contractor to remove it and put it back in the packaging. I was not aware that it was slightly wet when he put it back. I wasn't trying to be sneaky - I really did not know that it was wet. I thought that it could be returned it since the packaging looked like new.
Guy Plumbing would not take it back. They said that they could not sell it again because it was used. I am sure if it had been totally dry, they would have let me bring it back. In a way, I can understand their reasoning, but it was their attitude that I did not like. They were not interested in me or my problem.
Usually small businesses will go the extra mile to satisfy the customer and insure that she/he will return. They were firm. I even suggested that they could use the shower head as a display model. They would not do anything.
I even shared with them that a kitchen faucet that I also purchased had to be adapted to work with my on- demand water heater. I suggested that they ask customers before they buy a faucet whether they have this type of water heater. It would save the customer quite a bit of time. They looked at me as if I was out of my mind. It would take too much for them to find out what type of water heater a customer had.
Service like theirs, I can do without.

My shower was broken. I called Guy plumbing and heating and signed up for 2 o'clock to 4 o'clock window. The reception staff was very courteous. plumber arrived at precisely 2 o'clock. He fixed my shower within 45 minutes. Was courteous, friendly and explained everything that he did. Great service.

Wow! Guy plumbing service rocks! I was given a specific time they would arrive to fix my broken sink, they arrived on time, same day, and fixed the broken hose within 15 minutes of arrival! Incredible! I didn't spend hours waiting for someone to arrive, I now have a functional sink again- So happy! (Except that now I have to wash all those dishes that piled up when the faucet broke last night...)
Thank you Guy Plumbing!!!!

Amazing customer service. They were not the best fit for me based on my problem. This was great information to have ahead of scheduling time and wasting time.
I would highly recommend using them!

Guy Plumbing is all the things a service business should be. Available by phone, returns calls promptly, is customer oriented, knowledgable, polite, respectful, skilled, professional and they get the job done. And they are nice people from the person who answers the phone and sets up your appointment to the person who comes to the house. They are #1 in our house!

How can I NOT write a 5 star!! I called with toilet problems...wouldn't flush, no tank water, etc. I have zero plumbing skills, etc. I called, she asked a few questions, suggested I do a few things while she waited on the phone with me...my toilet is fixed! How often does that happen? NOT! So they deserve 5 plus stars.

VERY knowledgeable, helpful, responsive, ethical, honest, and VERY NICE. Dave was unbelievably helpful and responsive to my recent toilet crisis (crisis for me, no brainer for him!). As previous reviewers have said, I totally trust these folks and this company. Which, sadly, is rather rare these days. I highly recommend this company for both plumbing and heating needs.

Loved them! So courteous and professional! Troy from GUY plumbing came out and knew exactly what was happening with our sewer back up problem. He was quick and efficient. Even fixed our shower temperature control handle so we could use it until another one was ordered.
