A few months back we used S&J to replace every toilet in our home and then instal 2 sets of bathroom taps. Very satisfied. Just this week one of the tap handles was loose and the off position was out of alignment. I sent a short email, and not only did they immediately respond and take ownership of this minor issue, they had someone out in a few short hours to correct it. I was satisfied with the initial instal and very impressed with the follow-up! Support local business and business owners that live in our community.

TERRIBLE CUSTOMER SERVICE!! They quoted 180 for unclogging the drain, since they charge a two hour minimum labor... after 45 min of running a snake down the drain they ask for 280 for labor, helper and materials. They were not being upfront with additional surcharges. After talking to Jonathan, he cut out the helper cost, but he would not honor the quote we were given and asked for 245. They take cash payments without receipts - which is very shady... we wanted to pay by credit card, but they didn't have a credit card machine... It was just a bad experience all around and I will never use their

I required a valve replacement on a property that required shutoff at the towns side. Jonathon was very flexible in being available once the water was off and work ready to be done. Overall a good experience. The price was as quoted and the area left clean upon completion.

I have been using S and J plumbing for several years. Peter and his staff are extremely reliable, the quality of their work is excellent and they are always on time and courteous. In my opinion one of the best experiences from a plumbing company. I would highly recommend them to anyone.
