HEAR FROM SATISFIED CLIENTS

The plumber Marcial arrived on time, was very professional and explained the issue clearly before starting the repair. They did a fantastic job fixing several issues in one of my apartments and left the area spotless. I've been using their service for several years now and they have always taken care of me. If you are looking for an honest trustworthy company these are your guys. They go above and beyond to take care of their customers need. I would definitely recommend his company to anyone needing plumbing services.

I had Hilltown plumbing come over to look at a couple of problems my old home that I bought as is had. The Watermain was bad and the old PEX water system was poorly installed and funky looking. They fixed my Watermain and redid the whole pack system so quickly I was blown away. The work was beautiful and the price was very reasonable. Marcial is very experienced, smart, and honest. Highly recommended! I have found my forever Plumber. Oh did I mention that they show up when they say they will.

Called Marcial up because my old water heater broke down on me. He was super responsive and was able to come out next day to take a look. After talking through options and pricing, I decided to get it done same day which he accommodated. Everything was super fast, easy, and reasonable. Water is working great now. Wish all my contractor/handyman experiences were like this!

After trying everything to unclog my tub I made an appointment with Marciel. He was able to come same day which was amazing. He was very polite and considerate about wearing covers over his shoes. It took him about 10 min with a snake to pull out a big ball of hair. He said it was about 15 feet down. 10/10 would recommend.

They were prompt with responding to an emergency water pipe repair. Marcial came and provided a free estimate, broke down the work that was needed to be done, and was spot on with how long it would all take and cost. Pricing was competitive and the workmanship looks to be very solid. They are the first ones I'll call the next time I need this type of work done (which hopefully won't be for a while)
