Hear Their Rave Reviews of Mallick Plumbing & Heating
    "They made recommendations but no pressure."
    Mike and Connor did a fanatic job. 

    I called to have my water heater replaced. It was 20 years old and was leaking from one of the valves.  I called Mallick based off all the great Yelp reviews. I worked with Mike and Connor. They did a wonderful job of installing my water heater. They made recommendations but no pressure. 

    Educating the Customer:
    They also took the time to explain:
    * My old water heater vs the new water heater 
    * They labeled everything and explained the labels
    * How to bleed the pipes so in the winter there are no issues and
    * What do in case I need to turn off the water  
    This rarely happens that someone takes the time to make sure you are better informed and put you at ease.  This was really important to me. Before calling them, my basement area was gushing out water and it took me a couple of stressful minutes to find the shut-off valve.  I could not remember which valve was which.

    I would definitely recommend and use Mallick again. I really appreciate their timeliness, educating the customer and how professional they were.
