Abbas and Kollie were absolutely TOP NOTCH in EVERY REGARD! (Even my cat liked them and that's saying A LOT!) I will be sticking with Mallick until I keel over!!! Gentlemen, ULTRA professional and kind, sooo knowledgable. Work was done beautifully and changed my life around from this morning having found that the disposal had been apparently leajing for quite a while! It was a mess and having them arrive and make everything right means the WORLD to me. Thank you for running a business WITH ALL OF ITS DUCKS IN A ROW and DELIGHTFUL, TALENTED, EFFICIENT REPRESENTATIVES! A rarity these days. A++++++!

Dear Friends,
Today Billy and Kollie came to install our new water heater. They were amazing! They got the water heater installed, up and running without any issues. We are grateful for their hard work.
Warm regards, The Espejo family
Dear Friends, I hope all is well. We just had a great experience with Abbas a master plumber. He not installed plumbing fixtures flawlessly but he diagnosed some problems with water pressure because of original hardware. We were very happy with the visit.
Kind Regards,
The Espejo family

I've had Mallick plumbing under contract for years. They are always easy to schedule. Prompt, efficient and thorough. This time, I heard a weird sound in the wall when I ran hot water in the powder room that I hadn't noticed before. Mark and Ikam diagnosed it as thermal expansion and nothing to worry about which was a huge relief! 😀
