I recently called R&M Zarb Plumbing as the main entry water pipe was leaking underneath the entry concrete stair. The gentleman from R&M Zarb Plumbing quickly addressed the cause (The previous owner used silicon to seal the leaking before selling the house to us ) without damaging the entry stair, and fixed it carefully. This was finished in the morning before my office hour and saving my whole day. I would definitely recommend R&M Zarb Plumbing
