Andy and Felipe Lozano, the “Lozano Brothers” started a highly-concentrated commercial plumbing business in a two car garage in 1985. The Lozano Brothers’ understood how important it was to provide commercial plumbing and drainage services to their customers in a timely, courteous and professional manner in order to succeed. The name of their business became Plumbing Master and since it was a family owned and operated business they were able to go the extra mile to ensure that their customers’ received exceptional service. Plumbing Master came from humble beginnings but because of their deep plumbing traditions and hard working business ethics, they were able to grow into the flourishing, reputable company they are today. The Lozano Brothers are proud to say that much of their success was due to customer referrals, qualified technicians, quality craftsmanship and most importantly, satisfied customers. Today Plumbing Master provides services to restaurants, hospitals, convenience stores, municipalities, and commercial buildings spanning from Los Angeles County to San Diego County. With Plumbing Master’s twenty-five year history in commercial plumbing, we understand that plumbing problems can happen when least expected and we are dedicated to providing our customers with quick and timely service.
