About KL1 Plumber: Kuala Lumpur Plumbers Since 2012
KL1 Plumber is a locally founded plumbing specialist based in the Federal Territory of Kuala Lumpur, operating under the established Hong Seng Plumbing registry. We started as a local service provider and grew into a plumbing and structural repair firm covering the Klang Valley and beyond.

Bridging Plumbing and Waterproofing
Our mission is simple: transparent, professional and responsive help for homes and businesses. Over the years we noticed a gap. A plumber would fix a pipe, a roofer would patch a roof, and a waterproofer would coat a bathroom, but nobody owned the question of where the water was really coming from.
So we built a team that covers all three. Today KL1 Plumber handles general plumbing, emergency repairs, hidden leak detection, roof leak repair and structural waterproofing, plus tanks, booster pumps, water heaters and full bathroom overhauls.
We are proud of a consistent record of finding hidden structural leaks that standard plumbing companies often miss, and of pricing that people can understand before we pick up a tool.
KL1 Plumber starts operating in Kuala Lumpur under the Hong Seng Plumbing registry.
Services expand from general plumbing into leak detection, roof leak repair and waterproofing.
More than 600 residential and commercial customers served across the Klang Valley.
Dedicated teams in Johor Bahru and Penang, with coverage in Melaka, Ipoh and Seremban.
