The company has built a strong local reputation, with 29 Google reviews highlighting prompt response times, tidy workmanship, and technicians — including Shamol, Shalom and Saif — praised by name for their professionalism on jobs ranging from roof leak repairs to plumbing and light installations.
HM Waterproofing & Plumbing Pte Ltd provides waterproofing and plumbing services across Singapore, covering everything from residential roof and bathroom sealing to large-scale commercial and industrial waterproofing projects. The company positions itself around a straightforward promise: certified, expert protection against water damage that's built to last.
HM Waterproofing's service list covers most of the ways water causes problems in a building. On the residential side, that includes sealing solutions for roofs, walls and wet areas, plus dedicated bathroom waterproofing using modern techniques designed to hold up under constant moisture. For larger properties, the company offers heavy-duty commercial and industrial waterproofing systems using high-performance materials suited to demanding environments.
When water has already caused damage, the team handles water leakage repair — using tools to pinpoint hidden leaks before carrying out targeted, minimally disruptive fixes — as well as concrete repair for cracked or weakened sections, and wall seepage repair to eliminate dampness and mould risk at the source. The company also installs waterproofing membrane systems, flexible barriers suited to roofs and balconies, and provides general plumbing services covering pipe repairs and faulty fittings.
One notable specialism is rope access: rather than erecting bulky scaffolding, HM Waterproofing uses rope access techniques to safely reach high or restricted areas, particularly useful for façade work and exterior repairs. Combined with the company's stated preference for no-hacking methods where feasible, this approach aims to get waterproofing and repair work done with less disruption to a property and its occupants.
HM Waterproofing follows a three-stage process for every job. It starts with a thorough inspection to evaluate the property and identify problem areas, followed by installation using high-quality waterproofing materials and techniques suited to the specific surfaces involved. After that, the company offers ongoing maintenance and repair to keep waterproofing systems effective over the long term, rather than treating each job as a one-off fix.
The company also offers a free consultation and a free inspection upfront, aimed at helping property owners understand their waterproofing needs before committing to any work, along with 24/7 availability for urgent issues.
HM Waterproofing & Plumbing has built a solid reputation locally, reflected in 29 Google reviews. Clients repeatedly highlight promptness, tidiness and professionalism — one reviewer described the team as "efficient, knowledgeable, good value," while another recounted how technician Shamol "was able to confidently detect the issue and proposed the appropriate solution" for a roof leak affecting walls and lighting, going "over and beyond to touch up and clean up" afterward. Other reviews mention quick turnarounds for jobs like tap replacement (handled by Shalom) and combined plumbing and electrical work completed within an hour of a next-day appointment (handled by Saif). Multiple reviewers describe pricing as reasonable or competitive and say they would use the company again.
