What recent reviews say
Seven Engineering Group specialises in finding hidden water leaks under floors, behind walls, and beneath properties without breaking up tiles or unnecessary excavation. They use thermal imaging, ultrasound, and acoustic tools to pinpoint ruptures in underground pipes and concealed plumbing. Reviewers consistently praise the precision, minimal damage, and fast response, particularly for slab leaks, condo ceiling seeps, and industrial units across KL, Selangor, Penang, and Johor. The team explain findings clearly and provide written reports.
However, some customers report the company enforces a full-package inspection fee (quoted around RM2,000 for preliminary scanning) and will not reduce scope to a single area, causing frustration when only a small suspected leak zone needs checking. One past customer also experienced misdiagnosis that left the main leak unresolved. The firm claims 35+ years of operating history and serves government agencies, embassies, and residential clients across Malaysia.

Common questions
- Do you break tiles or walls to find leaks?
- No. They use thermal imaging, ultrasound, and acoustic tools to pinpoint leaks without unnecessary excavation. Reviewers report minimal hacking, only in the precise area needing repair.
- Can you check just one small area of suspected leakage?
- The firm requires booking a full-package inspection. One customer reported being quoted a full fee even when requesting a single area scan, and requests for reduced scope were not accommodated.
- Do you serve my area?
- Their website lists service areas in Kuala Lumpur, Selangor, Penang, Johor Bahru, Petaling Jaya, and Klang Valley. Contact them to confirm coverage for your specific location.
