How to compare waterproofing contractors in KL: diagnostic honesty, test-before-fix discipline, warranty scope and neighbour coordination.
Key takeaways
Practical guidance for KL & Selangor
Malaysian homes face tropical humidity, fast rain cycles, condo management rules, and mixed construction materials. That means the right method depends on surface condition, access, safety requirements, and whether water or structural movement is involved.
The safest approach is to shortlist the likely cause, collect clear photos, confirm the property type, and request an itemised fixed-price quotation. KL Servis Rumah confirms scope before work begins and avoids arbitrary pricing.

FAQs
How do I know a waterproofing contractor is honest?
They test before they sell — a water ponding test, membrane condition check, and documented diagnosis before recommending injection, surface coating or full membrane. A contractor who recommends a solution without testing is guessing.
Should the warranty cover the neighbour's ceiling?
The warranty should cover the waterproofing system against re-leak — damage to the neighbour's ceiling from a previous leak is typically handled through insurance, not the waterproofing warranty.
Is no-hack waterproofing always a scam?
No — PU injection and surface coatings work for specific problems. The scam is selling no-hack for every problem, including failed membranes that need full replacement. The diagnosis determines the method, not the contractor's preference.
How many quotes should I get for waterproofing?
At least two — if one says injection and the other says full membrane, ask both to show you the evidence for their recommendation. The contractor who tests and documents wins over the one who quotes without looking.
