Intro
Many Singapore homeowners assume that any tiler can fix a leak by simply regouting the tiles. This is a dangerous misconception. Water travels along pipes and through concrete structures, so patching the visible symptom often ignores the root cause. I compiled this list to help you decide whether you need a full renovation package or a specialized repair. The difficulty lies in distinguishing between a design firm that bundles waterproofing as an add-on and a specialist who diagnoses structural failures. You are trying to protect your investment and avoid the cost of re-hacking tiles months later. The right choice depends on whether you are renovating a whole unit or fixing a specific leak in an HDB flat or condo.
Quick Picks
Choose Weiken Interior Design if you want a full bathroom renovation with tiling and waterproofing under one contract. Choose Lian Hin on a tighter budget if you only need to source matching tiles for a small patch. Choose Sika Singapore if you need the correct technical system specified for a complex leak like an RC roof.

How to Choose
| Criterion | Why it matters | What good looks like |
|---|---|---|
| Written waterproofing warranty | Waterproofing failures often show up months later. | A dated written warranty naming products, duration, and covered areas. |
| Method statement and materials named | Two quotes can be doing very different things. | The quote lists surface preparation, membrane brand, and number of coats. |
| Proof of registration and insurance | You want the contractor to carry the liability. | ACRA registration, HDB status, and current public liability insurance. |
| Diagnosis before quoting | Water travels, so guessing is dangerous. | They check the other side of the wall and use a moisture meter. |
| Track record on your building and leak type | Different property types have different failure modes. | Recent references for the same property type and symptom. |
| Quotation and payment structure | Vague pricing hides extras. | Itemised lines for hacking, disposal, and waterproofing. |
| After sales behaviour | The test is the call back, not the first visit. | A named contact and stated response time for warranty claims. |

FAQ
How much does it cost to waterproof a toilet in Singapore?
Costs vary significantly based on the extent of hacking required. A simple regouting job is cheaper than a full retiling. Expect to pay for labor, materials, and disposal of old tiles. Always ask for an itemized quote to understand where the money is going.
Do I have to hack all the tiles to fix a leaking bathroom, or can I just regrout?
Regrouting is only effective if the grout is the sole source of the leak. If the waterproofing membrane has failed, you must hack the tiles to expose the surface. A professional diagnosis is needed to determine the true cause.
My upstairs neighbour’s leak is staining my ceiling. Who pays and who do I engage?
If the leak originates from the common pipe or the neighbor’s unit, the responsibility lies with the MCST or the neighbor. You should report the issue to your MCST manager. They will coordinate the repair and determine the cost allocation.
Do I need HDB or MCST approval before hacking tiles and doing waterproofing?
Yes, you need approval for renovation work in HDB flats and condos. HDB has specific rules about renovation hours and safety. MCSTs may have additional guidelines for common areas or structural changes.
How long should a waterproofing warranty last and what should it cover?
A standard warranty lasts at least one year, but some contractors offer longer. It should cover both materials and labor for re-hacking and retiling. Ensure the warranty is in writing and specifies the products used.
