Seepage and damp walls only get worse with time. Our waterproofing specialists identify the true source of water ingress and apply the correct system — not a cosmetic patch.
Water is the most common cause of structural deterioration in Singapore buildings. Failed waterproofing leads to peeling paint, mould growth, damaged plaster, rusted reinforcement and unhappy neighbours downstairs.
RR Handyman Service provides complete waterproofing solutions — surface preparation, membrane application, PU grouting, injection and protective screeding — for bathrooms, kitchens, balconies, planter boxes, rooftops and external walls.

Common Fixes
Signs that your waterproofing has failed — and that we can help with.
What Singapore property owners usually want to know before waterproofing works.
Common signs include damp or discoloured patches on ceilings and walls, peeling paint, mould growth, a musty smell and water stains below wet areas. A moisture meter reading confirms it.
In most cases yes, because the waterproofing membrane sits below the tiles. Removing the screed and tiles allows us to apply a new membrane and test it properly. Injection is an alternative for specific leak points.
A typical bathroom takes about four to seven working days including hacking, waterproofing, ponding test and re-tiling, depending on the scope.
PU injection pumps expanding resin into cracks and joints to seal active leaks. It is ideal for slab leaks, construction joints and situations where hacking is not practical.
No. If the source is in the unit above, the repair must be done there. We can investigate and advise on the correct approach, and assist with coordination where needed.
Yes. We provide a written workmanship warranty on our waterproofing systems. The exact duration depends on the area and system used and is stated in your quotation.
Waterproofing is only as good as the preparation behind it.
We investigate where water is actually entering instead of simply coating the visible stain.
Bathrooms, balconies and rooftops need different systems. We match the material to the exposure and usage.
We do not cover up waterproofing until it has passed a water-tightness test.
We understand HDB and MCST requirements and help you coordinate access where the unit below is affected.
