Waterproofing services across the Klang Valley — flat transparent prices for PU injection, bathrooms, balconies, roofs, tanks and walls, with a 6-Month No-Leak Warranty.

Waterproofing is not one service but a family of them: sealing an active ceiling leak from below, rebuilding the waterproof layer in a bathroom, membraning a roof or balcony, sealing a water tank, or stopping seepage through an external wall. Each has its own method, price logic and failure modes, and the most common mistake homeowners make is buying the wrong one — paying for a ceiling patch when the real problem is the bathroom upstairs. ClickBina covers the full range across the Klang Valley with one operating principle: diagnose first, quote a flat itemised price, fix it properly, and warranty the work. No per-point counting games, no mystery variation orders halfway through. If you are not sure which service your problem needs, that is normal — a dripping ceiling can be a slab leak, a failed bathroom membrane upstairs, a burst pipe or roof water travelling sideways, and each points to a different line on the menu below. Start with a photo and let the diagnosis pick the service, not the other way around.
The table below is the honest planning menu (indicative 2026, Klang Valley). Every job still gets a proper inspection before we confirm a fixed price, because the right method depends on where the water is actually coming from.
| Service | Indicative price | Typical use |
|---|---|---|
| PU injection, bathroom ceiling leak | RM650 flat (ClickBina) | Condo ceiling drips from the unit above; market charges RM80 – RM250 per point |
| Bathroom / toilet re-waterproof (non-hacking) | RM1,500 – RM3,500 | Surface-applied system, tiles stay |
| Bathroom / toilet re-waterproof (with hacking) | RM4,500 – RM9,000 | Full strip, new membrane, retile |
| Balcony & wet-area membrane | RM6 – RM18 per sq ft | Liquid or cementitious membrane, supply and apply |
| Flat roof / rooftop membrane | RM6 – RM18 per sq ft (liquid) / RM8 – RM15 per sq ft (torch-on) | RC flat roofs, exposed decks |
| Water tank waterproofing | Quoted after inspection | Cementitious coating for RC tanks |
| External wall seepage treatment | Quoted by wall area | Elastomeric coating, crack repair, repointing |
The classic Klang Valley condo problem: water dripping through the bathroom ceiling from the unit above. The standard fix is polyurethane injection — drilling small ports and pumping expanding PU grout into the slab to seal the water path from below, no hacking, done in a few hours. The market prices this per point at RM80–RM250, which creates an obvious incentive to find more points once the pump is running. ClickBina charges RM650 flat for one bathroom ceiling — however many points it takes — with a 6-Month No-Leak Warranty. The full method, and why point-counting is designed to confuse you, is in our PU injection guide.
When a bathroom floor's waterproof layer has failed — staining the ceiling below or the wall next door — there are two honest routes. Non-hacking (RM1,500–RM3,500) applies a penetrating or surface sealing system over the existing tiles: cheaper, faster, and appropriate when the failure is moderate. Hacking (RM4,500–RM9,000) strips the floor back to slab, lays a proper new membrane with angle fillets and upturns, ponding-tests it, then retiles: the full rebuild, and the only real fix when the membrane is comprehensively gone. Which one your bathroom needs is a diagnosis question, not a sales question — and if you are the downstairs victim of someone else's bathroom, our inter-floor leakage guide explains who pays under strata rules.
Balconies fail the same way bathrooms do, with weather added. Ponding rain, UV, and movement cracks break down the original membrane, and water tracks into the room inside or the unit below. The fix is a liquid-applied or cementitious membrane at RM6–RM18 per sq ft supply-and-apply, with proper falls to the drainage outlet, sealed upturns at walls and door thresholds, and a flood test before any tiling goes back. Planter boxes and air-con ledges are treated the same way — they are the most commonly forgotten leak sources on a Malaysian balcony.
Flat RC roofs and rooftop decks take the full monsoon and are the biggest waterproofing jobs by area. Liquid membranes run RM6–RM18 per sq ft; torch-on bituminous membrane, the heavy-duty option for exposed flat roofs, runs RM8–RM15 per sq ft (indicative 2026, Klang Valley). Cost scales with area, so see our roof waterproofing cost guide and flat roof waterproofing guide for full worked budgets, and the roof repair cost guide if tiles, flashing or gutters are the actual culprit — on pitched roofs they usually are.
Two specialist corners of the trade. RC water tanks (rooftop or underground) are sealed from inside with potable-grade cementitious coatings after crack repair — priced after inspection because access and tank condition vary hugely. External walls that drink in rain and show as damp patches or peeling paint inside are treated with crack repair, repointing and elastomeric wall coatings, priced by wall area and access. If your damp wall faces the weather side and worsens after rain, start with our external wall seepage guide to understand the failure before anyone quotes you.

Step one: WhatsApp us photos of the leak and a short description — where it drips, when it started, what is above it. From photos alone we can usually name the likely cause and give a preliminary price the same day. Step two: a site inspection with a moisture meter to confirm the source, after which the price is fixed in writing — method, materials, scope, warranty, all itemised. Step three: the work itself, from a few hours for PU injection to several days for a hacking re-waterproof, with photos of the stages you cannot see, like the membrane before it disappears under new tiles. Step four: testing — ponding test for floors, hose test where relevant — then the written warranty. You always know the full price before we start.
PU injection work carries our 6-Month No-Leak Warranty: if the leak we treated comes back within six months, we return and re-inject free. We keep the number honest rather than impressive — a six-month warranty we always honour beats a ten-year warranty designed never to pay out, and the failure window for injection work is in those first months, which is exactly what the warranty covers. Membrane and re-waterproofing jobs carry written workmanship warranties stated on the quotation. What waterproofing warranties genuinely cover, and the exclusion games to watch for elsewhere, is unpacked in full in our warranty guide — five minutes of reading that pays for itself the first time a contractor waves a ten-year brochure at you. Whatever you are promised, insist it appears on the quotation itself: the period, what is covered, and exactly what the contractor will do if the water comes back. A warranty that lives only in a conversation is not a warranty.
Flat published pricing with no per-point counting games, diagnosis before quotation, itemised written quotes, stage photos of hidden work, and warranties we actually honour — that is the whole pitch. If you want to vet us the way we would tell you to vet anyone, read our guide on choosing a waterproofing contractor and check our quotation guide against the quote we send you. Then WhatsApp us a photo of the problem — we reply within the hour during working hours, and same-week inspection slots are usually available across the Klang Valley.
