PU injection cost in Malaysia — real per-point market rates, how bills balloon, and ClickBina’s flat RM650 bathroom-ceiling rate from a Klang Valley contractor.

Almost every waterproofing contractor in Malaysia quotes injection work per point — one point being one drilled, packed and injected port. The table shows the going per-point market ranges in the Klang Valley for 2026; how the method itself works is covered in our PU injection waterproofing guide.
| Work type | Market rate (per point) | Typical use |
|---|---|---|
| PU injection — slab seepage, ceiling leaks | RM80 – RM250 | Homes, condos, dripping ceilings |
| PU grouting — tanks, lift pits, basements | RM120 – RM300 | Deeper structures, higher water pressure |
| Epoxy injection — structural cracks | RM150 – RM400 | Bonding cracked beams, columns, slabs |
| Minimum charge / small job | RM500 – RM800 whole job | Most crews will not mobilise below this |
All figures are indicative 2026, Klang Valley. The per-point number is only half the price — the other half is the count, and that is where quotes go sideways.
Per-point pricing sounds cheap — RM80! — but nobody can tell you the final point count before the drilling starts, and the person deciding the count is the person being paid per point. Here is how real jobs add up at typical Klang Valley rates of RM120–RM250 a point.
| Job | Typical points | Bill at RM120–RM250/point |
|---|---|---|
| Small localised drip | 5 | RM600 – RM1,250 |
| Standard bathroom ceiling | 8 | RM960 – RM2,000 |
| Master bathroom ceiling | 12 | RM1,440 – RM3,000 |
| Two bathrooms + balcony | 18–20 | RM2,160 – RM5,000 |
Notice that the RM80 headline rate almost never survives contact with a real ceiling: the crews advertising the lowest per-point figures are the ones with the strongest incentive to find more points once the packers are in.
Within the market range, several factors genuinely move the price, and a fair quote will name them. Access is the big one — a 4-metre stairwell ceiling or a lift pit costs more to work in than a standard bathroom soffit. Slab thickness and water pressure decide the injection pressure and how much resin each point swallows. Resin type matters: hydrophobic foam for fast waterstopping is priced differently from flexible hydrophilic gel for moving joints. Volume cuts both ways — a 20-point job should carry a lower unit rate than a 5-point one. Finally, travel and minimum charges load small jobs, and whether a written warranty is included changes what the number actually buys you. What none of these factors justify is a rate that only becomes clear after your ceiling is already drilled.
Four games show up again and again in Klang Valley injection quotes. The lowball anchor: advertise RM80 a point, then average RM180 once “your slab turns out thicker”. The mid-job discovery: six more points are “found” while your ceiling is already full of packers — refusing halfway through a drilled ceiling is not a real option, and the contractor knows it. The resin surcharge: a per-litre material charge appears on top of the per-point rate, uncapped. And vanish-after-payment: no written warranty, so when the drip returns in month two, the callback is a brand-new invoice. None of these are illegal; all of them are why we refuse to price home ceilings per point.
ClickBina charges RM650 flat for PU injection on one bathroom ceiling — diagnosis, unlimited points, patching and a 6-Month No-Leak Warranty included, priced in writing before we drill. Full details are on our PU injection ceiling leak service page. And here is the honest comparison: if your leak genuinely needs only three or four points and you can get that count fixed in writing at RM80–RM120 a point, a per-point quote can come in under RM650 — take it. In practice, most dripping ceilings need 8–12 points, the count is only confirmed after your ceiling is drilled, and the same jobs land at RM960–RM3,000. The flat rate buys cost certainty: the number you agree on WhatsApp is the number on the invoice, whatever the slab turns out to hide.
Per-point pricing is not a scam in itself — it is the standard, sensible model for large commercial and civil work. On a basement retaining wall, a podium carpark slab or a set of RC water tanks, the job may run to hundreds of points along tens of metres of joints. There, a professional contractor surveys first, agrees a measured point count and a transparent unit rate before mobilising, and the economics genuinely favour the client at scale. The problem is the same model transplanted to a single home ceiling, where there is no survey, no agreed count and no negotiating power once drilling starts. Fair per-point work is surveyed and counted upfront; predatory per-point work is counted afterwards.
Bigger structures are usually quoted as a whole job built up from the PU grouting rate of RM120–RM300 per point. These are realistic whole-job planning ranges (indicative 2026, Klang Valley) — actual figures follow a site survey of joint lengths and water pressure.
| Structure | Typical whole-job range | Notes |
|---|---|---|
| RC water tank (PU grouting) | RM1,500 – RM6,000 | Size, joint length and whether the tank can be drained |
| Lift pit | RM1,200 – RM4,500 | Confined access; often active groundwater pressure |
| Basement wall seepage | RM2,000 – RM10,000+ | Per wall section; length of cold joints drives cost |
| Carpark / podium slab section | RM3,000 – RM15,000+ | Usually surveyed and quoted per measured area |
For these structures, insist on the survey before the price: a contractor who quotes a serious tank or basement job from a photo alone is guessing with your money, and the gap between guess and invoice is rarely in your favour.
The other comparison worth making before you spend anything: injection versus redoing the waterproofing properly. Injection on a ceiling runs RM650–RM2,000; a full hack-and-redo of the bathroom above — hacking tiles, new membrane at RM6–RM18 per sq ft, screed and retiling — typically lands at RM3,500–RM8,000, as broken down in our bathroom waterproofing cost guide. Injection wins on price and speed when the leak is localised and the structure is sound. Re-waterproofing wins when the membrane has failed wholesale, when leaks keep appearing along new lines, or when you are renovating the bathroom anyway. Our injection vs membrane guide gives the full decision framework.
Whatever the pricing model, a professional injection quote should contain the same six things: an inspection (site visit or a proper video/photo diagnosis), a stated cause — what is actually leaking and why; a fixed, all-in price in writing; a defined scope (which ceiling, which points or area); the warranty period and what it covers; and what happens if the leak persists after the work. If a contractor cannot put those in a WhatsApp message before starting, that is your answer about how the invoice will behave afterwards. Our waterproofing quotation guide shows a full example and the red flags clause by clause.
The cheapest injection quote is usually the most expensive one, paid in instalments. A RM500 no-warranty job that fails in month two becomes a second RM500 job — or a down payment on the RM3,500+ re-waterproofing you were trying to avoid, now with a repainted ceiling on top. Price injection quotes as (fee) ÷ (months of dry ceiling the contractor is willing to guarantee in writing). ClickBina’s RM650 flat rate carries a 6-Month No-Leak Warranty: if the same leak returns within six months, we come back and fix it free. What separates a real warranty from a marketing line is covered in our waterproofing warranty guide.
ClickBina prices leak repair the way we would want to buy it: RM650 flat for one bathroom ceiling, points unlimited, warranty in writing, and an honest answer — including “this is a plumbing job, not an injection job” — before any drilling.
