A waterproofing warranty in Singapore is published as a bare number and almost never as a set of terms. On 3 November 2026 we read eight Singapore waterproofing websites. Six promised a warranty, five named a period, and the periods ran from 12 months to up to 15 years. Three said what the warranty covers. Not one said what would void it.
A homeowner with a wet ceiling asks two questions before anything else: what will this cost, and what happens if it leaks again. The second question is the one these pages answer with a number and nothing else.
That gap is the finding. A buyer comparing a 12-month warranty with a 15-year one is comparing two numbers whose terms nobody has written down.

Row 4 is the one we would act on this week.
Why the warranty line is the one buyers read twice
Waterproofing is bought on fear of a repeat. The work is hidden under tiles or screed, the customer cannot inspect it, and the failure shows up months later as a stain on someone else's ceiling. So the warranty is not a bonus on the page. It is the product.
A number without terms is not a promise
That makes a bare number a weak promise. "12 months warranty" and "up to 15 years" tell a buyer nothing about whether a hairline crack from a neighbour's renovation is covered, whether the term restarts after a touch-up, or whether anyone will still be trading in year 14. Two of the six pages gestured at this without resolving it: one said the warranty "depends on your problems", another that coverage "depends on the areas of leakage and the materials we used". Both sentences are honest. Neither is usable.
Durability is not warranty
The language also drifts. On one site the homepage promised "10+ Years Waterproofing Durability" in its meta description, while another page on the same site advertised a "3-year warranty". Durability is a claim about a material. A warranty is a promise about who pays. A buyer reading the first number and signing on the second has been misled by accident.
Singapore's consumer law takes an interest in representations like that. The Competition and Consumer Commission of Singapore says "Section 4 of the CPFTA defines what is an 'unfair practice'" and that "the Second Schedule to the CPFTA sets out a non-exhaustive list of unfair practices". We are not lawyers and we offer no view on any particular page. The practical point stands on its own: a promise you cannot define is a promise you will argue about.
How we built the sample
We ran three searches through SingRank's self-hosted SearXNG metasearch on 3 November 2026: "toilet waterproofing singapore", "waterproofing contractor singapore" and "waterproofing singapore price". The first two phrases come back from Google Autocomplete as real queries, which is how we picked them rather than guessing.
From the results we kept Singapore businesses that do waterproofing or leak repair. We dropped a Wikipedia article, best-of listicles and directories, multi-trade marketplaces, a paint manufacturer, non-Singapore results and a set of spam blogs. One domain belonging to a business SingRank works for was replaced with the next result.
That left 11 sites. Two could not be measured: one timed out, and one refused our fetchers. So the technical audit covers 9 sites and 38 pages, and the hand-read of warranty, price and opening text covers 8 pages.
One of those nine is worth a line of its own. Its pages loaded for our audit crawler, and an hour later the same homepage served our reader "Please wait while your request is being verified". A bot check that fires on one fetcher and not another is a coin toss on whether a search or AI crawler sees your page at all, and we have written before about checking what a bot actually sees.
Only one page priced the work
One of the eight pages gave a figure for the job: "it ranges from $3 to $10 per square foot", inside an FAQ. A second page showed dollar prices, but for sealant and membrane sold in its online shop, from $140.00 to $245.00 — materials, not labour.
The other six described price without one. "Affordable & transparent pricing." "Clear quotations, no hidden fees." "At an attractive price." "Reasonable prices." One FAQ explained the position directly: the firm quotes after a free onsite inspection and "not over the phone".
We have sympathy for that. A toilet patch and a flat roof are not the same job, and a per-unit rate invites an argument on site. But our wider census found 99 of 211 Singapore service websites already show a price, so the trade is not unusual in being able to publish one. A square-foot band, a minimum callout, or a worked example of a typical HDB bathroom would each survive contact with reality.
Three openings forgot to say Singapore
Five of the eight opening paragraphs named the service and the country in the first 120 words. The three misses all named the service. All three left Singapore out of the opening paragraph, so it appeared only in the heading, the page title or further down.
This repeats what our AI search readiness study found across 109 local pages: the paragraph a machine is most likely to quote is the one owners write last. It is a sentence, not a rebuild.
The technical side was mostly fine
The parts an owner worries about were in better shape than the parts an owner writes.
All 9 audited sites served HTTPS. All 9 had a reachable robots.txt, and none of them disallowed our crawler or named GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot or PerplexityBot with a Disallow. One went further and named those crawlers with an explicit Allow. None of the 38 pages needed JavaScript to show its text.
Schema was the weaker half
Structured data was patchier. 7 of 9 sites declared a business entity. Four used a LocalBusiness type — schema.org describes HomeAndConstructionBusiness as "a LocalBusiness that provides services around homes and buildings", and lists GeneralContractor, Plumber and RoofingContractor among its subtypes. Three declared only a generic Organization. Two declared no business entity, and one of those nine carried no JSON-LD at all, no page title, no H1 and no viewport tag.
Eight of nine had a retrievable sitemap. One robots.txt pointed its sitemap at a different domain from the one we had fetched. Homepage server response ran from 81 ms to 5,066 ms, with 2 of 9 above two seconds.
What we would write this week
Three edits, in order, for a waterproofing or leak-repair business:
- Write the warranty terms out, on the page. The term in months or years, what it covers, what voids it, and what the customer has to do to keep it. Two sentences of exclusions beat a bigger number with none.
- Publish one real figure. A square-foot band, a minimum callout, or "a typical HDB common bathroom, non-hacking, is usually S$X to S$Y, confirmed after inspection". Any of the three answers the question the page currently deflects.
- Put the service and Singapore in the first sentence. Before the paragraph about humidity.
If your pages carry claims beyond the warranty, the same test applies to all of them, which is the argument in can you show the number. For the wider search side of the trade, our guide for renovation companies is the nearest fit.
What publishing your exclusions costs you
It costs you some enquiries. That is the honest version.
A page that says "the warranty does not cover movement cracks caused by later renovation works" will lose the buyer who wanted to hear that everything is covered forever. A page that names a price band will lose the buyer shopping only on price, who would have called and then gone elsewhere anyway.
What you get back is the argument you do not have in month 14, and a page a buyer can act on without phoning three firms. In our view that trade is worth making in a trade where the work is invisible. In our view it is not worth making if your terms genuinely vary job by job and you would be publishing a fiction. Write the real rule or write nothing.
And a point against our own side: none of this is search work. Six of these eight pages already rank for the searches we used. They are not short of visibility. They are short of a paragraph. You do not need an agency to write it.
Method and limits — read these before quoting
- Metasearch is not Google. Results came from SingRank's self-hosted SearXNG on 3 November 2026. Seven of its engines returned errors that day and most results came from one engine, so this is competitive shape, not Google's ranking.
- Small numbers. 11 sites attempted, 9 audited, 8 read by hand. One site's figures appear in the technical counts but not the hand-read counts, because it served our reader a bot check.
- One page per site. We read each site's main waterproofing page. A warranty written only on an inner page or in a PDF quote would not appear in our counts.
- Our reader is a fetcher, not a browser. Text added by JavaScript after load was not measured, though none of the 38 audited pages appeared to need it.
- We did not test any warranty. We measured what the pages say, not what any firm honours.
- No judgement of any business. This page names none, rates none, and alleges nothing against anyone.
Our method page sets out how we separate findings from assumptions.

FAQ
How long is a waterproofing warranty in Singapore?
It depends entirely on the firm, and the published range is wide. Of the eight Singapore waterproofing pages we read on 3 November 2026, five named a term: two said 12 months, one said one year, one said 1 to 10 years, and one said up to 15 years. Three of the eight named no term at all.
Should a waterproofing company publish its warranty exclusions?
In our view yes, because the exclusions are what the buyer is actually buying. None of the six pages we read that promised a warranty listed an exclusion or said what would void it. Writing two sentences on movement cracks, later renovation works and maintenance makes a shorter term more trustworthy than a longer bare one.
Do Singapore waterproofing websites show prices?
Rarely. One of the eight pages we read gave a figure for the work, a band of $3 to $10 per square foot in an FAQ. A second showed dollar prices for materials in its shop. The remaining six used words such as "affordable", "transparent" or "reasonable" with no number.
Do waterproofing sites block AI crawlers?
Not in our sample. All 9 sites we audited on 3 November 2026 had a reachable robots.txt, and none disallowed our crawler or blocked GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot or PerplexityBot. One named those crawlers with an explicit Allow.
Why does this study name no companies?
Because the finding is about a habit in the trade, not about any firm. Naming eight businesses would turn a measurement into an accusation, and the pages can change the week after we publish. We give the counts and the collection date so anyone can repeat the check.
Can I cite these figures?
Yes. Please cite "SingRank, Singapore waterproofing warranty study, 3 November 2026" with a link to this page. Quote each count with its base, such as 6 of 8 pages, and keep the metasearch caveat. Corrections are welcome through our contact page.
