Frequently asked questions

Straight answers to the questions we are asked most often across Sydney.

How much does waterproofing cost in Sydney?

A standard shower strip and re-seal starts at $495 and typically completes in one day. Balconies are priced from $145 per square metre, full bathroom membrane systems from around $1,250, and kitchens or splashback resealing from $395. Every quote we issue is fixed and itemised after seeing photos or completing an inspection — you will never receive a bill higher than the agreed price.

Do you actually remove tiles?

In the majority of cases, no. Around nine out of ten leaking showers we see are caused by failed grout and sealant at the wall-to-floor junction, which can be resolved with a complete strip, membrane and re-seal without touching a single tile. We will only recommend tile removal where the substrate or the existing membrane has genuinely failed, and we will show you the evidence before recommending it.

How quickly can someone attend?

Same-day appointments are usually available across metropolitan Sydney, and our emergency service operates 24 hours a day including weekends and public holidays. For an active leak that is causing damage we aim to have a crew on site within a few hours of your call to stop the water first, then quote the permanent repair.

How long until the shower can be used?

Membrane systems need between 24 and 48 hours to cure before water exposure depending on the product, temperature and humidity. We will always tell you the exact cure time for your job on the day, and for most shower reseals you can use the shower again the following day.

What does your warranty cover?

Our membrane systems carry a written structural warranty of up to 15 years and sealants up to 5 years, issued as a certificate with photographic records of the installation. The warranty covers labour and materials for the waterproofing work we performed. If anything we installed fails within that period, we return and rectify it at no cost.

Are you licensed and insured?

Yes. We hold full public liability and workmanship cover, our applicators are accredited for the membrane systems we install, and every completed job is documented and issued to you for your builder, tiler or insurer. Licence details appear on all quotes and invoices.

Do you work with insurers and body corpora?

Routinely. We prepare photographic investigation reports, scope-of-works documentation and certificates of compliance that insurers and strata schemes accept, and we can liaise directly with the appointed builder or assessor to keep the claim moving.

What areas do you service?

We cover all of metropolitan Sydney and most of greater NSW, including the Northern Beaches, the Blue Mountains, the Southern Highlands and the Hawkesbury. If you are just outside our radius, call us — we travel further for larger works.
