How does regrouting actually work? Five steps: a free inspection with a moisture test, full removal of old grout and silicone, a waterproof epoxy regrout, sealing and clean-up — then curing guidance and a 10-year waterproof warranty. No tiles removed. Most showers finished in a single visit.
Regrouting replaces the failed grout and silicone that let water escape behind your tiles. The old grout is cut out completely, joints are cleaned, and new waterproof epoxy grout is applied — with flexible silicone (not grout) at every internal corner, because corners move and grout there cracks. Done to the waterproofing heights in AS 3740, the Australian Standard for domestic wet areas, a regrouted shower typically lasts many years with basic care.
How it works
No vague promises — this is the exact sequence your technician follows on every job.
Step 01
We look before we quote. A technician inspects your grout, silicone and tiles, then runs a moisture-meter test to find exactly where water is escaping. You get an honest diagnosis on the spot — and a fixed written quote that lists what's included, how long it takes, and the warranty period. No obligation.

Step 02
This is where cheap jobs cut corners. We mechanically cut out all the old, porous grout — never grout over the top (new grout over old typically cracks within 6–12 months). Every failed silicone joint is stripped back, the area is vacuumed and deep-cleaned so the new work bonds properly.

Step 03
We regrout with waterproof epoxy grout — the same class of product (e.g. Mapei Kerapoxy-type) Melbourne's specialist shower sealers use. It resists stains and mould, and never needs sealing. Colour-matched to your tiles. Internal corners and wall-to-floor junctions get flexible sanitary-grade silicone, never grout — grout in corners cracks and absorbs moisture.

Step 04
Cement-based grout gets a penetrating sealer (epoxy grout needs none). We detail every edge, protect your shower screen and fittings throughout, and leave the bathroom clean — no dust, no mess, no half-finished joints.

Step 05
Your technician tells you exactly when the shower is ready — typically light use within 24–48 hours with epoxy grout. You also get simple aftercare (pH-neutral cleaner, squeegee, ventilation) and our 10-year waterproof warranty on every complete shower regrout, backed by your automatic rights under Australian Consumer Law.

Honest advice
The honest answer most tradies skip. Regrouting is the right fix for most leaking showers — but not all of them. Here's how we tell the difference before you spend a dollar.
If regrouting won't solve it, we say so at the inspection — before any quote, not after.
The most common question we hear: “Do you need to remove my tiles?” No — the entire process works around your existing tiles, and your shower screen stays in place in most cases (we mask and protect it). That's why regrouting costs a fraction of a full renovation, with none of the dust, downtime or retiling.
Step 03, in depth
Standard cement grout is porous — it absorbs water, stains, grows mould, and needs a penetrating sealer plus resealing every year or two. Epoxy grout is a different material entirely: waterproof through its full depth, highly stain-resistant, and hostile to mould.

FAQ
The questions Melbourne customers actually ask us — and the answers we give on every job.
Most standard showers are finished in a single visit — the inspection takes about 30 minutes and the regrout itself usually takes a few hours depending on size. Balconies and whole bathrooms can take longer, and your fixed quote states the timeframe in writing.
