On average, Perth households pay between $5–$15 per square metre for a deep clean and $35–$60 per square metre for a full re-grout; below you’ll find the DIY shortcuts, pro techniques and a hand-picked list of the city’s most trusted tile and grout specialists.
Tile and grout restoration goes far beyond a quick once-over with a mop. It lifts embedded mineral scale, scours away mould, replaces failing grout and locks everything down with a fresh sealer, restoring colour, hygiene and slip-resistance that everyday cleaning can’t touch.
Over the next few minutes you’ll learn how to assess your own floors, when a supermarket cleaner will do and when you need a qualified technician, exactly what each service tier costs, how to compare quotes line for line, which Perth companies consistently earn five-star reviews, and the maintenance habits that keep new grout looking crisp for years. Ready to bring back that showroom sparkle – let’s get started.
Step 1 – Understand What “Restoration” Entails Before You Start
Everyday mopping shifts surface dirt; restoration digs deeper. A technician will:
- break down fat-based and tannin stains with alkaline detergents
- dissolve mineral scale and soap scum with a safe‐acid descale
- remove and replace damaged grout, then re-silicone joints
- finish with an impregnating or topical sealer that locks out moisture and grime.
Common Perth tiles react differently to these steps:
- Ceramic – glaze shrugs off mild acids, but alkaline strippers can haze the shine.
- Porcelain – dense body survives heat extraction, yet needs pH-neutral rinse to avoid residue.
- Natural stone (travertine, marble, slate) – acids etch; only alkaline cleaners and stone-safe sealers.
- Terracotta & saltillo – porous, soaks up liquids fast; restoration must include penetrating sealer.
Why bother? Healthier air, mould prevention, higher resale value and longer tile life back up the PAA claim that “professional tile and grout cleaning is worth it.”
Restoration vs Replacement: A Cost–Time Comparison
| Service | Avg cost (Perth) | Downtime* |
|---|---|---|
| Routine mop/DIY clean | $2–$4 m² | Nil |
| Pro deep clean + seal | $5–$22 m² | 4 hrs dry |
| Full restoration (re-grout + seal) | $35–$60 m² | 24 hrs |
| Full tile replacement | $120–$200 m² + dump fees | 3–5 days |
*Excludes cure time for membranes; replacement also needs waterproofing and skip-bin hire, inflating costs.
Warning Signs Your Tiles Need More Than a Mop
- Grout looks patchy, crumbles when you rub it
- Dark mould keeps returning within days of cleaning
- White, powdery efflorescence on joints or edges
- Tiles sound hollow or shift underfoot
Quick checks: shine a torch across the floor to spot pinholes; drip water—if it soaks in, sealer has failed and restoration is due.
Step 2 – Inspect and Diagnose Your Surfaces Properly
Before you swing a scrub brush, spend ten minutes giving the floor a health check. Open the curtains, switch on down-lights and crouch to view the tiles side-on; raking light exposes haze, lippage and pinholes. Tap random tiles with the plastic end of a screwdriver—solid tiles give a crisp “tick”, loose ones echo. Log moisture with a cheap meter ($40 at Bunnings); readings under 6 % are normal, 7-10 % need ventilation, anything higher can derail tile and grout restoration. Photograph every defect from three angles so quotes and insurance claims are watertight. If mould is present, suit up with nitrile gloves and a P2 mask to keep spores out of your lungs.
Moisture, Efflorescence & Mould: What They Tell You
Perth’s sea-breeze humidity pushes shower grout past breaking point.
- Moisture meter: 0-6 % safe, 7-10 % caution, >10 % hidden leak probable.
- Hygrometer: aim for 45-55 % RH indoors.
- pH strips: rinse water above pH 9 hints at alkaline residue; below pH 6 signals acid damage.
Chalky white bloom (efflorescence) means salts are migrating—usually from a damp slab.
Call a Professional Immediately If…
- Sub-floor moisture tops 10 %
- Stone shows dull etch marks
- More than half the grout line is missing or soft
- You hear hollow tapping over wide areas
- Shower recess leaks or silicone is black behind the bead
Any one of these flags structural or waterproofing issues best handled by a licensed technician.
Step 3 – DIY Cleaning & Minor Restoration Techniques
Not every surface demands a tradie; some grime responds beautifully to a Saturday-morning blitz with gear you’ll find at Bunnings. The tricks below won’t replace full-scale tile and grout restoration, yet they can buy you months of extra life and keep mould at bay.
-
Bicarb paste + vinegar mist (ceramic & porcelain)
- Mix
3 tbsp bicarb + 1 tbsp waterto a spreadable paste. - Smear along grout, wait 5 minutes.
- Lightly spray equal-parts white vinegar; fizz lifts soap scum.
- Agitate with a nylon brush, mop with warm water.
- Mix
-
Oxygen-bleach soak for stubborn stains
- Dissolve
1 scoop (30 g) sodium percarbonatein 3 L hot water. - Flood tiles, keep wet 15 minutes (cover with plastic if needed).
- Scrub, rinse, towel-dry. Safe on coloured grout, avoids chlorine odour.
- Dissolve
-
Domestic steam clean + microfibre extraction
- Pass a 120 °C steam mop slowly over tiles.
- Immediately trail a dry microfibre pad to wick away suspended soil.
- Finish with a pH-neutral cleaner to neutralise minerals.
Tools & costs (approx.):
- Nylon grout brush $8, spray bottle $3, steam mop hire $35/day, oxygen bleach 1 kg $12.
- PPE: nitrile gloves, P2 mask, knee pads – under $20 total.
- Time budget: 8–12 min per square metre including setup and pack-down.
Using Grout Pens & Colourants For A Quick Refresh
Grout pens deposit a thin latex tint that whitens joints for 6–12 months—handy before inspections. For a longer fix (up to 5 years) choose a two-part colour sealer; it soaks in and cures rock-hard. Whichever you pick, scrub and dry the grout first, apply two light coats, then keep the floor traffic-free for 24 hours.
How To Re-Grout Small Areas Yourself
For hairline-cracked patches in the shower or behind the cooker:
- Fit a carbide blade to an oscillating multi-tool; rake out grout to 3 mm depth.
- Vacuum dust, wipe with methylated spirits.
- Mix matching grout (sanded for >3 mm joints, unsanded below that).
- Pack it firmly with a rubber float, wiping diagonally.
- After 20 minutes haze appears; polish off with a damp sponge.
- Let cure 48 hours, then seal with an impregnator. A 1 m² repair costs under $40 in consumables and keeps moisture from creeping behind the tile line.
Step 4 – Professional Restoration Methods Explained
When elbow-grease fails, trained technicians step in with industrial kit that cleans deeper, faster and safer than any hire machine. A professional tile and grout restoration starts with a patch test, then marries controlled chemistry with high-pressure extraction to pull years of grime out of the pores.
- Rotary scrubbers fitted with diamond or silicon-carbide pads
- Enclosed 1000 psi rinse heads connected to a truck-mount heat-vac system
- Portable HEPA wet extractors that leave the floor touch-dry in minutes
Typical sequence: 1) alkaline pre-spray (pH ≈ 11) dwells for 10 min to break oil films; 2) mechanical agitation lifts soil; 3) a safe-acid neutraliser (pH≈2.5) dissolves mineral scale; 4) 90 °C rinse flushes residues; 5) surface is blower-dried and balanced to pH 7 before an impregnating sealer is applied.
PAA asks, “Can you put new grout over old grout?” Pros will sometimes skim a 2 mm epoxy overlay when existing grout is sound but stained; if joints are cracked or more than 30 % missing, they grind out the lines to two-thirds depth first.
Full Re-Grouting & Waterproof Checks
After vacuuming the joint clean, specialists cut grout back 3–4 mm, probe the membrane for breaches and install antimicrobial, polymer-modified grout. Silicone expansion joints are re-tooled last. Expect apartments to start around $350 per shower; large family bathrooms climb to $1800.
Tile Repairs, Chip Fills & Replacement Matching
UV-cured resins rebuild small chips, while colour-matched fillers mimic original glaze sheen. If a tile must be swapped, technicians source stock from salvage yards or re-purpose extras hidden under the hot-water unit to keep patterns seamless.
Optional Upgrades: Colour-Enhancing & Anti-Slip Sealers
Topical coatings give a gloss or satin pop that lasts 2–4 years; penetrating enhancers enrich natural stone for up to a decade. Silica-based additives lift wet-pendulum slip ratings, ideal for alfresco and pool surrounds.
Step 5 – Perth Pricing Guide: What You’ll Pay in 2025
Restoration quotes still hinge on square-metreage, stain severity and access, but the averages below are what most Perth owners can expect this year:
| Service tier | Typical 2025 rate | What’s included |
|---|---|---|
| Basic machine clean | $5–$15 m² | Alkaline scrub + hot rinse |
| Clean + impregnating seal | $12–$22 m² | As above, then two sealer coats |
| Shower cubicle re-grout | $350–$600 each | Grind out grout, new polymer grout, silicone |
| Full bathroom re-grout | $900–$1,800 | Walls, floor, niches, sealing |
| Colour-seal makeover | $25–$40 m² | Deep clean + tinted epoxy overlay |
| Full strip-out & retile | $120–$200 m² | Demolition, waterproofing, new tiles |
Cost drivers:
- Natural stone or textured porcelain (slower to clean)
- Wide grout joints needing extra product
- Heavy efflorescence or mould treatment
- Multi-storey access or after-hours scheduling
Avoiding Hidden Extras
- Minimum call-out ($120–$150) still applies under 10 m²
- Furniture moving, skip-bin hire and CBD parking are rarely in the headline price
- Ask for a GST-inclusive, line-item quote with drying times and warranty length clearly stated

Step 6 – Selecting The Right Tile & Grout Pro In Perth
The difference between a floor that stays pristine for years and one that re-stains in weeks often comes down to the technician you choose. Look past cut-price flyers and focus on experience, insurance, specialised equipment and rock-solid warranties. Ask what chemicals they use, whether they patch-test sealers, and if their workmanship complies with AS 3958.1 and AS 3740. A proven satisfaction guarantee is your safety net.

Step 7 – After-Care To Keep Tiles & Grout Looking New
The job’s only half-done if you skip maintenance. Keep a neutral pH, manage moisture and set calendar reminders:
- Daily – quick spritz of pH-neutral cleaner, wipe with a dry microfibre pad.
- Weekly – warm-water mop plus neutral detergent; rinse and buff dry so minerals don’t re-crystallise.
- Monthly – torch-check grout for pinholes, test sealer by dripping water (it should bead).
- Yearly – re-silicone wet joints and book a professional inspection if high-use areas darken.
Door mats, shower squeegees and open windows slash dirt and humidity, extending sealer life to its full 2–10 year rating.
