How much does grout cleaning and silicone replacement cost
The cost comes down to the size of the area, how dirty the grout is, and how much silicone needs to be replaced. Minor dirt on a small section is fast and inexpensive to deal with. Deep mould worked into cement grout takes more time and needs mechanical cleaning. Replacing silicone around a bathtub or shower tray is priced separately. Consumables are included. You’ll find the current prices in the table below.
| Service | Price |
|---|---|
| Grout cleaning | 30–60 zł/m² |
| Silicone removal | 20–40 zł/mb |
Indicative prices. Ranges for a typical scope. Fixings included, materials separate. Minimum order 300 zł.

How the work is done
- You send photos of the grout and silicone — the technician checks how bad the contamination is.
- Tradespeople set a suitable date and time for the visit.
- At the property, the technician checks the grout type (cement or epoxy) and the condition of the silicone.
- Tradespeople apply a professional remover for mould and grime in grout (HG, Mellerud).
- Tradespeople clean the grout mechanically using a specialist scraper or multi-tool.
- Old silicone is removed in full: with a scraper and solvent.
- Fresh sanitary silicone is applied (Ceresit CS 25, Soudal): straight bead, no bubbles.
Common grout care mistakes
- Putting new silicone on top of old — it won’t stick properly and starts peeling within a month.
- Scrubbing grout with a wire brush: it scratches the tiles and ruins the grout.
- Using bleach on coloured grout: it strips out the colour.
- Not drying the surface before silicone application — no adhesion at all, and it peels off within a week.
- Buying universal silicone instead of sanitary: no anti-fungal additives, so mould comes back.
- Smoothing silicone with a finger without soapy water, the bead comes out uneven, with bubbles.

Case study: bathroom in Zoliborz
A flat in an older building in Zoliborz — 5 m² bathroom, Paradyz tiles installed 8 years ago. The grout between the tiles had gone black with mould, and the silicone around the Cersanit bathtub had fully detached. The client was thinking about replacing all the tiles. Tradespeople suggested another option: grout cleaning and silicone replacement. Tradespeople applied HG mould remover and left it on for 20 minutes. Then they cleaned the grout with a multi-tool attachment. The old silicone was cut out with a scraper, and the remaining residue was removed with solvent. The surface was degreased and dried. Tradespeople applied white Ceresit CS 25 sanitary silicone. The whole job took 3 hours. The client couldn’t believe it was the same tile: the grout looked brand new. The saving compared with retiling was huge. Conclusion: regular grout cleaning and replacing silicone on time can add years to the life of your bathroom.
Completed job

Frequently asked questions
Can I clean grout without replacing the silicone?
Yes, if the silicone is still in good shape, they can clean just the grout. But in many cases, when the grout is dirty, the silicone also needs to be changed.
What silicone do tradespeople use?
Sanitary grade: Ceresit CS 25 or Soudal: with anti-fungal additives. Tradespeople match the colour to your grout.
How long should I avoid using the bathroom after silicone replacement?
Give it at least 24 hours to cure fully. 48 hours is even better if you want maximum strength.
Can a tradesperson clean epoxy grout?
Yes, epoxy grout is easier to clean — it doesn’t soak up dirt. In most cases, a specialist product is enough.
How often should silicone be replaced?
On average, every 3-5 years. If mould shows up or the silicone starts peeling, it’s time to replace it.
Do tradespeople only work in bathrooms?
No, they also clean grout in kitchens, on balconies, and in hallways: anywhere with tiles.
What’s included in the price?
The technician’s labour, consumables (chemicals, silicone, scrapers), and travel. Re-grouting is priced separately.
Can a tradesperson re-grout the joints?
Yes, if the old grout is damaged, they remove it and apply new grout. That’s a separate service.
Are the chemicals safe for tiles?
Yes, they use products that are safe for ceramic and porcelain tiles. Tradespeople first test them on a hidden spot.
