Grout Cleaning and Silicone Replacement in Warsaw — Tiles Looking New Again
22.03.2026Grout Cleaning and Silicone Replacement in Warsaw — Tiles Looking New Again
Grout lines between tiles have darkened, the silicone in the bathroom has gone black and mouldy — a familiar sight in every other flat in Warsaw. Replacing tiles because of dirty grout makes no sense — professional cleaning and silicone replacement are enough. We work across all of Warsaw: bathrooms, kitchens, shower enclosures, balconies. We bring specialist chemicals and tools. After treatment, grout looks brand new, and fresh sanitary silicone from Ceresit or Soudal keeps the seal intact for years.
How much does grout cleaning and silicone replacement cost
The price depends on the area, the condition of the grout, and the amount of silicone to replace. Light soiling over a small area is quick and affordable. Deep mould embedded in cement grout takes longer and needs mechanical treatment. Silicone replacement around the bathtub or shower tray is a separate item. Consumables are included. Current prices are in the table below.
| Service | min | max |
|---|---|---|
| Grout cleaning | 20 zł/mb | 40 zł/mb |
| Silicone removal | 20 zł/mb | 40 zł/mb |
How the work is done
- You send photos of the grout and silicone — the technician assesses the level of contamination.
- We agree on a visit date and time.
- On site, the technician determines the grout type (cement or epoxy) and the state of the silicone.
- We apply a professional mould and dirt remover for grout (HG, Mellerud).
- We mechanically clean the grout with a specialist scraper or multi-tool.
- Old silicone is completely removed — with a scraper and solvent.
- Fresh sanitary silicone is applied (Ceresit CS 25, Soudal) — even bead, no bubbles.
Common grout care mistakes
- Applying new silicone over the old — it won’t bond and peels off within a month.
- Cleaning grout with a wire brush — scratches tiles and destroys the grout.
- Using bleach on coloured grout — bleaches out the colour.
- Not drying the surface before applying silicone — zero adhesion, it peels off within a week.
- Buying universal silicone instead of sanitary — no anti-fungal additives, mould returns.
- Smoothing silicone with a finger without soapy water — uneven bead, bubbles.
What to prepare before the technician arrives
- Remove all bottles, shelves, and mats from the bathroom.
- If there is a shower curtain or glass door — ensure access to the grout around the perimeter.
- Ventilate the bathroom — the technician will be working with chemicals.
- Specify the grout colour if matching is important.
- Photograph the problem areas and send them in advance.
- Ensure access to water.
- If there are children or pets — restrict their access to the bathroom during the work.
- Provide the intercom code and parking information.
Case study: bathroom in Zoliborz
A flat in an older building in Zoliborz — 5 m² bathroom, Paradyz tiles laid 8 years ago. Grout between tiles had gone black with mould, the silicone around the Cersanit bathtub had completely come away. The client was considering a full tile replacement. We offered an alternative: grout cleaning plus silicone replacement. We applied HG mould remover, left it for 20 minutes. We cleaned the grout with a multi-tool attachment. Old silicone was removed with a scraper, residue with solvent. The surface was degreased and dried. We applied white Ceresit CS 25 sanitary silicone. The job took 3 hours. The client couldn’t believe it was the same tile — the grout looked brand new. The saving compared to retiling was enormous. Takeaway: regular grout cleaning and timely silicone replacement extend the life of your bathroom by years.
Frequently asked questions
Can I clean grout without replacing the silicone?
Yes, if the silicone is in good condition we’ll just clean the grout. But usually if the grout is dirty, the silicone also needs replacing.
What silicone do you use?
Sanitary grade: Ceresit CS 25 or Soudal — with anti-fungal additives. We match the colour to your grout.
How long should I avoid using the bathroom after silicone replacement?
At least 24 hours for full curing. 48 hours is better for maximum strength.
Can you clean epoxy grout?
Yes, epoxy grout is easier to clean — it doesn’t absorb dirt. A specialist product is usually enough.
How often should silicone be replaced?
On average every 3-5 years. If mould appears or the silicone is peeling — it’s time.
Do you only work in bathrooms?
No, we also clean grout in kitchens, on balconies, and in hallways — anywhere there are tiles.
What’s included in the price?
The technician’s work, consumables (chemicals, silicone, scrapers), travel. Re-grouting is discussed separately.
Can you re-grout the joints?
Yes, if the old grout is damaged we remove it and re-grout. That’s a separate service.
Are the chemicals safe for tiles?
Yes, we use products safe for ceramic and porcelain tiles. We test on a hidden area first.
Do you offer a guarantee?
Yes, on the workmanship. The silicone carries the manufacturer’s warranty. If it fails due to our work, we fix it for free.
