Failed silicone out. Fresh silicone back in.

Proper sealant removal, cleaning and surface preparation matter just as much as applying the new sanitary silicone.

Mouldy and failed bathroom silicone before replacement

Before

Old bathroom silicone can become mouldy, split, peel away or lose adhesion around shower trays, baths and tiled wet areas.

Clean bathroom silicone after removal and replacement

After

Fresh sanitary silicone restores the joint around the wet area and gives the shower or bath edge a cleaner finish.

Bathroom resealing

Showers, baths, trays & basins

Showers & shower trays

Failed shower sealant around trays, enclosures and tiled edges removed and renewed where suitable.

Baths & bath screens

Mouldy, cracked or peeling silicone replaced around bath edges, bath screens and common splash zones.

Basins & smaller wet areas

Neat silicone resealing around bathroom basins, splashbacks and similar household wet areas.

When silicone has failed

More than a cosmetic tidy-up

Silicone that has split, lifted or separated can stop sealing the joint properly and allow water ingress behind trays, baths, tiles or surrounding finishes.

Mould that will not clean away

Once black mould and staining are embedded in old silicone sealant, replacement is often more effective than repeated cleaning.

Cracks, gaps or peeling

Visible gaps around shower trays, bath edges and tiled joints can indicate that the waterproof seal is no longer doing its job.

New-build snagging

Poorly finished or early-failing new-build silicone can be stripped back, cleaned, prepared properly and resealed.

The prepared joint is resealed neatly using bathroom-suitable sanitary silicone and left to cure.

Common questions

Silicone replacement FAQs

Do you remove the old silicone first?

Yes. Failed, mouldy or loose silicone sealant is removed before resealing rather than simply being covered over with fresh silicone.

Can you replace mouldy shower silicone?

Yes. If black mould and staining are within the old silicone, removing the failed sealant and applying fresh sanitary silicone is often the best way to refresh the joint.

Can you deal with poor silicone in a new-build bathroom?

Yes. Early peeling, gaps or untidy new-build silicone can often be removed and renewed once dust, grout haze or residue has been cleaned from the joint.

How long does silicone replacement take?

Smaller resealing jobs may take around one to two hours. Larger shower enclosures, multiple wet areas or badly failed sealant can take longer.

When can the shower or bath be used again?

The new sanitary silicone needs time to cure before getting wet. A typical guide is around 12–24 hours, but the exact curing time depends on the product, ventilation and conditions.
