How we handle bathroom resealing in Forestdale
Sealant is the soft line between a bath, shower or worktop and the wall. Once it cracks or goes mouldy, water starts to find its way through and into the wall or floor. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. We work on sinks & splashbacks, baths and kitchen worktops & upstands, and the jobs we see most are leaking joints on a shower screen and a messy, uneven bead from a previous reseal.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
All our work is covered by our one-year guarantee, wherever you are in Greater London.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep scourers and sharp tools away from the bead
- Keep the fan on for a while after bathing
- Keep an eye on the corners, where splits start
- Use gentle cleaners on the silicone
Do not stand bottles along the bead, because they trap water against the silicone. A quick squeegee after showering helps the joint dry.
Do not wait for a refit to deal with failed sealant. Sealant is a maintenance item, like the paint on a window frame, and renewing it as soon as it fails protects everything around it.

How the job changes by surface
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A continuous bead along the back keeps water out, as long as the worktop itself is firmly fixed.
Shower trays & enclosures
Water often gets past the wall profile of a shower enclosure. It’s resealed along with the tray joints, following the enclosure maker’s guidance on which side to seal.
What happens if it’s left?
Mould removers can fade the surface of a stained bead, but mould that has grown into the sealant tends to return. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. In a flat in Forestdale, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

FAQs for Forestdale
Can parking be tricky for a visit in Forestdale?
Parking in Forestdale, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Could a tired shower seal in my Forestdale flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.
How do I get a quote for bathroom resealing in Forestdale?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email and tell us what needs doing and where.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
How long will the resealing take?
That depends on the number of joints and the state of the old sealant. Allow a couple of hours for a typical bath or shower.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Common problems we fix in Forestdale
Sealing over old silicone is one of the commonest mistakes we find. Fresh silicone can’t grip the old bead underneath, so it lifts, lets water in and traps mould underneath.
Any of these means the joints need attention:
- Black spots spreading through the bead
- Splits where the tray meets the wall
- Cracked, shrunken or lifting silicone
- Failed sealant on the screen profile
Forestdale is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Bathroom resealing in Forestdale: local notes
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London’s water is hard, which leaves limescale on sealant, grout and taps.
Letting a property close to Sanderstead station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. If you live in an older home near St Francis, walls and floors in older homes can move, and sealant and grout show it first.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
