How we handle bathroom resealing in New Addington
Showers work their sealant harder than baths. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. Each gets a bead of anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. We work on kitchen worktops & upstands, shower trays & enclosures and basins & vanity units, and the jobs we see most are leaking joints on a shower screen and water getting behind the bath panel.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in New Addington more than a cosmetic job.
All our work comes with a 12-month guarantee.

What we’re called out for in New Addington
Mould is the reason many people want their sealant replaced. Steamy rooms that don’t dry out keep the silicone damp for hours, and once it has grown into the bead, cleaning rarely gets it out.
These are the problems we are asked about most:
- Mouldy sealant that has gone black
- Leaking joints on a shower screen
- Gaps between the worktop and the wall
- Cracked, shrunken or lifting silicone
In the older streets around St Edward King and Confessor, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning or an afternoon for most single baths and showers and we leave things clean and tidy. In New Addington, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First the area is protected and every bit of old sealant removed.
- The joint is cleaned, degreased and treated for mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We clear away and tell you when it can get wet, normally after around 24 hours.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

New Addington homes and their sealant
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
If you look after a building such as Rowdown Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. New Addington is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Why it’s worth doing now in New Addington
Running new silicone over the old joint can look tidy for a few weeks, but it cannot stick to what’s underneath. Water creeps under it and mould follows. In a flat in New Addington, 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.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Your questions about bathroom resealing in New Addington
I live in a flat in New Addington. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Is parking an issue for bathroom resealing in New Addington?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
My sealant has gone black. Can you sort it?
Yes. We strip the bead, treat the joint and lay new anti-fungal silicone.
How long does the new silicone need before I use the shower?
Silicone is touch-dry quite quickly, but it takes longer to cure. Leave it around 24 hours before it gets wet, or follow the cure time we give you.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Let new sealant cure fully before it gets wet
- Keep scourers and sharp tools away from the bead
- Do not leave water standing on kitchen joints
- Stick to a soft cloth and a mild cleaner
Wipe up standing water along the worktop joint and keep hot pans off the bead. A dry joint lasts longer.
Each shower pushes a little more water through a failed joint. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Early resealing closes the gap before damage is done.

What the job involves on each surface
Shower trays & enclosures
Shower trays are sealed to the wall, and enclosures are sealed to the tray and tiles. Both take water every day, so both are resealed with anti-fungal sanitary silicone.
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.
