Bathroom resealing for homes and businesses in Winchmore Hill
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Winchmore Hill. We’re fully insured ARBOMaster approved applicators, and every job carries our one-year guarantee. If you are dealing with mouldy sealant that has gone black and sealant that has split, shrunk or peeled away, we can help.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Winchmore Hill more than a cosmetic job.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

How the job changes by surface
Sinks & splashbacks
Where a splashback meets the worktop, there’s a joint that catches every splash. We renew it in clear, white or a matched colour.
Basins & vanity units
Basins take less water than showers, but the joint behind them is splashed every day. Old sealant there often goes black at the corners, so it’s cut out and renewed just like a bath joint.
What happens on the day
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a morning or an afternoon for most single baths and showers from start to finish. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Water getting in through the grout rather than the sealant
- Tiles that have come away from the wall
- Cracks in the tray itself rather than the joint
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Basins & vanity units
- Baths
- Wet rooms
- Sinks & splashbacks
- Shower trays & enclosures
- Kitchen worktops & upstands
What happens if it’s left?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which matters if you’re letting a property or selling it. A smeared, uneven DIY bead does the opposite. In a flat in Winchmore Hill, 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.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.
Why book with us

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Give the silicone its full cure time
- Use gentle cleaners on the silicone
- Do not leave water standing on kitchen joints
- Check the joints every few months for splits or lifting
Good ventilation does more than any cleaner. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.
There’s no need to wait for a full refurbishment. Like paintwork, sealant needs renewing from time to time, and renewing it as soon as it fails protects everything around it.
Signs you need bathroom resealing in Winchmore Hill
Plenty of failed sealant has been laid over the top of older sealant. New silicone will not bond to old silicone, so it lifts, lets water in and traps mould underneath.
Look out for any of the following:
- Failed sealant on the screen profile
- Smears of silicone across the tiles
- A joint torn by a bath that flexes
- Mouldy sealant that has gone black
Schools such as St. Paul's School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Bathrooms and kitchens in Winchmore Hill
London’s water is hard, so limescale builds up on sealant, grout and fittings. 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.
As a London address, Winchmore Hill can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Winchmore Hill station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Your questions about bathroom resealing in Winchmore Hill
I live in a flat in Winchmore Hill. 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 Winchmore Hill?
Parking in Winchmore Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What colours of sealant can you use?
There’s a choice: white, clear and colours to suit tiles and worktops. We will talk it through when we quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Is it OK to put new sealant on top of the old bead?
No. Fresh silicone can’t stick to the old bead, so it peels away and hides mould and water. We always take the old sealant out completely.
Do you cover Winchmore Hill?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Winchmore Hill.
Is the work guaranteed?
Yes, for 12 months. Looking after the joint as we suggest helps it last.
