- Water getting behind the bath panel
- A bead that has pulled away from the tiles
- Lumpy, uneven sealant from a DIY attempt
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Sealant that is mouldy, cracked or peeling is worth sorting before it lets water through.

Typical jobs include a messy, uneven bead from a previous reseal and sealant that has split, shrunk or peeled away, on baths, wet rooms and shower trays & enclosures.

What the job involves on each surface
Baths
Acrylic baths give a little under load, and even steel and cast iron baths settle slightly when full. Loading the bath with water before sealing allows for it.
Sinks & splashbacks
Where a splashback meets the worktop, there’s a joint that catches every splash. It’s resealed in white, clear or a colour to suit.

How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. In Rayners Lane, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We cover the area around the joints we’re working on.
- Old sealant is sliced away and the residue removed.
- Mould is treated, then the joint is left to dry thoroughly.
- 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.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Clear items away from the joints we are working on

Questions from Rayners Lane
Could a tired shower seal in my Rayners Lane flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows 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 Rayners Lane?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you reseal around my kitchen sink and worktop?
Yes. Kitchen joints get extra degreasing before the new bead goes on, then we reseal in a colour to suit.
How long does a bath or shower reseal take?
It depends on how many joints there are and how much old sealant has to come out. Allow a couple of hours for a typical bath or shower.
Do you work in Rayners Lane?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Rayners Lane included.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Rayners Lane.
My sealant has gone black. Can you sort it?
Yes. Mould inside the bead rarely cleans out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.
Are you fully insured?
Yes. We’re fully insured.
What bathroom resealing looks like in Rayners Lane
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to St. Andrew’s Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. As a London address, Rayners Lane can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Northolt Park station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

What’s near Rayners Lane
In Rayners Lane, that means homes and buildings near Eastcote House Gardens, Pinner High School and Heathfield School. Rayners Lane’s nearest station is Northolt Park station, roughly 1.2 miles south-east of the centre. Nearby you will also find Clementine Churchill Hospital (1.9 miles east) and St. George's Shopping Centre (1.6 miles east). For a walk, there’s Northala Fields and Islip Manor Meadows.
What happens if it’s left?
Leaving a split or mouldy bead only stores up trouble. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, turning a small job into a building repair. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Doing several joints on one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Water getting in through the grout rather than the sealant
- A cracked shower tray or bath (that needs repair or replacement)
- Water coming from the plumbing rather than the joint

How to look after the new joints
So the new joints stay in good condition:
- Run the extractor fan during and after every shower
- Squeegee the walls and tray after use
- Wait for the cure time we give you
- Don’t leave water standing on kitchen joints
Wipe up standing water along the worktop joint and keep hot pans off the bead. The drier the joint stays, the longer it lasts.
Worktop joints fail quietly. Splashes run behind the back edge and soak into the worktop, where it can make the board swell. A reseal in time can save the worktop.
