How we handle bathroom resealing in Westerham
Sealant is the soft line between a bath, shower or worktop and the wall. When it splits, shrinks or turns black, water gets behind it. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. We work on baths, basins & vanity units and sinks & splashbacks, and the jobs we see most are a bead that has pulled away from the tiles and mouldy sealant that has gone black.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Westerham are no different.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Should I try it myself first?
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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

What else we do in Westerham
Do you need bathroom resealing in Westerham?
Silicone needs a clean, dry surface without any grease to stick to. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.
Most people get in touch when they notice one of these:
- Water escaping at the shower enclosure
- Cracked, shrunken or lifting silicone
- Gaps between the worktop and the wall
- New sealant laid over old sealant that is now lifting
In the older streets around Church of St Mary the Virgin, older homes can move a little, which is hard on rigid grout and tired sealant.
Before you book anyone
- What guarantee comes with the work
- Whether they’re fully insured
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
What affects the quote in Westerham
Every job gets its own quote. This is what makes a difference:
- The old material and how stubborn it is
- Mould in or behind the old joints
- Working hours on commercial sites
- Whether the work is at height
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Where the property is
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or send us an email.
When it is not the sealant
Before booking, it’s worth knowing the limits:
- A leaking waste, trap or valve
- A bath or tray that moves because it isn’t properly supported
- Cracked or missing grout between tiles (that is regrouting)
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.
What we seal
- Sinks & splashbacks
- Basins & vanity units
- Shower trays & enclosures
- Kitchen worktops & upstands
- Wet rooms
- Baths
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Why it’s worth doing now in Westerham
Sorting it now is quick: it takes a morning or an afternoon for most single baths and showers. Left until water gets through, the job can grow to lifting panels, drying out and decorating. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
How long does it take to reseal a bath or shower?
It depends on how many joints there are and how much old sealant has to come out. For most single baths or showers, allow a couple of hours.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you come to Westerham?
Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Westerham.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Bathrooms and kitchens in Westerham
Westerham has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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.
If you let a flat or house near Hurst Green station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. Westerham is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
