Bathroom resealing in Merton
Resealing is a small job that makes a big difference. Black, patchy sealant makes clean tiles look tired, and a clean white or clear joint fixes it quickly. It also seals the gaps that let water behind the bath. If you have water escaping at the shower enclosure and damp behind the bath or under the tray, we can put it right, whatever the surface.
Somewhere as small as Merton, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Merton questions
Is Merton within the area you cover?
Yes. Merton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Bicester Village station?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
What information do you need?
Let us know what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Is white the only colour available?
White and clear are the most common choices, but other colours can be used to suit tiles and worktops. Tell us what you’d like when you get in touch.
How long does a bath or shower reseal take?
Allow around two hours for one bath or shower, longer for a whole bathroom. We will confirm how long your job needs when we quote.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Quotes for bathroom resealing in Merton
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The product the joint needs
- The size of the job
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- How we’d reach the joints
- A few pictures by email, if you can
- Where the job is, and your postcode
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved and give you a clear price.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Cracked or missing grout between tiles (that is regrouting)
- Tiles that have come away from the wall
- A bath or tray that moves because it isn’t properly supported
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
Surfaces we seal
- Baths
- Kitchen worktops & upstands
- Basins & vanity units
- Shower trays & enclosures
- Wet rooms
- Sinks & splashbacks
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Dry worktop joints after washing up
- Avoid abrasive pads on the sealant
- Keep an eye on the corners, where splits start
- Do not let bottles sit on the bead
In a kitchen, do not let water sit along the back of the worktop and keep hot pans off the bead. The drier the joint stays, the longer it lasts.
A split bead lets water through every time the bath or shower is used. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Resealing early stops it.
For landlords and businesses
Landlords and letting agents in Merton can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
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.
Why it’s worth doing now in Merton
Dealing with sealant early is a short job: 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. Around Merton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

- Arbo and Everbuild products
- Anti-fungal sanitary silicone in wet areas

What bathroom resealing looks like in Merton
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Homes close to Church of St Swithin include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. If you let a flat or house near Bicester Village station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes a couple of hours for a single bath or shower. In a small place like Merton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
