Bathroom resealing in Battersea, done properly
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Battersea. We are fully insured ARBOMaster approved applicators, and every job carries our 12-month guarantee. If you have a reseal done over the top of the old bead and a joint torn by a bath that flexes, we can put it right, whatever the surface.
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 Battersea 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.

Do you need bathroom resealing in Battersea?
The wrong product fails fast. Decorators’ caulk and all-purpose sealants are not made for constant wetting, so they crack, discolour or grow mould quickly. Wet areas call for a sanitary silicone with an anti-fungal additive.
The problems people generally mention when they call are:
- New sealant laid over old sealant that is now lifting
- Smears of silicone across the tiles
- A joint torn by a bath that flexes
- Damp behind the bath or under the tray
If you look after a building such as Christ Church CofE Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Questions to ask before you book
- The length of the guarantee
- Whether the sealant suits the joint
- What the cure time is
- Which colour the sealant will be

What else we do in Battersea
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 each is cut out and renewed with anti-fungal sanitary silicone.
Sinks & splashbacks
The edge of an inset sink is a common place for water to get under the worktop. Where the sealant around the visible edge has failed, we renew it.
What bathroom resealing looks like in Battersea
Battersea 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.
As a London address, Battersea can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Clapham Junction station change hands often, and a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes half a day or less for one room, longer when the kitchen is included. In Battersea, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

Why act early in Battersea
Most of the work in a good reseal happens before any silicone goes on: removing all the old sealant, degreasing the joint, treating mould and drying it properly. Without that preparation, the new bead will not last. 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.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

Take a look at what affects the cost and customer reviews.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
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.
Questions from Battersea
Do you work for hotels and guest houses in Battersea?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you help a landlord with a rental near Clapham Junction station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you do kitchens as well as bathrooms?
Yes, often alongside a bathroom. Where it’s needed by the sink, we use a food-safe sealant.
Is it OK to put new sealant on top of the old bead?
No. It’s a common reason for reseals failing. The old joint is stripped, cleaned and resealed from scratch.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
