Mortlake homes and their sealant
London’s water is hard, which leaves limescale on sealant, grout and taps. 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.
If you live in an older home near All Saints' Church, older homes can move a little, which is hard on rigid grout and tired sealant. If you look after a building such as Thomson House 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.

About our bathroom resealing in Mortlake
It is not only bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water that gets into the back edge of a worktop can swell the board. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. If you have a reseal done over the top of the old bead and mouldy sealant that has gone black, we can help, on wet rooms, sinks & splashbacks and shower trays & enclosures alike.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Mortlake, getting the joints right keeps water where it belongs and the room looking clean.

Common questions in Mortlake
I live in a flat in Mortlake. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can you help a landlord with a rental near Mortlake station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is the work guaranteed?
Yes. Our 12-month guarantee covers every job, and we are ARBOMaster approved applicators.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Different surfaces, different methods
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Baths
A bath shifts slightly every time it’s filled, so we fill it with water before sealing. That way the joint is laid with the bath at its heaviest and is not torn the first time it’s used.
Aftercare tips
After the cure time, these simple habits help:
- Clean with a mild bathroom cleaner and a soft cloth
- Run the extractor fan during and after every shower
- Give the silicone its full cure time
- Keep scourers and sharp tools away from the bead
In a kitchen, don’t let water sit along the back of the worktop. The drier the joint stays, the longer it lasts.
Mould that starts as a few spots spreads through the bead. When it has grown right through, it rarely cleans out, and nearby grout often goes the same way. Replacing the sealant early keeps the job small.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes around two hours for one bath or shower, longer for a whole bathroom, and the area is left clean. In Mortlake, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- 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
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Advice
When to call us in Mortlake
Not every tube in the shop is meant for a shower. Decorators’ caulk and all-purpose sealants are not made for constant wetting, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
Most people get in touch after spotting one of these:
- Water getting behind the kitchen upstand
- Sealant that has split, shrunk or peeled away
- Damp behind the bath or under the tray
- Water escaping at the shower enclosure
For landlords with property near Mortlake station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
Before booking anyone
- How long to leave it before use
- Who does the work, and how experienced they are
- Whether they’re fully insured
- Which colour the sealant will be
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Why act early in Mortlake
Tired sealant is not a reason to replace a bath or shower. Replacing the joint is normally all it takes, as long as the fittings themselves are sound. If we find a deeper problem, you’ll hear it from us. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Mortlake.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
What you get with us
