Bathroom & kitchen resealing in Southfields, Greater London
Baths, showers and worktops in Southfields need attention? We cut out the old, prepare the joints and apply the right sealant.
- Lumpy, uneven sealant from a DIY attempt
- Splits where the tray meets the wall
- Water getting behind the kitchen upstand
The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes around two hours for one bath or shower, longer for a whole bathroom. In Southfields, 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.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- We tool the bead to a neat finish and give you the cure time, generally around 24 hours.
How to prepare
- Tell us about any water getting in
- Mention any tricky access
- Clear items away from the joints we’re working on

Advice
About our bathroom resealing in Southfields
A bead that has gone black, split or come away is worth sorting before it lets water through. Just ring 0345 464 0079 or drop us an email with a photo of the joints, and we’ll give you a clear price for bathroom resealing in Southfields. We’re often asked to deal with gaps where the bath or tray has moved and water getting behind the bath panel, on wet rooms, kitchen worktops & upstands and sinks & splashbacks.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.

Common questions in Southfields
Can parking be tricky for a visit in Southfields?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Earlsfield station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Southfields, along with the rest of our area.
How do I get a quote for bathroom resealing in Southfields?
Size, access and the old material all affect the cost. Ask us for a quote.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you come to Southfields?
We do. Our applicators work in Southfields, and the service is the same as everywhere else.
Can you get rid of the black mould in my sealant?
Yes. Mould inside the bead rarely cleans out for good, so we cut it out, treat the joint and reseal with anti-fungal silicone.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What affects the quote in Southfields
Call for a quick quote. The main things that affect it are:
- How much there is to do
- Access and height
- Which sealant suits the joint
- The old material and how stubborn it is
The cost 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.
Asking for a quote
When you call or email, these details help:
- How we’d reach the joints
- A few pictures by email, if you can
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking

Signs you need bathroom resealing in Southfields
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.
Keep an eye out for any of the following:
- Gaps between the worktop and the wall
- Gaps where the bath or tray has moved
- Sealant that has split, shrunk or peeled away
- Damp behind the bath or under the tray
Southfields is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Aftercare tips
A little care helps the new joints last. We recommend:
- Do not let bottles sit on the bead
- Check the joints every few months for splits or lifting
- Dry the bead with a towel now and then
- Wait for the cure time we give you
Have a look at the joints every few months. Small splits and lifting ends are easy to catch early, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
A failed kitchen joint is easy to miss. 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.
When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Tiles that have come away from the wall
- A cracked shower tray or bath (that needs repair or replacement)
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Sinks & splashbacks

Bathroom resealing around Southfields
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
If you let a flat or house near Earlsfield station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. For site and facilities teams at buildings such as Floreat Wandsworth Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

What the job involves on each surface
Shower trays & enclosures
The vertical joint where a screen profile meets the wall is a common leak point. It’s resealed along with the tray joints, sealing the side the enclosure’s instructions call for.
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. We renew it in clear, white or a matched colour.
