Bathroom Resealing in Crofton Park
Baths, showers and worktops in Crofton Park need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cracked, shrunken or lifting silicone
- Water getting behind the kitchen upstand
- Damp behind the bath or under the tray
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Wipe the sealant dry after showering
- Run the extractor fan during and after every shower
- Give the silicone its full cure time
- Wipe up water along the back of the worktop
Don’t stand bottles along the bead, as they hold water against it. Squeegeeing the walls and tray after use helps the joint dry.
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. Early resealing closes the gap before damage is done.
Bathroom resealing in Crofton Park, done properly
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Crofton Park. We’re ARBOMaster approved and fully insured, and every job carries our 12-month guarantee. If you have black spots spreading through the bead and damp behind the bath or under the tray, we can put it right.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Crofton Park, that’s a good reason to put tired sealant and grout right early.
Every job comes with our 12-month guarantee, wherever you are in Greater London.

How we quote for bathroom resealing
There’s no set price list, because jobs vary so much. What we look at:
- The number and length of the joints
- How many areas need sealing
- The product the joint needs
- Access and height
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What to tell us for a quote
When you call or email, these details help:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- Pictures of the joints, sent by email
- If someone has resealed it before
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Crofton Park. It helps if you can point us to a visitor permit or a bay close to the door.
- First the area is protected and every bit of old sealant removed.
- The joint is cleaned, degreased and treated for mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We clear away and tell you when it can get wet, usually after around 24 hours.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
Ask for a quote
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll take it from there.
Advice
FAQs for Crofton Park
Can you help a landlord with a rental near Crofton Park station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is parking an issue for bathroom resealing in Crofton Park?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you guarantee your resealing?
Yes. Our one-year guarantee covers every job, and we’re ARBOMaster approved applicators.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you come to Crofton Park?
We do. Crofton Park is part of the area we cover.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Can I choose the colour of the sealant?
We can use white, clear or a colour to suit. Where the joint is on show, we match it to the surface.
What does bathroom resealing cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How the job changes by surface
Basins & vanity units
A vanity top has a joint along the wall and sometimes at the sides. Water that gets behind can damage the unit, so the joint is sealed in one unbroken line.
Wet rooms
Not every wet room leak is a sealant problem. We check the joints and say so if the fault looks to be elsewhere.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Tiles that have come away from the wall
- Cracked or missing grout between tiles (that’s regrouting)
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Letting agents and landlords in Crofton Park can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
What happens if it’s left?
A quick bead over the top of the old one might look better for a while, but it can’t stick to what’s underneath. It lifts, traps water and grows mould behind it. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Crofton Park, the repair is bigger than a sealant job.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

What bathroom resealing looks like in Crofton Park
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. 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.
Homes close to Church of St Hilda include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Crofton Park station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. As a London address, Crofton Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
