Common problems we fix in Anerley
Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants are not designed for a joint that’s wet every day, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
Look out for any of the following:
- Cracked, shrunken or lifting silicone
- A joint torn by a bath that flexes
- Black spots spreading through the bead
- Shrunken sealant along the back of a worktop
For an older house near a landmark such as St Paul's, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before booking
- How long to leave it before use
- How the surfaces are prepared before sealing
- How much experience the applicator has
- What insurance they hold

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clean with a mild bathroom cleaner and a soft cloth
- Check the joints every few months for splits or lifting
- Wipe the sealant dry after showering
- Wait for the cure time we give you
In a kitchen, don’t 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.
There’s no need to wait for a full refurbishment. Like paintwork, sealant needs renewing from time to time, and renewing it as soon as it fails protects everything around it.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How we quote for bathroom resealing
You’ll get a clear quote before we start. It’s based on:
- Access and height
- Which sealant suits the joint
- Any working-time requirements on site
- Whether there’s mould to deal with
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Whether it has been sealed before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
What happens if it’s left?
Most of the work in a good reseal happens before any silicone goes on: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Without that preparation, the new bead will not last. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Anerley, the repair is bigger than the sealant job would have been.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Damage behind the tiles that needs a tiler
- A tray or bath that is cracked through
- A bath or tray that moves because it is not properly supported
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

Common questions in Anerley
Can worn sealant in a flat in Anerley cause a leak downstairs?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. A proper reseal before the leak starts is the easy fix.
Do you work in hotels near Anerley?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Where do you work from?
Mr Mastic is based in Crawley. We cover Anerley and the rest of Greater London, along with the rest of our area.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Can you reseal around my kitchen sink and worktop?
Yes. Kitchen joints get extra degreasing before the new bead goes on, then we reseal in a colour to suit.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
Anerley homes and their sealant
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. London’s water is hard, which leaves limescale on sealant, grout and taps.
Anerley is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Managing a site like James Dixon Primary School? Then 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.

How it works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take half a day or less for one room, longer when the kitchen is included. In Anerley, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- We treat any mould and let the joint dry properly.
- 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.
How to prepare
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
