Bathroom resealing in Cockfosters, done properly
Homes in Cockfosters have the same weak spots as anywhere else: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Each one is stripped, cleaned and dried before new silicone goes in. We work on sinks & splashbacks, kitchen worktops & upstands and shower trays & enclosures, and the jobs we see most are gaps between the worktop and the wall and smears of silicone across the tiles.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Cockfosters, bathroom resealing is as much about a room looking cared for as about keeping water out.
All of our work is guaranteed for twelve months.

Aftercare tips
A little care helps the new joints last. Our advice:
- Check the joints every few months for splits or lifting
- Wipe the sealant dry after showering
- Let new sealant cure fully before it gets wet
- Don’t leave water standing on kitchen joints
Good ventilation does more than any cleaner. Run the extractor fan during and after a shower, so the bead dries out between uses.
A failed kitchen joint is easy to miss. Splashes run behind the back edge and soak into the worktop, and the board underneath can swell. A reseal in time can save the worktop.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take around two hours for one bath or shower, longer for a whole bathroom. For a job in Cockfosters, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- 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.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

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.
Kitchen worktops & upstands
Laminate worktops swell if water gets into the core. A continuous bead along the back keeps water out.
What we cannot put right
We will not take on work that will not last, so these are the limits:
- A bath or tray that moves because it isn’t properly supported
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Failed grout lines across the wall
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Do you take on hotel work around Cockfosters?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do you come to Cockfosters?
Yes. We cover Cockfosters and the rest of Greater London, as part of our work across South East England, London and Scotland. To book, phone 0345 464 0079 or drop us an email.
Is it OK to put new sealant on top of the old bead?
No. Fresh silicone can’t stick to the old bead, so it peels away and hides mould and water. All the old sealant comes out first.
Can I choose the colour of the sealant?
Most people choose white or clear, but other colours can be used to suit tiles and worktops. Let us know your preference when you ask for a quote.
Do you guarantee your resealing?
Yes. All our work comes with a 12-month guarantee.
Where are you based?
Mr Mastic is based in Crawley. We cover Cockfosters and the rest of Greater London, along with the rest of our area.
How long does it take to reseal a bath or shower?
A single bath or shower takes about a couple of hours, including cutting out the old sealant. A full bathroom and kitchen can take most of a day.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why act early in Cockfosters
Leaving a split or mouldy bead only stores up trouble. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, turning a small job into a building repair. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Why book with us

Bathroom resealing around Cockfosters

For an older house near a landmark such as Christ Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near New Barnet station change hands often, and a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
