- Damp behind the bath or under the tray
Signs you need bathroom resealing in Cowley
Mould is the reason many people want their sealant replaced. Steamy rooms that do not dry out keep the silicone damp for hours, and once it has grown into the bead, cleaning rarely gets it out.
Common reasons people contact us are:
- A reseal done over the top of the old bead
- Sealant that has split, shrunk or peeled away
- Water getting behind the kitchen upstand
- Lumpy, uneven sealant from a DIY attempt
Cowley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

About our bathroom resealing in Cowley
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Cowley. We are ARBOMaster approved and fully insured, and every job carries our 12-month guarantee. We work on shower trays & enclosures, sinks & splashbacks and basins & vanity units, and people most often call us about water getting behind the bath panel and sealant that has split, shrunk or peeled away.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Cowley, that’s a good reason to put tired sealant and grout right early.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints
To keep the joints looking good and working properly:
- Check the joints every few months for splits or lifting
- Run the extractor fan during and after every shower
- Keep scourers and sharp tools away from the bead
- Keep bottles off the sealant line
Good ventilation does more than any cleaner. Run the extractor fan during and after a shower, so the bead dries out between uses.
Each shower pushes a little more water through a failed joint. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Resealing early stops it.

What affects the cost of bathroom resealing
The quote reflects the job in front of us. We take into account:
- The type of sealant required
- The number and length of the joints
- Whether there’s mould to deal with
- How many areas need sealing
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The rough size of the job
- Where the job is, and your postcode
- How we’d reach the joints
- Whether it has been sealed before
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
How the job changes by surface
Kitchen worktops & upstands
The joint between worktop and wall takes splashes, crumbs and cleaning sprays. We seal them in a colour that suits the worktop, so the line does not stand out.
Baths
Baths move more than any other fitting, 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.
How it works
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes around two hours for one bath or shower, longer for a whole bathroom. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Cowley. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- The bead is tooled smooth and you’re told the cure time, usually around 24 hours.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area

Bathroom resealing around Cowley
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, which is why it’s worth fixing early.
For site and facilities teams at buildings such as Cowley St Laurence CofE Primary 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. Letting a property close to West Drayton station? Then mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

Cowley: your questions answered
Do you take on hotel work around Cowley?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Could a tired shower seal in my Cowley flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Can mouldy silicone be sorted out?
Yes, by replacing the sealant. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Good ventilation helps keep it away.
Do you guarantee your resealing?
Yes, for 12 months. Looking after the joint as we suggest helps it last.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How long does a bath or shower reseal take?
It takes half a day or less for one room, longer when the kitchen is included. We’ll confirm how long your job needs when we quote.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
