Bathroom Resealing in Westminster
Problem with your baths, showers and worktops in Westminster? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- A joint torn by a bath that flexes
- A bead that has pulled away from the tiles
- Water escaping at the shower enclosure
Bathroom resealing in Westminster, done properly
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Westminster. We’re ARBOMaster approved and fully insured, and every job carries our one-year guarantee. We work on basins & vanity units, baths and wet rooms, and common reasons people get in touch are black mould in the silicone that won’t clean off and two layers of silicone, both failing.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Westminster are no different.
Big or small, you get the same 12-month guarantee.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Movement from a bath with loose feet or no proper support
- Tiles that have come away from the wall
- Water getting in through the grout rather than the sealant

How we quote for bathroom resealing
We quote each job individually. This is what makes a difference:
- How many areas need sealing
- The number and length of the joints
- How easy the joints are to reach
- The old material and how stubborn it is
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
When you call or email, these details help:
- Where the property is
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.
Leave it or put it right?
Running new silicone over the old joint can look tidy for a few weeks, but it cannot stick to what’s underneath. It lifts, traps water and grows mould behind it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Westminster, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear quote before we start.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a couple of hours for a single bath or shower in most cases. In Westminster, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- 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.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- Finally we tidy up and explain the cure time before we leave.
Before we arrive
- Clear the area around the work
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep scourers and sharp tools away from the bead
- Wipe the sealant dry after showering
- Move toiletries away from the joint
- Dry worktop joints after washing up
In a kitchen, don’t let water sit along the back of the worktop and keep hot pans away from the silicone. A dry joint lasts longer.
Worktop joints fail quietly. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. Resealing before that happens protects the worktop.

Questions from Westminster
Do you work in hotels near Westminster?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you help a landlord with a rental near London Victoria station?
Yes. We work for landlords and agents 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 will give you a clear quote.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you get rid of the black mould in my sealant?
Yes, by replacing the sealant. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Airing the room well helps stop it returning.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Does the resealing come with a guarantee?
Yes. Every job carries our one-year guarantee.
How long will the resealing take?
That depends on the number of joints and the state of the old sealant. Allow a couple of hours for a typical bath or shower.
How much does bathroom resealing cost in Westminster?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
