Bathroom resealing in North Cray, done properly
It is not only bathrooms. Worktop upstands, sink edges and splashback joints all take splashes every day, and water that gets into the back edge of a worktop can swell the board. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. Common call-outs are for two layers of silicone, both failing and a joint torn by a bath that flexes, on wet rooms, kitchen worktops & upstands and baths.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In North Cray, that’s a good reason to put tired sealant and grout right early.
A one-year guarantee comes with the work, just as it does everywhere we cover.

North Cray homes and their sealant
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. London has hard water, which leaves limescale on sealant, grout and taps.
If you let a flat or house near Albany Park station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. If you look after a building such as Royal Park Primary Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Signs you need bathroom resealing in North Cray
Silicone does not last for ever. Every shower, every splash and every wipe with a cleaner take their toll over the years, and how long it lasts comes down to use, cleaning and ventilation.
Look out for any of the following:
- Black mould in the silicone that will not clean off
- A reseal done over the top of the old bead
- Damp behind the bath or under the tray
- A bead that has pulled away from the tiles
North Cray is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What affects the cost of bathroom resealing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- Mould in or behind the old joints
- Working hours on commercial sites
- Which sealant suits the joint
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- The address or postcode of the job
- The rough size of the job
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, ring 0345 464 0079 or email us.
How the job changes by surface
Basins & vanity units
The back of a basin gets wet every time someone washes. Old sealant there often goes black at the corners, and we treat it exactly as we would a bath.
Shower trays & enclosures
There are generally two jobs in a shower: the tray-to-wall joint and the enclosure joints. Both get soaked every time the shower runs, so both are resealed with anti-fungal sanitary silicone.
FAQs for North Cray
Can you help a landlord with a rental near Albany Park station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Could a tired shower seal in my North Cray flat affect the neighbours below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How long does a bath or shower reseal 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.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Does the resealing come with a guarantee?
Yes. We give a 12-month guarantee on every job, and we are fully insured.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a morning or an afternoon for most single baths and showers. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in North Cray. It helps if you can point us to a visitor permit or a bay close to the door.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- 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.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
How to get a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Advice
Why deal with it now?
You don’t need a new bathroom because the sealant looks bad. A new bead often brings the whole room back, as long as the fittings themselves are sound. If we find a deeper problem, you’ll hear it from us. 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 North Cray, the repair is bigger than the sealant job would have been.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.
