Woolwich Bathroom Resealing
Bath, shower, basin, wet room, worktop and sink resealing for householders, landlords and businesses in Woolwich. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Black mould in the silicone that won’t clean off
- Gaps where the bath or tray has moved
- Shrunken sealant along the back of a worktop
Signs you need bathroom resealing in Woolwich
Plenty of failed sealant has been laid over the top of older sealant. New silicone won’t bond to old silicone, so it lifts, lets water in and traps mould underneath.
Common reasons people contact us include:
- A joint torn by a bath that flexes
- Leaking joints on a shower screen
- Sealant that has split, shrunk or peeled away
- A reseal done over the top of the old bead
Woolwich is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- Is the old sealant removed completely?
- How long to leave it before use
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
Bathroom resealing in Woolwich
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water that gets into the back edge of a worktop can swell the board. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. Typical jobs include black mould in the silicone that won’t clean off and a reseal done over the top of the old bead, on wet rooms, sinks & splashbacks and baths.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Woolwich, getting the joints right keeps water where it belongs and the room looking clean.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

How we quote for bathroom resealing
For a quick quote, just ask. The main things that affect it are:
- The number and length of the joints
- Any mould that needs treating
- The type of sealant required
- Whether the work is at height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
To help us quote quickly, let us know:
- If someone has resealed it before
- Roughly how big the job is
- How we’d reach the joints
- Whether it’s a home or a business
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Woolwich and across Greater London. We can quote a run of properties together, and we are fully insured for the work.
Landlords and agents in Woolwich can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before work begins. It won’t solve:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Loose or hollow tiles, or failed tanking behind them
- A tray or bath that is cracked through
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Baths

Woolwich: your questions answered
Is parking an issue for bathroom resealing in Woolwich?
Parking in Woolwich, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you help a landlord with a rental near Woolwich Dockyard station?
Yes. We work for letting agents and landlords as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you reseal kitchen worktops and sinks too?
Yes. Kitchen joints get extra degreasing before the new bead goes on, then a colour-matched bead is laid.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can I choose the colour of the sealant?
Most people choose white or clear, and other colours are available to suit tiles, trays and worktops. Tell us what you’d like when you get in touch.
How much does bathroom resealing cost in Woolwich?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Surface by surface
Kitchen worktops & upstands
Worktop joints get wet and wiped every day. The new bead is colour-matched where it shows, so the line doesn’t stand out.
Shower trays & enclosures
If a tray moves underfoot, new silicone won’t last. Movement is checked before anything is resealed, and tell you if it needs re-bedding first.
Leave it or put it right?
Bleach and mould sprays may lighten black marks for a while, but where mould is inside the silicone it generally comes back. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Woolwich homes and their sealant
London has hard water, 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 landlords with property near Woolwich Dockyard station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. For site and facilities teams at buildings such as Mulgrave Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
