How bathroom resealing works in DA16
A fresh bead of silicone changes how a bathroom looks more than most people expect. Mouldy silicone makes even a new bathroom look neglected, and a clean white or clear joint fixes it quickly. It also seals the gaps that let water behind the bath. We work on basins & vanity units, baths and sinks & splashbacks, and common reasons people get in touch are smears of silicone across the tiles and sealant that has split, shrunk or peeled away.
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes two to three hours for a typical bath, depending on how much old sealant there is.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- Joints are degreased and any mould is treated.
- 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 are told the cure time, normally around 24 hours.

Where we work in DA16

London and the South East have homes from every era, from period terraces to post-war new towns and new estates. Each needs the right sealant for its age and materials, wherever it is in DA16.
Welling: For landlords with property near Welling station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. Homes close to St John's Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
What affects the cost of bathroom resealing
Every job gets its own quote. These are the things that affect it:
- When we can work, for business premises
- How easy the joints are to reach
- The size of the job
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, 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
You don’t need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- The address or postcode of the job
- How many joints, rooms or windows are involved
- A few photos by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Leave it or put it right?
Sorting it now is quick: the work takes two to three hours for a typical bath, depending on how much old sealant there is. Wait for a leak and you may be looking at panels off, drying out and redecorating too.
What your quote should include
- What happens if they find a problem under the old sealant
- What guarantee comes with the work
- Whether they seal over old material or remove it
- How long to leave it before use
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t leave water standing on kitchen joints
- Let new sealant cure fully before it gets wet
- Open a window or run the fan so the room dries
- Never pick at the silicone with a blade
Mould needs damp, so keep the room aired. Use the fan, or open a window, while you bathe and for a while afterwards, so the bead dries out between uses.
A few black dots in the silicone soon become a black line. When it has grown right through, it rarely cleans out, and nearby grout often goes the same way. Catching it early keeps it a simple reseal.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Signs you need bathroom resealing
Mould is the reason many people want their sealant replaced. Bathrooms without good ventilation keep the silicone damp for hours, and mould that has grown into the silicone usually won’t clean off.
Most people get in touch after spotting one of these:
- A messy, uneven bead from a previous reseal
- A bead that has pulled away from the tiles
- Water getting behind the kitchen upstand
- Water getting behind the bath panel
DA16: your questions answered
Can I do it myself?
That depends on the joint. 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 add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Is it OK to put new sealant on top of the old bead?
No, never. Sealing over the top looks fine for a few weeks, then lifts, because silicone doesn’t bond to silicone. Every trace of the old bead is removed first.
