Bath & shower resealing (mastic) in Merton, Greater London

- Stained silicone

What bath resealing costs
You won’t pay by the hour. The price depends on:
- The size and number of damaged areas
- Doing more than one item at once
- What the surface is made of
- The type of damage
Our prices are the same across the UK, with no extra for Merton. What changes the price is the job itself: the material, the amount of damage and how many items.
How to get a fixed quote
It only takes a minute to photograph the damage. Please include:
- Where you are, by postcode
- Details of any past repairs
- Daylight if possible, and no flash reflection
- A photo taken from further back
Email us photos of the damage and a wider shot of the entire item, and tell us you’re in Merton, and we’ll come back with a fixed quote.
How we handle bath resealing in Merton
Resealing is one of the simplest ways to protect your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and a new seal stops it. We are frequently asked to fix gaps in the seal and damp near the bath, in basins & vanity units, wet rooms and kitchen worktops & sinks.
Whatever the size of the job, it’s backed by a one-year guarantee.

Common problems we fix in Merton
Joints split if the bath or tray moves, frequently because it was sealed with the bath empty.
Clients usually contact us about:
- Silicone coming away from the tiles
- Discoloured, yellow sealant
- An untidy old seal
- Damp near the bath
Questions to ask before booking
- How soon you can use it again
- A fixed quote, and whether VAT is included
- The length of the guarantee and what it covers
- Whether there are any call-out or travel charges
Materials and what they mean for the repair
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Shower trays
Trays are sealed with weight on them, for the same reason.
How to look after the repair
Nothing complicated is needed:
- Air the room after use
- Clean the sealant gently and regularly
- Use the extractor fan
- Keep bottles off the joints
Avoid scraping the joints, and don’t stand bottles on the seal.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.
What happens on the day
The work is clean and fairly quiet, so you can carry on at home. Protection goes down first, then the job itself takes around two hours. Before we leave, we explain the curing time and the aftercare.
- The old silicone is cut out completely.
- Residue is removed and the joint cleaned.
- We treat mould and dry the joint thoroughly.
- We fill the bath, or weight the tray, to open the joint.
- We apply fresh mould-resistant silicone and tool a neat bead.
Preparing for the visit
- Clear toiletries, mats and anything else from around the area
- Plan for the room to be out of bounds to pets and children
- Ensure the area is dry
Getting a price
There’s no need for us to visit first. Nearly every job can be priced from pictures: send a close-up, a wider shot and your postcode, and we will reply with a fixed quote.
Related advice
Can I fix it myself?
If you’re set on a kit, follow its instructions closely and work on a clean, dry surface, and do not use it until it has fully cured. If it fails, we can still put it right.
It’s tempting to reach for a kit, but the repairs we redo most often are DIY ones that have discoloured or lifted. Getting it right first time is typically cheaper.

Merton: your questions answered
Is there any odour?
A little, depending on the job. Ventilation keeps it to a minimum, and it soon fades.
Can you redo someone else’s repair?
Generally, yes. Tell us what was done before.
Is it messy?
Very little mess: we sheet and mask everything nearby, and we leave the room clean.
What areas do you cover?
Across the UK, so Merton is covered. Prices do not change with location.
What happens once I’ve sent photos?
You will get a fixed quote back, plus dates. There is no obligation to book.
Do you work in Merton?
Yes. We cover the entire UK and come to Merton. Send photos and we’ll quote, or call 0345 017 0787.
Can new silicone go over old?
We always remove the old sealant completely. Fresh silicone does not stick to old.
Do you hold any accreditations?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Is resealing worth it?
Resealing is routine maintenance. Leaving split or mouldy sealant can let water reach the walls and floor, and that damage costs much more to fix. A few things move the price: access, material, the extent of the damage and whether we can do several items together. Send photos and you’ll get a fixed figure.
