Bath resealing in Bryn without replacing anything
All of the old sealant is cut out, treat any mould, and apply fresh mould-resistant silicone. We reseal baths, showers, sinks and worktops, including the awkward bits behind the taps. Our technicians work on basins & vanity units, shower trays & enclosures and kitchen worktops & sinks, and people most frequently call us about discoloured, yellow sealant and water getting behind the bath or tray.
The work is guaranteed for twelve months. If something is not right in that time, we come back and put it right.

What bath resealing costs
There is no area surcharge for Bryn. What changes the price is:
- Doing more than one item at once
- The material
- Unusual colours or finishes
- The type of damage
The price depends on how much damage there is and what kind, the material and how many items we do on one visit. We give a fixed quote from your photos, so you know the cost before booking.
Quotes from your pictures
It only takes a minute to photograph the damage, and it saves a visit. Try to send:
- Any earlier repairs or coatings
- Natural light rather than flash
- Where you are, by postcode
- A close-up of the damage, in focus
If you are in Bryn and want a price, the easiest route is pictures: one close up, one from further back, plus your postcode. You will get a fixed quote with dates to choose from.
What a repair can’t fix
To be straight with you, some problems need a different fix:
- Tiles that move, until they’re refixed
- Movement in the bath or tray
- Hidden water damage
If in doubt, send pictures and we’ll say what we think.

Common problems we fix in Bryn
Sealant doesn’t last forever. Each shower leaves moisture and soap behind, which mould loves, and the joint flexes each time the bath fills.
Get in touch if you’ve noticed any of these:
- Silicone smeared on tiles
- Damp near the bath
- Silicone coming away from the tiles
- Gaps by the taps

Your questions about bath resealing in Bryn
Is it OK to have pets in the house?
Yes, as long as they stay out of the room we’re working in. We will let you know when it’s safe to use again.
Do you work in Bryn?
We do. Technicians travel to Bryn from across the region, with no extra charge for travel.
Can you price it without visiting?
Nearly always. If pictures don’t show enough, we will ask for another angle.
Why does mould come back so fast?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are happy for a repair to be arranged before the end of a tenancy.
Can you redo someone else’s repair?
Most of the time. Let us know what was used before.
What happens if you find more damage?
If we find something the pictures didn’t show, we explain it first. You decide whether to go ahead.
Do I need to be at home?
Yes. We need access to the room while we work, at a time we agree with you.
Should I try a DIY kit first?
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
What happens on the day
There’s not much you need to do on the day. Let us in and show us the room, and we will get on with it. Most visits take around two hours, including clearing up.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- 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.
Before we arrive
- Have somewhere for us to park nearby if possible
- Make sure the room can be ventilated
- Tell us about parking, stairs or access
How to get a price
You do not need a survey visit. Nearly every job can be priced from photos: send a close-up, a wider shot and your postcode, and we will reply with a fixed price.
Advice
Keeping it looking good
Looking after the surface is easy, and it makes a real difference:
- Keep the joints dry
- Clean the sealant gently and regularly
- Replace the seal when mould sets in
- Do not stand toiletries on the seal
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, and we’ll say if you need a builder or plumber.

Why it’s worth resealing in Bryn
Resealing is a small job. Putting off a reseal can let water reach the walls and floor, which costs far more to put right. Instead of hourly rates, we price the whole job up front. Damage, material and access decide it.
