Bath resealing in Cefn without replacing anything
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and resealing puts a stop to that. Whether it’s black mould in the sealant and leaks at the edges, we can typically put it right.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we can’t put right
In fairness, some problems need a different fix:
- Loose tiles, which need refixing first
- Gaps too big for silicone alone
- A bath or tray that moves, until its support is fixed
If in doubt, send photos and we’ll say what we think.

Repairs by material
Baths
Baths are resealed with water in them, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Signs you need bath resealing in Cefn
Joints split if the bath or tray moves, often because it was sealed while the bath was empty.
If you can see any of these, send us a picture:
- Black mould in the sealant
- Gaps in the seal
- Water getting behind the bath or tray
- Unsealed corners
What your quote should include

- What aftercare is recommended
Can I fix it myself?
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair will not last.
If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.
Questions from Cefn
Is there a guarantee?
Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.
What happens if you find more damage?
If we find something the photos didn’t show, we explain it first. The price only changes if you agree.
Is it worth repairing rather than replacing?
Normally, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. We will tell you honestly if replacement makes more sense.
How long does resealing take?
A bath or shower typically takes a couple of hours. It then needs time to cure.
Can tenants book a repair?
We are happy to deal with the tenant, landlord or agent. Just ensure the landlord agrees.
Are you accredited?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
My seal keeps tearing. Why?
Something is moving. If it keeps happening, the support may need fixing.
Can you repair something that’s been repaired before?
Generally, yes. Tell us what was done before.
What happens on the day
Visits start with a quick look at the job together, so there are no surprises. Next, we cover and mask everything nearby and the work begins. You can expect it to take about two hours for a bath, and we’ll keep you posted as we go.
- The surrounding area is protected and the joints masked.
- We remove the old sealant and every trace of residue.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- The bead is smoothed, the tape removed and the seal left to cure.
Getting ready for the visit
- Let us know if it has been repaired before
- Mention if the room is upstairs or in a flat
- Plan for the room to be out of bounds to pets and children
Ask for a price
A quote takes minutes to ask for: photograph the damage, then the whole bath or shower, add your postcode and send them over. What comes back is a fixed quote, not a guess.

How we price bath resealing
There are no hourly rates or hidden extras. The price is based on:
- Whether we combine several jobs
- The colour and finish to match
- The material
- The size and number of damaged areas
Compared with replacing, repairing generally costs far less, because there’s no removal, plumbing or making good. The quote lists exactly what you’re paying for.
Quotes from your photos
We price nearly every job from photos. This is what we need:
- One sharp close-up of the damage
- A wider photo showing the whole bath or shower
- The material, if you know it
- Natural light rather than flash
There’s no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we will reply with a fixed quote.
Work for landlords and builders
We carry out planned and one-off repairs for housing associations and facilities teams. A repair avoids taking out and refitting, which matters when someone is living in the home.
If you manage property in Cefn, we can repair and quote for several addresses together. Send pictures for each one and we will price them together.
