About our bath resealing in Cwm-mawr
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 resealing puts a stop to that. We work on kitchen worktops & sinks, shower trays & enclosures and baths, and the jobs we see most are black mould in the sealant and an untidy old seal.
The work is guaranteed for twelve months. If something isn’t right in that time, we come back and put it right.

Prices and what affects them
You’ll know the full cost before you book. We take into account:
- How many items we do on one visit
- How many areas need work
- How easy the damage is to reach
- Whether it’s a chip, crack, burn or wear
A repair is priced on what needs doing, not where you live. The full price is agreed before you book, with nothing added on the day.
Getting a price from pictures
Photographing the damage takes a minute, and it saves a visit. Please include:
- What it’s made of, if you know
- Something in shot to show the size
- Where you are, by postcode
- Details of any past repairs
Pricing is simple: snap the damage close up and then the whole item, send them over with your postcode, and we will reply with a fixed price. There is no charge for the quote and you’re under no obligation.
Honest limits
A repair is not right for every job, including:
- A flexing bath
- Rotten walls or floors behind the bath
- Very wide gaps that need a trim
If in doubt, send photos and we’ll say what we think.

Common questions in Cwm-mawr
Can you reseal over the old silicone?
All the old sealant comes out. Fresh silicone does not stick to old.
How long does silicone take to cure?
Generally after around 24 hours. We will tell you the exact time.
What information do you need?
Just photos, your postcode and a contact number. On the day, we only need access to the room.
Is there any odour?
A little, depending on the job. Open windows and an extractor fan help.
Will it make a mess?
No. The work area is masked and covered, and we take our waste away with us.
Can you repair something that’s been repaired before?
Most of the time. Tell us what was done before.
What does bath resealing cost?
Because every job differs, we price from photos. You will get a fixed figure before you book.
Can you do more than one item on the same visit?
Yes. Combining jobs on one visit brings the cost down. Send photos of everything you’d like done.
What we do, step by step
We turn up at the time we agreed with you, introduces themselves and checks the damage against your photos first. Dust sheets and masking tape go down before any work starts. Most visits take about two hours for a bath, and we leave the room as we found it.
- All the old sealant is cut out and removed.
- The joint is cleaned and any mould treated.
- We dry the joint thoroughly.
- For a bath, we fill it with water first so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
Preparing for the visit
- Let the surface dry out before the visit
- Tell us if there are stairs or a lift
- Keep pets and children out of the room while we work

What your bath or shower is made of matters
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Can I fix it myself?
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.
If you’re set on a kit, follow its instructions closely, make sure the area is clean and completely dry, and give it the full curing time. If it does not work out, we can still repair it properly.
How to care for the repair
After the repair has cured, a few habits help it last:
- Clean the joints with a mild cleaner
- Open a window after bathing
- Use the extractor fan
- Keep bottles off the joints
Let it cure fully before using the bath or shower, normally about a day.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.
Do you need bath resealing in Cwm-mawr?
No sealant lasts for ever. Each shower leaves moisture and soap behind, which mould loves, and the joint moves slightly every time the bath is filled.
Common reasons people in Cwm-mawr contact us are:
- Mould you cannot clean out
- A messy previous reseal
- Stained silicone
- Leaks at the edges
