Bath Resealing in Llancaiach
Fixed-price bath resealing in Llancaiach and the surrounding area, done in a single visit in most cases.
- Black spots in the silicone
- Sealant that’s split or lifting
- Discoloured, yellow sealant
How we handle bath resealing in Llancaiach
The key to a good reseal is getting all of the old silicone out. Fresh sealant does not stick to old, which is why so many DIY reseals peel. We are often asked to fix gaps in the seal and a messy previous reseal, in shower trays & enclosures, baths and wet rooms.
Big or small, you get the same one-year guarantee in Llancaiach and across Merthyr Tydfil.

Prices and what affects them
A fixed quote means you know the cost before you book. We look at:
- How many items we do on one visit
- How many areas need work
- The colour and finish to match
- Where the damage is and how we get to it
Set against the cost of replacement, a repair is generally a fraction of the price, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.
How to get a fixed quote
We price nearly every job from pictures. This is what to send:
- A clear, close picture of the problem area
- Daylight if possible, and no flash reflection
- Any details about the material
- Any earlier repairs or coatings
Getting a quote takes a couple of minutes: take one close-up and one wider shot of the bath or shower, include your postcode and send them over. You’ll get a fixed price, not an estimate.
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.
Common questions in Llancaiach
Why does the silicone keep cracking?
Something is moving. If it keeps happening, the support may need fixing.
Will you leave a mess?
We protect the room with dust sheets and masking first, and we clean up when we have finished.
Is it worth repairing rather than replacing?
Typically, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we’ll say so.
Can you price it without visiting?
Yes, almost always. A close-up and a wider photo are enough to give a fixed quote.
Do you seal over the old sealant?
Never over old. It’s removed, cleaned off and the joint dried first.
Do you hold any accreditations?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
How do I stop mould in sealant?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
Will the price change on the day?
If we find something the photos didn’t show, we explain it first. You decide whether to go ahead.
What we do, step by step
We agree an arrival time beforehand, so you know when to expect us. Once we’re there, the work takes a couple of hours. We leave the room clean and you will know when it can be used.
- We cut out all of the old sealant.
- 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.
- New mould-resistant silicone is applied and tooled neatly.
How to prepare
- Have somewhere for us to park nearby if possible
- Clear the area around the damage
- Let the surface dry out before the visit

When to call us in Llancaiach
In time, even good sealant discolours, especially in a busy family bathroom. Steam, soap and movement all take their toll.
These are the problems we’re asked about most:
- Discoloured, yellow sealant
- Mould you can’t clean out
- Gaps in the seal
- Water getting behind the bath or tray
Comparing quotes
- Is the price fixed, and does it include VAT?
- How your room will be protected
- Whether a trained technician does the job
- What aftercare is recommended
Should I try a DIY kit first?
We understand the appeal of fixing it 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.
If you are set on a kit, follow its instructions closely, ensure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.
Honest limits
We’d rather lose a job than do one that will not last, so here’s what a repair can’t put right:
- Hidden water damage
- Gaps too big for silicone alone
- A bath or tray that moves, until its support is fixed
Send us pictures and we’ll tell you honestly.
What we work on
- Basins & vanity units
- Shower trays & enclosures
- Wet rooms
- Baths
- Kitchen worktops & sinks
Work for landlords and builders
We work for landlords, letting agents and housing providers in Llancaiach as well as householders. A repair between tenants keeps the property empty for less time, and it generally costs far less than a refit.
Housing associations and facilities teams use us for planned and reactive repairs. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.
Why reseal now?
A reseal is one of the cheapest bathroom jobs there is. Leaving failed sealant can let water cause damage that costs far more to fix. We charge the same wherever you are, with no extra for Llancaiach. What changes the price is the job itself: how much damage, what it’s made of and how many items.
What you get with us
- Free fixed quotes from pictures
- We leave the room as we found it
- CHAS, Constructionline and SafeContractor accredited
- Work done at your home or business
