How we handle bath resealing in Cefn-bryn-brain
A fresh seal protects your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and a new seal stops it. Typical jobs include silicone smeared on tiles and gaps in the seal, in basins & vanity units, baths and kitchen worktops & sinks.
Every repair is covered by a one-year guarantee, wherever you are in Powys.

Landlord and trade work in Cefn-bryn-brain
Builders, developers and site managers book us for snagging repairs, fixing chips and scratches before handover so nothing needs replacing. We hold CHAS, Constructionline and SafeContractor accreditations.
We regularly price jobs from inventory or check-out pictures. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.
Common questions in Cefn-bryn-brain
When can I use the bath after resealing?
You will get the curing time from us.
What do you need from me?
Use the quote form or ring 0345 017 0787, and we will do the rest.
Do I have to be there?
Someone needs to let us in and show us the job. After that, you can carry on with your day.
What if the damage is worse than the pictures show?
It’s rare, but if it happens we talk to you first. The price only changes if you agree.
What happens once I’ve sent pictures?
We look at the photos and reply with a fixed price and some dates. If anything’s unclear, we will ask for another photo.
Can you redo someone else’s repair?
Yes, we often do. Removing the old work can add time, and that is in the quote.
Is repairing better than replacing?
In most cases, yes. A repair skips the removal, fitting and redecorating. We’ll be honest if it’s not worth it.
Do you come to Cefn-bryn-brain?
We do. Repair technicians travel to Cefn-bryn-brain from across the region, with no extra charge for travel.
Prices and what affects them
Prices are worked out job by job. What matters most is:
- The type of damage
- The colour and finish to match
- Any earlier repairs that need removing first
- The size and number of damaged areas
The price depends on how much damage there is and what kind, the material and how many jobs we combine into one visit. You get a fixed price from your photos, so there are no surprises on the day.
How to get a fixed quote
When you take your pictures, these tips help us give you a firm price:
- Daylight if possible, and no flash reflection
- A coin or ruler next to the damage for scale
- What it’s made of, if you know
- Whether it’s been repaired or coated before
Most customers in Cefn-bryn-brain get their price from pictures. Tell us what happened and where you are, and we will send back a fixed quote and some dates.
When to call us in Cefn-bryn-brain
Sealant splits when the bath or tray moves, often because it was sealed while the bath was empty.
Send us a photo if you notice any of these:
- Discoloured, yellow sealant
- Sealant that is split or lifting
- Missing sealant behind the taps
- Water getting behind the bath or tray
What your quote should include
- A fixed price, and whether VAT is included
- How the room is protected while they work
- Whether the colour is mixed to match
- Whether cleaning and preparation are in the price
Aftercare tips
So the finish stays in good condition:
- Give the seal a regular clean
- Reseal at the first sign of lifting
- Use the extractor fan
- Keep bottles off the joints
Good ventilation is the best protection, and wipe the joints after use so mould struggles to take hold.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. An early reseal keeps water where it belongs.

Can I fix it myself?
You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
It’s tempting to reach for a kit, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Getting it right first time is generally cheaper.
How the visit works
We agree an arrival time beforehand. Once we are there, the work takes about two hours for a bath for most jobs. The room is left tidy and you will know when it can be used.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- 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 the area around the damage
- Tell us about parking, stairs or access
- Let us know if it has been repaired before
Getting a price
Getting a price is easy: take a close-up of the damage and a photo from further back, send them to us with your postcode, and we will reply with a fixed price. Quotes are free and no obligation.
