Landlords, agents and businesses in Onllwyn
We carry out planned and one-off repairs for housing associations and facilities teams in Neath Port Talbot and across the UK. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.
Rented homes see more wear and tear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.
Bath resealing in Onllwyn without replacing anything
A reseal is a small job that makes a big difference. Clean, white joints make a bathroom look cared for, and they protect the walls and floor. Whether it’s unsealed corners and mould you can’t clean out, we can typically put it right, whatever the material.
You’re covered after we leave: each job carries a one-year guarantee, and we explain what it covers before booking.

How it works
We agree an arrival time beforehand, so you are not left guessing. Once we are there, the work takes a couple of hours in most cases. The room is left tidy.
- All the old sealant is cut out and removed.
- The joint is cleaned and any mould treated.
- We dry the joint thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, taps included.
How to prepare
- Mention any parking restrictions or tricky access
- Make sure the area is dry
- Mention any earlier repairs or resurfacing
Ask for a price
Pricing is simple: take a close-up of the damage and a photo from further back, send them to us with your postcode, and you’ll get a fixed price back. Quotes are free and no obligation.

Prices and what affects them
There is no charge for travel to Onllwyn. The price depends on:
- How easy the damage is to reach
- Whether we combine several jobs
- Previous DIY repairs that have to come out
- The material and finish
We don’t add extras on the day. What we quote from your pictures is what you pay, and if the damage turns out to be different, we discuss it before starting.
Quotes from your pictures
You can typically get a fixed price without us visiting. To make it quick:
- Whether it’s been repaired or coated before
- A clear, close picture of the problem area
- Daylight if possible, and no flash reflection
- A wider photo showing the whole bath or shower
Ring 0345 017 0787, or send us photos through the quote form. With a clear picture of the damage and one of the whole bath or shower, we can give you a fixed quote without visiting.
What we cannot put right
We will not take on work that won’t last, so these are the limits:
- Hidden water damage

- Loose tiles, which need refixing first

Is resealing worth it?
Resealing is a small job. Leaving split or mouldy sealant lets water get behind the bath or tray, and that damage costs much more to fix. Rather than charging by the hour, we price the entire job up front. Damage, material and access decide it, and combining items on one visit brings it down.
Why us?
- Honest advice, even when it means no job
- One price list for the entire UK
- Fixed prices from your photos
- Repair technicians who travel to you, UK-wide

Should I try a DIY kit first?
It’s tempting to reach for a kit, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is generally the cheaper route.
It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.

Common questions in Onllwyn
Why does the silicone keep cracking?
Something is moving. If it keeps happening, the support may need fixing.
Do you work in Onllwyn?
We do. Technicians travel to Onllwyn from across the region, and the price is the same as everywhere else.
Can I get a quote without a visit?
In nearly every case. If photos do not show enough, we will ask for another angle.
When can I use the bath after resealing?
You’ll get the curing time from us, generally around a day.
It’s been repaired before. Can you still fix it?
Yes, regularly. It can add a little time, which we include in the quote.
When can you do it?
Your quote comes with available dates. If it’s urgent, say so and we’ll do what we can.
How long does resealing take?
Most reseals take about two hours. It then needs time to cure.
Do you charge for travel?

Materials and what they mean for the repair
Baths
We fill the bath before sealing, to open the joint fully.
Shower trays
Trays are sealed with weight on them, for the same reason.
Looking after it afterwards
Good habits make a big difference to how long a repair lasts. Here’s what we suggest:
- Let steam out after showers
- Clean the joints with a mild cleaner
- Reseal at the first sign of lifting
- Run the extractor fan during and after showers
Good ventilation is the best protection, and dry the joints after bathing to keep mould away.
Black mould in sealant is not just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
