Bath & shower resealing (mastic) in Y Fron, Gwynedd
We travel to Y Fron for bath, shower and sink resealing with new mould-resistant silicone. Nothing is taken out, and the work is guaranteed.

- An untidy old seal
About our bath resealing in Y Fron
A proper reseal starts with removing every trace of the old silicone. Fresh sealant doesn’t stick to old, which is why so many DIY reseals peel. If you are dealing with water getting behind the bath or tray and black spots in the silicone, we can help.
Big or small, it’s backed by a one-year guarantee in Y Fron and across Gwynedd.

What happens on the day
Visits start with a quick look at the job together. After that, protection goes down around the work area and the work begins. You can expect it to take a couple of hours.
- All the old sealant is cut out and removed.
- The joint is cleaned and any mould treated.
- We dry the joint thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, including around the taps.
Getting ready for the visit
- Clear the area around the damage
- Avoid using the area for a few hours before we arrive
- Mention any earlier repairs or resurfacing
How to get a price
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, include your postcode and send them over. What comes back is a fixed price, not a guess.

Can I fix it myself?
A DIY attempt is not a disaster. We take the old repair out and do it properly, so it doesn’t stop a professional repair. It does add a little time, so tell us about it when you send pictures.
We understand the appeal of fixing it 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.
Work for landlords and builders
If you manage property in Y Fron, we can repair and quote for several addresses together. Send pictures for each one and we will come back with a combined price.
Housing associations and facilities teams use us for planned and reactive repairs in Gwynedd and across the UK. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.
Honest limits
A repair isn’t always the answer, and we’d rather say so up front. We cannot fix:
- Rotten walls or floors behind the bath
- A bath or tray that moves, until its support is fixed
- Loose tiles, which need refixing first
Send us photos and we’ll tell you honestly.
Surfaces we repair
- Baths
- Shower trays & enclosures
- Wet rooms
- Kitchen worktops & sinks
- Basins & vanity units
Resealing in Y Fron: why it matters
Sealing over old silicone is a false economy. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. We do not add extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.
Why Y Fron customers choose us
- Usually one visit, start to finish
- Technicians who travel to you, UK-wide
- Dust sheets down, tidy finish
- Every repair guaranteed for a year

Common questions in Y Fron
Can you repair several things at once?
Yes. Doing several items on one visit usually costs less than separate visits. Include photos of each item.
Can landlords book you?
Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses.
Can you quote from pictures?
In nearly every case. If pictures do not show enough, we’ll ask for another angle.
Why does my sealant keep going mouldy?
Normally poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.
Is repairing better than replacing?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we’ll tell you.
Is there any odour?
There may be a mild smell during the work, which fades afterwards.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can new silicone go over old?
We always remove the old sealant completely. Fresh silicone does not stick to old.
Keeping it looking good
After the repair has cured, a few habits help it last:
- Keep bottles off the joints
- Reseal when black spots won’t clean off
- Use the extractor fan
- Air the room after use
Don’t scrape the sealant with anything sharp, and do not stand bottles on the seal.
Damp below or loose tiles need checking quickly. It may be more than a reseal, and we’ll say if you need a builder or plumber.
Repairs by material
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
