FAQs for Pen-twyn
What if the damage is worse than the pictures show?
Your quote covers the damage in the photos. If there’s more, we’ll tell you before starting.
Is a repair better than a new one?
Generally, when the rest is in good condition. A repair avoids removal and making good. If replacing would be better, we will say so.
Is there a call-out fee?
No. Our quotes include travel, with the same prices everywhere we work.
Why does my sealant keep splitting?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
Do you do work for letting agents?
Yes. We work for landlords, agents, builders and businesses as well as householders across Monmouthshire.
How long does silicone take to cure?
You’ll get the curing time from us.
Do you seal over the old sealant?
We always remove the old sealant completely. Fresh silicone doesn’t stick to old.
What information do you need?
Some pictures, your postcode and how to reach you. On the day, access to the room.
Bath resealing in Pen-twyn without replacing anything
The key to a good reseal is getting all of the old silicone out. Fresh sealant doesn’t stick to old, which is why many DIY jobs peel. Common call-outs are for unsealed corners and damp near the bath, on baths, kitchen worktops & sinks and shower trays & enclosures.
You get a one-year guarantee, the same in Pen-twyn as everywhere else we work.

What else we do in Pen-twyn
How to look after the repair
Much of the damage we repair could have been avoided. A few tips:
- Reseal at the first sign of lifting
- Clean the joints with a mild cleaner
- Do not stand toiletries on the seal
- Run the extractor fan during and after showers
Avoid scraping the joints, and keep shampoo bottles off the joints.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.
Should I try a DIY kit first?
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
Kits are cheap and easy to find, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Getting it right first time is normally cheaper.
When we would advise against a repair
We would rather lose a job than do one that won’t last, so here’s what a repair can’t put right:
- Gaps too big for silicone alone
- Hidden water damage
- Tiles that move, until they’re refixed
Send us pictures and we will tell you honestly before you book.
Surfaces we repair
- Shower trays & enclosures
- Kitchen worktops & sinks
- Basins & vanity units
- Baths
- Wet rooms
Landlords, agents and businesses in Pen-twyn
Hotels, guest houses and holiday lets cannot afford rooms out of action for long, so most of our work is done in a single visit. We will fit around changeovers where we can.
We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover so nothing needs replacing. We hold CHAS, Constructionline and SafeContractor accreditations.
What we are called out for in Pen-twyn
Even good sealant eventually discolours particularly in a well-used bathroom. Steam, soap and movement all wear it down.
You may need us if you’ve spotted:
- Water getting behind the bath or tray
- Stained silicone
- Silicone coming away from the tiles
- Mould you can’t clean out

Materials and what they mean for the repair
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Baths
Baths are resealed with water in them, to open the joint fully.
How it works
On the day, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. The job normally takes a couple of hours. We tidy up before we leave and let you know when you can use it again.
- We protect the area and mask the joint lines.
- We remove the old sealant and every trace of residue.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- We smooth the bead, remove the tape and leave it to cure.
How to prepare
- Clear the area around the damage
- Keep a parking space free if you can
- Make sure the area is dry
Getting a price
A quote takes minutes to ask for: photograph the damage, then the whole bath or shower, add your postcode and send them over. You will get a fixed quote, not an estimate.
Advice
Why reseal now?
Resealing costs very little and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. Instead of hourly rates, we fix the price before we start. It depends on the damage, the material and access.
Why us?
- Nothing taken out or refitted
- CHAS, Constructionline and SafeContractor accredited
- Dust sheets down, tidy finish
- Generally one visit, start to finish
