For landlords and businesses
For anyone letting property in or around Llannerch-y-medd, we’ll quote for several properties at once. Just send photos for each address and we’ll come back with a combined price.
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 Llannerch-y-medd, done in place
We reseal baths with them filled with water, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. If you’re dealing with old sealant that looks dirty and gaps in the seal, we can help.
You’re covered for a year from the day of the repair. If anything isn’t right, ring us and we will sort it.

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.
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.
What bath resealing costs
Each job gets its own fixed price. This is what makes a difference:
- Previous DIY repairs that have to come out
- The type of damage
- The colour and finish to match
- How easy the damage is to reach
A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send pictures and you’ll get a fixed figure.
Getting a price from pictures
It only takes a minute to photograph the damage. Please include:
- The material, if you know it
- A wider photo showing the entire bath or shower
- Details of any past repairs
- Good light, ideally daylight, without flash glare
There is no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we will reply with a fixed price.
What your bath or shower is made of matters
Baths
Baths are resealed with water in them, so the joint is at its widest.

Common problems we fix in Llannerch-y-medd
Sealant does not last forever. Each shower leaves moisture and soap behind, which mould feeds on, and the joint flexes each time the bath fills.
Look out for these signs:
- A messy previous reseal
- Gaps in the seal
- Leaks at the edges
- Mould you can’t clean out

Llannerch-y-medd: your questions answered
When can I use the bath after resealing?
You’ll get the curing time from us.
My seal keeps tearing. Why?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
Can landlords book you?
Yes, frequently. We can quote for several properties together and work between tenancies.
Can I get a quote without a visit?
Typically, yes. A close-up and a wider photo are enough to give a fixed price.
Is there a call-out fee?
There’s no separate call-out charge. Your fixed quote includes everything.
What areas do you cover?
All of Isle of Anglesey, and the rest of the UK. Travel is included in the price.
How long will it take?
A bath or shower usually takes a couple of hours. Leave it to cure before use.
How quickly can you book me in?
Your quote comes with available dates. Tell us if you need it done quickly.
Keeping it looking good
It’s all simple stuff, just a few sensible habits:
- Ventilate the bathroom well
- Dry the seal after bathing
- Keep bottles off the joints
- Reseal when black spots will not clean off
Let it cure fully before using the bath or shower, normally about a day.
Black mould in sealant isn’t just unsightly, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.
What a repair cannot fix
To be straight with you, some problems need a different fix:
- Rotten walls or floors behind the bath
- Hollow or loose tiles
- Movement in the bath or tray
Send us photos and we’ll tell you honestly.
