About our bath resealing in Pentrechwyth
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. If you are dealing with mould you can’t clean out and silicone coming away from the tiles, we can typically put it right, on wet rooms, basins & vanity units and baths alike.
All of our repairs are guaranteed for twelve months in Pentrechwyth and everywhere else. If something goes wrong with the work, we come back.

Aftercare tips
Most damage we see is avoidable. A few tips:
- Run the extractor fan during and after showers
- Give the seal a regular clean
- Air the room after use
- Store bottles on a shelf
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 affects the price in Pentrechwyth
A fixed quote means you know the cost before you book. We take into account:
- Doing more than one item at once
- Unusual colours or finishes
- Access to the area
- Previous DIY repairs that have to come out
Our prices are the same across the UK, with no extra for Pentrechwyth. The job itself decides the price: the material, the amount of damage and how many items.
How to get a fixed price
Phone pictures are fine, there’s no need for anything special. Just make sure we can see:
- Natural light rather than flash
- One picture of the entire bath or shower
- One sharp close-up of the damage
- Where you are, by postcode
For a price in Pentrechwyth, the easiest route is pictures: a close-up, a wider shot and your postcode. You’ll get a fixed quote with dates to choose from.
Your questions about bath resealing in Pentrechwyth
Can you do more than one item on the same visit?
Yes. Doing several items on one visit usually costs less than separate visits. Include pictures of each item.
Does someone need to be in?
Yes. We need access to the room while we work, at a time that suits you.
Can you reseal over the old silicone?
Never over old. It’s removed, cleaned off and the joint dried first.
Do you do work for letting agents?
We do, regularly. We quote for multiple addresses and fit around tenancy changeovers.
What happens next?
We review the pictures and send a fixed quote with dates.
Is it OK to have pets in the house?
Keep pets and children away from the work area on the day.
Are you accredited?
Yes, including CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Is a repair better than a new one?
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.
What we are called out for in Pentrechwyth
Poor ventilation speeds things up: damp hangs around, and mould grows faster.
Typical reasons for a call-out include:
- Stained silicone
- Mould you can’t clean out
- An untidy old seal
- Unsealed corners
What your quote should include
- What protection goes down before work starts
- The length of the guarantee and what it covers
- When it can be used again
- What prep work is covered
Work for landlords and builders
Housing associations and facilities teams use us for planned and reactive repairs. A repair avoids taking out and refitting, which is easier on the people living there.
Landlords, letting agents and housing providers in Pentrechwyth use us as well as householders. Repairing between tenancies keeps void periods short, and it usually costs far less than a refit.
How it works
There is not much you need to do on the day. Let us in and show us the room, and we will get on with it. The job generally runs to around two hours, tidy-up included.
- All the old sealant is cut out and removed.
- We clean the joint and treat any mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, taps included.
Preparing for the visit
- Make sure the room can be ventilated
- Mention if the room is upstairs or in a flat
- Clear toiletries, mats and anything else from around the area
How to get a price
To get a price, send a couple of photos through our quote form or call us. We’ll say straight away if a repair is the right fix.
Related advice
Should I try a DIY kit first?
Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is typically cheaper.
If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.
Why it’s worth resealing in Pentrechwyth
Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. A proper reseal removes the old first. Every job is a little different, so each one is priced on its own. The size and type of damage, the material and access all make a difference, and combining jobs on one visit brings the cost down.
