Looking after it afterwards
How the surface is treated afterwards matters. Here’s what we suggest:
- Reseal when black spots won’t clean off
- Open a window after bathing
- Wipe the joints dry after use
- Use the extractor fan
Run the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, and we’ll say if you need a builder or plumber.
The process
On the day itself, there’s little for you to do. Let us in and show us the room, and we’ll get on with it. The job generally runs to a couple of hours.
- We cut out and remove all of the old sealant.
- Next we clean the joint and deal with mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, taps included.
Before we arrive
- Let the surface dry out before the visit
- Keep a parking space free if you can
- Open a window if you can

Questions from Rhosgadfan
Will the price change on the day?
The price is fixed for what the pictures show. If there is more, we will tell you before starting.
Are there extra charges for Rhosgadfan?
There’s no separate call-out charge. The fixed price covers the visit and the work.
How long does silicone take to cure?
You will get the curing time from us.
Can pets and children be at home?
Just keep them out of the work area. We’ll let you know when it’s safe to use again.
How long does resealing take?
A bath or shower usually takes a couple of hours. Leave it to cure before use.
How soon can you come?
It depends on the time of year and where you are. Send pictures with your postcode and we will reply with the earliest dates.
It’s been repaired before. Can you still fix it?
Yes, regularly. It can add a little time, which we include in the quote.
Is repairing better than replacing?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. We will be honest if it’s not worth it.

Can I fix it myself?
If you’ve already tried a DIY fix, that is fine. We remove the old filler and start again, so it won’t stop us repairing it. It does add a little time, so tell us about it when you send photos.
If you do try a kit, read the instructions carefully, make sure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.
What bath resealing costs
You will not pay by the hour. The price is based on:
- The size and number of damaged areas
- Whether it’s a chip, crack, burn or wear
- The material and finish
- Whether old repairs or coatings need taking off
Set against the cost of replacement, a repair is usually a fraction of the price, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.
Quotes from your pictures
Before you send pictures, a few simple things make all the difference:
- Any earlier repairs or coatings
- Something in shot to show the size
- The postcode, so we can plan the visit
- The material, if you know it
Most clients in Rhosgadfan get their price from photos. Add a line about what happened and your postcode, and we will send back a fixed quote and some dates.
