Resealing in Coed-mawr: why it matters
Resealing is a small job. Putting off a reseal lets water get behind the bath or tray, and that damage costs much more to fix. 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 play a part, and doing several things on one visit costs less than separate visits.
Why book with us
- No need to remove anything
- Dust sheets down, tidy finish
- One-year guarantee on every repair
- Free fixed quotes from pictures

How we handle bath resealing in Coed-mawr
A proper reseal starts with removing every trace of the old silicone. Fresh sealant doesn’t stick to old, which is why many DIY jobs peel. Whether it’s leaks at the edges and a messy previous reseal, we can help.
You get a one-year guarantee, the same in Coed-mawr as everywhere else we work.

How it works
When we visit, we arrive at the time we have agreed, cover the area with dust sheets and masking, and set to work. Expect it to take a couple of hours. We tidy up before we leave and tell you when it’s ready to use.
- We cut out and remove all of the old sealant.
- We clean the joint and treat any mould.
- We dry the joint 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.
Getting ready for the visit
- Tell us if there are stairs or a lift
- Keep a parking space free if you can
- Open a window if you can
How to get a price
A quote takes minutes to ask for: photograph the damage, then the whole bath or shower, add your postcode and send them to us. You’ll get a fixed price, not an estimate.

What your bath or shower is made of matters
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Looking after it afterwards
Nothing complicated is needed, just a few sensible habits:
- Clean the sealant gently and regularly
- Use the extractor fan
- Store bottles on a shelf
- Replace the seal when mould sets in
Don’t scrape the sealant with anything sharp, and don’t stand bottles on the seal.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. An early reseal keeps water where it belongs.
Should I try a DIY kit first?
It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and the old filler has to come out before a proper repair.
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.

Prices and what affects them
We give every job a fixed quote from pictures. These are the things that affect it:
- How many areas need work
- What kind of damage it is
- How many items we do on one visit
- Whether old repairs or coatings need taking off
A repair is priced on what needs doing, not where you live. You’ll see the full price before booking, with nothing added on the day.
Getting a price from pictures
Photographing the damage takes a minute, and it saves a visit. Please include:
- A coin beside the damage so we can judge size
- Daylight if possible, and no flash reflection
- The material, if you know it
- One picture of the whole bath or shower
Send us photos of the damage and one of the entire item, and tell us you’re in Coed-mawr, and we will reply with a fixed price.
When to call us in Coed-mawr
Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.
If you can see any of these, send us a photo:
- Gaps by the taps
- Water getting behind the bath or tray
- Mould you can’t clean out
- Silicone smeared on tiles
Before you book anyone
