Bath resealing in Dowlais Top without replacing anything
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. Our technicians work on wet rooms, kitchen worktops & sinks and basins & vanity units, and the jobs we see most are leaks at the edges and silicone coming away from the tiles.
Peace of mind is built in: our one-year guarantee applies to every job, and we’ll explain exactly what it covers when we quote.

FAQs for Dowlais Top
How long does silicone take to cure?
You’ll get the curing time from us, generally around a day.
What happens after I send pictures?
We review the pictures and send a fixed quote with dates.
Do I have to be there?
We need someone to let us in. You do not need to watch us work.
Can you redo someone else’s repair?
Yes, we frequently do. It can add a little time, which we include in the quote.
Is the work guaranteed?
All our work carries a one-year guarantee. Ask us what it covers when you get your quote.
How quickly can you book me in?
That depends on our diary for your area. We’ll offer you dates when we send your quote.
Is repairing better than replacing?
Usually, if the item is otherwise sound. A repair avoids removal and making good. If replacing would be better, we’ll say so.
Why does my sealant keep going mouldy?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
What affects the price in Dowlais Top
There are no hourly rates or hidden extras. The price is based on:
- The material
- How hard the colour is to match
- What kind of damage it is
- How easy the damage is to reach
The price depends on the type and amount of damage, what it’s made of and how many jobs we combine into one visit. You get a fixed quote from your pictures, so you know the cost before booking.
Quotes from your photos
We price nearly every job from pictures. This is what we need:
- A clear, close picture of the problem area
- A coin beside the damage so we can judge size
- Any earlier repairs or coatings
- Daylight if possible, and no flash reflection
Pricing is simple: take a close-up of the damage and a photo from further back, send them to us with your postcode, and you’ll get a fixed price back. Quotes are free and no obligation.
How to care for the repair
A little care keeps the finish looking good. We recommend:
- Open a window after bathing
- Dry the seal after bathing
- Give the seal a regular clean
- Run the extractor fan during and after showers
Avoid scraping the joints, and don’t stand bottles on the seal.
Don’t wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.

Honest limits
Some problems need a builder, plumber or fitter rather than us:
- Water damage behind the bath that needs a builder
- A bath or tray that moves, until its support is fixed
- Gaps too big for silicone alone
If in doubt, send photos and we will say what we think.
Materials we repair
- Shower trays & enclosures
- Wet rooms
- Kitchen worktops & sinks
- Baths
- Basins & vanity units
The process
There is not much you need to do on the day. Let us in and show us the room, and we will take it from there. The job generally runs to a couple of hours.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
How to prepare
- Have somewhere for us to park nearby if possible
- Mention if the room is upstairs or in a flat
- Make sure the room can be ventilated
How to get a price
For most jobs, pictures are all we need to give you a price. Add a line about what happened and your postcode, and we will send back a fixed quote and some dates.

Why it’s worth resealing in Dowlais Top
Sealing over old silicone is a false economy. It peels within weeks, and mould stays trapped behind it. We remove the old sealant completely. Every job is a little different, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.

Do you need bath resealing in Dowlais Top?
Sealant does not last forever. Each shower leaves moisture and soap behind, which mould loves, and the joint flexes each time the bath fills.
Customers typically contact us about:
- Missing sealant behind the taps
- A messy previous reseal

- Sealant that’s split or lifting

What your bath or shower is made of matters
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.

We fill the bath before sealing, to open the joint fully.
