About our bath resealing in Rhydyfelin
A proper reseal starts with removing every trace of the old silicone. New silicone will not bond to old, which is why many DIY jobs peel. We’re frequently asked to fix water getting behind the bath or tray and unsealed corners, in kitchen worktops & sinks, baths and wet rooms.
You are covered after we leave: our one-year guarantee applies to every job, and we will explain exactly what it covers when we quote.

Common questions in Rhydyfelin
What information do you need?
Just pictures, your postcode and a contact number. On the day, we only need access to the room.
Which areas do you work in?
We cover the entire UK, including Rhydyfelin and the rest of Rhondda Cynon Taff. Send your postcode with your photos and we will confirm dates.
Do you cover Rhydyfelin?
Yes. We work across the UK and travel to Rhydyfelin and the rest of Rhondda Cynon Taff. Send us pictures for a fixed quote, or call 0345 017 0787.
Can you repair something that is been repaired before?
Most of the time. Tell us what was done before.
Can you price it without visiting?
In nearly every case. If photos do not show enough, we’ll ask for another angle.
Do you do work for letting agents?
Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses in Rhydyfelin.
Is there a call-out fee?
There is no separate call-out charge. Your fixed quote includes everything.
Why does mould come back so fast?
Typically poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.
How we price bath resealing
Each job gets its own fixed quote. These are the things that affect it:
- Previous DIY repairs that have to come out
- How many items we do on one visit
- The colour and finish to match
- How easy the damage is to reach
No two jobs are quite the same, so each one is priced on its own. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.
Quotes from your pictures
When you take your photos, these tips help us give you a firm price:
- Daylight if possible, and no flash reflection
- A coin or ruler next to the damage for scale
- The postcode, so we can plan the visit
- Any details about the material
For most jobs, photos are all we need to give you a price. Tell us what happened and where you are, and we will send back a fixed quote and some dates.

DIY kit or professional repair?
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 normally cheaper.
A DIY attempt isn’t a disaster. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send pictures, as it can add time.
Repairs by material
Shower trays
We put weight on a tray before sealing it, for the same reason.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Common problems we fix in Rhydyfelin
No sealant lasts for ever. Each shower leaves moisture and soap behind, which mould loves, and the joint flexes each time the bath fills.
Contact us if you’ve noticed:
- Discoloured, yellow sealant
- Leaks at the edges
- Silicone coming away from the tiles
- Silicone smeared on tiles
Questions to ask before booking
- How changes to the job are handled
- What aftercare is recommended
- Whether the price covers travel
- Whether the price is fixed and includes VAT
When a repair is not the answer
We’d rather lose a job than do one that will not last, so these are the limits:
- Water damage behind the bath that needs a builder
- Tiles that move, until they’re refixed
- Gaps too big for silicone alone
Send us photos and we’ll tell you honestly.
Surfaces we repair
- Kitchen worktops & sinks
- Baths
- Wet rooms
- Shower trays & enclosures
- Basins & vanity units
The process
When we visit, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. Expect it to take around two hours. We clean up when we are done and tell you when it’s ready to use.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- The bath is filled with water, or weight put on the tray.
- We apply fresh mould-resistant silicone and tool a neat bead.
Getting ready for the visit
- Make sure the room can be ventilated
- Clear toiletries, mats and anything else from around the area
- Avoid using the area for a few hours before we arrive
Getting a price
No survey visit is needed: we price from photos. Use the quote form, or ring 0345 017 0787 to talk it through, and we will come back with a fixed figure.

Looking after it afterwards
A little care keeps the finish looking good. Our advice:
- Clean the sealant gently and regularly
- Do not stand toiletries on the seal
- Replace the seal when mould sets in
- Air the room after use
Run the extractor fan, dry the joints after bathing, and give them a regular clean with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem. An early reseal keeps water where it belongs.
Is resealing worth it?
Compared with repairing water damage, resealing is cheap. It’s a quick job that protects your walls and floors. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send photos and you will get a fixed figure.
