About our bath resealing in Bryn-y-waen
Resealing is quick, but it transforms the look. Fresh joints make the entire room look cleaner, and they keep water out. We regularly repair kitchen worktops & sinks, basins & vanity units and wet rooms, and people most often call us about an untidy old seal and water getting behind the bath or tray.
Every job is backed for twelve months in Bryn-y-waen and everywhere else. If something goes wrong with the work, we come back.

How to look after the repair
Once the work has cured, treat it gently:
- Store bottles on a shelf
- Clean the joints with a mild cleaner
- Run the extractor fan during and after showers
- Air the room after use
Let it cure fully before using the bath or shower, generally around 24 hours.
Damp below or loose tiles need checking quickly. There may be more going on, so we will tell you if it needs a builder or plumber.
Why it’s worth resealing in Bryn-y-waen
Resealing costs very little, and it protects everything around the bath. Failed sealant can lead to water damage that is much more expensive. Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send pictures and we will give you the exact figure.

How it works
Visits start with a quick look at the job together. Then the area is sheeted and masked and we start. It normally takes a couple of hours.
- We cut out all of the old sealant.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- 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

- Tell us about any previous repairs or coatings
- Let us know which floor the room is on
