Bath & shower resealing (mastic) in Treorchy, Rhondda Cynon Taff

- Discoloured, yellow sealant
- Sealant that’s split or lifting
- Silicone smeared on tiles
Why it’s worth resealing in Treorchy
Resealing is routine maintenance. Leaving split or mouldy sealant lets water get behind the bath or tray, which costs far more to put right. A few things move the price: access, material, the extent of the damage and whether we can do several items together. Send pictures and you’ll get a fixed figure.

Bath resealing in Treorchy, done in place
Baths are resealed with water in them, so the joint opens fully, so the seal doesn’t tear when the bath is first used. Our technicians work on baths, wet rooms and shower trays & enclosures, and people most often call us about sealant that’s split or lifting and stained silicone.

When we’d advise against a repair
Some problems need a builder, plumber or fitter rather than us:
- Loose tiles, which need refixing first

- Hidden water damage
Send us photos and we’ll tell you honestly.

Different materials, different repairs
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Landlord and trade work in Treorchy
Hotels, guest houses and holiday lets cannot afford rooms out of action for long, so most of our work is done in a single visit. We will fit around changeovers where we can.
Letting agents frequently send us photos straight from the inventory. You can have a price before you arrange access, and we liaise with tenants about access if you’d like us to.
Should I try a DIY kit first?
If you are set on a kit, follow its instructions closely and work on a clean, dry surface, and don’t use it until it has fully cured. If it fails, we can still put it right.
You can buy a DIY kit for most repairs, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.

Aftercare tips
Much of the damage we repair could have been avoided. These habits help:
- Keep bottles off the joints
- Ventilate the bathroom well
- Keep the joints dry
- Air the room after use
Avoid scraping the joints, and keep shampoo bottles off the joints.
Mouldy sealant is more than a cosmetic problem, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.
Treorchy: your questions answered
Can new silicone go over old?
We always remove the old sealant completely. Fresh silicone does not stick to old.
How long does a reseal take?
Around two hours for a bath, then it needs to cure.
How soon can you come?
That depends on our diary for your area. Send photos with your postcode and we’ll reply with the earliest dates.
How long before I can shower?
Normally about a day later. We’ll tell you the exact time.
Is it OK to have pets in the house?
We ask you to keep children and pets out of the room while we work and until it has cured. The rest of the house is unaffected.
How do I book?
Photos of the damage, a picture of the entire bath or shower and your postcode. After that, we just agree a date.
Are there extra charges for Treorchy?
Travel is included in the price, with the same prices everywhere we work.
