About our bath resealing in Croespenmaen
Baths are resealed with water in them, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. Typical jobs include gaps in the seal and missing sealant behind the taps, in shower trays & enclosures, kitchen worktops & sinks and wet rooms.
All of our repairs are guaranteed for twelve months. If something goes wrong with the work, we come back.

What we do, step by step
From the moment we arrive, we keep the work contained to the one room. Surfaces nearby are masked off, the work takes around two hours, depending on what we find, and we finish with a tidy-up and a look at the finished work together.
- We cut out and remove all of the old sealant.
- The joint is cleaned and any mould treated.
- We dry the joint thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
How to prepare
- Make sure the area is dry
- Tell us about any previous repairs or coatings
- Open a window if you can

Landlord and trade work in Croespenmaen
We work for landlords, letting agents and housing providers in Croespenmaen as well as householders. A repair between tenants keeps the property empty for less time, and it normally costs far less than a refit.
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.
Materials and what they mean for the repair
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Baths
We fill the bath before sealing, to open the joint fully.

Do you need bath resealing in Croespenmaen?
Black mould is the most common reason people reseal. It grows into the silicone, so cleaning only removes the surface.
Keep an eye out for any of the following:
- Leaks at the edges
- Missing sealant behind the taps
- Mould you can’t clean out
- An untidy old seal

How we price bath resealing
You will not pay by the hour. The price depends on:
- Access to the area
- How much damage there is
- How hard the colour is to match
- Doing more than one item at once
There are no surprise extras on the day. The price we quote from your pictures is the price you pay, unless the damage turns out to be different, in which case we talk to you first.
Quotes from your photos
When you take your photos, these tips help us give you a firm price:
- Where you are, by postcode
- A close-up of the damage, in focus
- The material, if you know it
- Good light, ideally daylight, without flash glare
The quickest way to a price is to send a couple of pictures through our quote form or ring us. We will say straight away if a repair is the right fix.
Aftercare tips
After the repair has cured, a few habits help it last:
- Wipe the joints dry after use
- Clean the joints with a mild cleaner
- Ventilate the bathroom well
- Air the room after use
Leave the sealant to cure for the time we give you, normally about a day.
Damp below or loose tiles need checking quickly. It may be more than a reseal, and we will say if you need a builder or plumber.
Why it’s worth resealing in Croespenmaen
Resealing costs very little, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. Compared with replacing, a repair is generally a fraction of the price, because there is no removal, plumbing or making good. The quote lists exactly what you are paying for.
