About our remedial sealant in Cookham Dean
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that’s what we find, we’ll tell you rather than reseal something that won’t fix it. If you’re dealing with movement joints that have split or pulled away and thick, messy sealant smeared over tiles, we can help, on failed movement joints, leaking tray & enclosure joints and mouldy bath & shower sealant alike.
For a small place like Cookham Dean, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
All of our work is guaranteed for twelve months.

Looking after it afterwards
Aftercare is simple:
- Ask why a joint failed before redoing it
- Air the bathroom so the sealant can dry
- Have loose fittings fixed before resealing
- Don’t point over movement joints
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just call 0345 464 0079 or send us an email.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
When something else is needed
We will always be straight with you, so here’s what sealant cannot fix:
- A cracked shower tray or bath (that needs repair or replacing)
- Failed tanking or loose tiles behind the sealant
- A leaking trap, valve or supply pipe
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
What happens if it’s left?
Another bead over the top will not fix a failed joint. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Cookham Dean can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.

What we are called out for in Cookham Dean
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints split any bead that is too stiff or too thin.
Any of these means the joints need attention:
- Worktop sealant that has shrunk and split
- Mould trapped under a layer of silicone
- Movement joints that have split or pulled away
- Leaks that keep coming back after resealing
For an older house near a landmark such as Church of St John the Baptist, older homes can move a little, which is hard on rigid grout and tired sealant.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like Cookham Dean, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
