- Mouldy bath & shower sealant
- Failed movement joints
- Expansion joints
How we handle remedial sealant in Picket Twenty
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have leaks that keep coming back after resealing and beads that never stuck properly, we can help.
In a village or hamlet like Picket Twenty, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Different surfaces, different methods
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal in a colour to suit.
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What we are called out for in Picket Twenty
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
Most people get in touch when they notice something like this:
- Black mould underneath the bead
- A shower that leaks however often it’s resealed
- Decorators’ caulk around a bath or shower
- Sealant peeling off a dusty or damp surface
Managing a site like Pilgrims' Cross CofE Aided Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Air the bathroom so the sealant can dry
- Clean sealant with mild products only
- Find out why the sealant failed first
- Never seal over old silicone
Keep the room ventilated: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
