What the job involves on each surface

Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
Remedial sealant in Westwell, done properly
Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. Typical jobs include repeat leaks from the same joint and worktop sealant that has shrunk and split, across mouldy bath & shower sealant, shrunken worktop sealant and leaking tray & enclosure joints.
Somewhere as small as Westwell, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Every job is covered by a 12-month guarantee.

Aftercare tips
Looking after new joints is easy:
- Ask why a joint failed before redoing it
- Always have old sealant cut out, not covered
- Don’t point over movement joints
- Use a soft cloth, not a scourer, on silicone
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.

The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the amount of work. For a village or hamlet like Westwell, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can

Advice
Common problems we fix in Westwell
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing sets the depth and stops that.
Common reasons people contact us include:
- Kitchen joints letting water behind the worktop
- Sealant peeling off a dusty or damp surface
- Movement joints that have split or pulled away
- Black mould underneath the bead
If you live in an older home near Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant.

Remedial sealant in Westwell: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as The Hayesbrook School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Charing station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why act early in Westwell
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing usually puts it right. Where something else has failed, you’ll hear it from us. Older cottages and farmhouses around Westwell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.
