Remedial sealant & repairs in Slaugham, West Sussex
Problem with your failed sealant joints in Slaugham? We cut out the old, prepare the joints and apply the right sealant.
- Decorators’ caulk around a bath or shower
- Smears and lumps from a botched reseal
- Mould trapped under a layer of silicone
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It generally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like Slaugham, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
How to prepare
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

Advice
How we handle remedial sealant in Slaugham
The wrong product in the wrong joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. If you have dark patches showing through the sealant and torn expansion joints, we can put it right.
Somewhere as small as Slaugham, 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.

Remedial sealant in Slaugham: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For landlords with property near Balcombe station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Warninglid Primary School are buildings too, and 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
Looking after new joints is easy:
- Keep an eye on the ceiling below the bathroom
- Report a tray that rocks or a worktop that lifts
- Don’t add new sealant on top of old
- Do not point over movement joints
Leave the new joint to cure fully before it gets wet or moves: normally around 24 hours, or as long as we advise.
Signs to act on: 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.
Different surfaces, different methods
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Do you need remedial sealant in Slaugham?
Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints split any bead that’s too stiff or too thin.
If you can see any of these, it’s time to have the joints looked at:
- Decorators’ caulk around a bath or shower
- Black mould underneath the bead
- Repeat leaks from the same joint
- Gaps opening along the back of the worktop
If you live in an older home near St Mary's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
