How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not wait for a small gap to become a leak
- Check trays and worktops don’t move
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Remedial sealant in Brightwalton, done properly
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. If you have smears and lumps from a botched reseal and beads that never stuck properly, we can put it right, on failed movement joints, botched or over-sealed joints and expansion joints alike.
Around Brightwalton, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
You get a 12-month guarantee, the same in Brightwalton as everywhere else we work.

How we quote for remedial sealant
We don’t publish a price list, because jobs vary so much. What we look at:
- The type of sealant required
- How many areas need sealing
- Whether there’s mould to deal with
- The size of the job
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Photos by email, if that is easy
- Where the property is
- How we’d reach the joints
- Any previous sealing or DIY work
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
Why it’s worth doing now in Brightwalton
Another bead over the top won’t fix a failed joint. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Around Brightwalton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

How it works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. For a village or hamlet like Brightwalton, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.

- Sealant in an older building that needs testing for asbestos first
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

Remedial sealant in Brightwalton: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
In the older streets around Church of All Saints, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as Brightwalton C.E. Aided Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

What the job involves on each surface
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal.
