- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.

Advice
How we handle remedial sealant in Crosspost
Some sealant jobs aren’t 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 before the joint can be done properly. We are often asked to deal with floor or wall movement joints that have failed and sealant that came away because the surface wasn’t prepared, across mouldy bath & shower sealant, shrunken worktop sealant and failed movement joints.
For a small place like Crosspost, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Surface by surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before any new sealant goes on.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces.
Landlords, agents and businesses in Crosspost
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Movement from fittings that are not supported
- Failed tanking or loose tiles behind the sealant
- Plumbing leaks behind walls or under trays
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal

Crosspost questions
I let a flat near Wivelsfield station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you work in hotels near Crosspost?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How much does remedial sealant cost in Crosspost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours.
Can you fix a reseal that hasn’t worked?
Yes, usually. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When to call us in Crosspost
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Look out for any of the following:
- Movement joints that have split or pulled away
- Smears and lumps from a botched reseal
- Black mould underneath the bead
- Worktop sealant that has shrunk and split
In the older streets around St Mary Magdalene's Church, walls and floors in older homes can move, and sealant and grout show it first.

What remedial sealant looks like in Crosspost
Crosspost has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Schools such as Bolney CofE 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. Letting a property close to Wivelsfield station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep an eye on the ceiling below the bathroom
- Deal with small splits early
- Never seal over old silicone
- Use a soft cloth, not a scourer, on silicone
Don’t let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
