East Ashling Remedial Sealant
Our applicators work in East Ashling on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Products that weren’t meant for the joint
- Sealant peeling off a dusty or damp surface
- Dark patches showing through the sealant
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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.
About our remedial sealant in East Ashling
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. We are often asked to deal with repeat leaks from the same joint and movement joints that have split or pulled away, across shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints.
Homes around East Ashling are mostly houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
Whatever the size of the job, it’s backed by our 12-month guarantee in East Ashling and across West Sussex.

Looking after it afterwards
To keep the joints looking good and working properly:
- Keep movement joints clear of mortar and paint
- Keep the room well ventilated
- Check trays and worktops don’t move
- Always have old sealant cut out, not covered
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.

Remedial sealant around East Ashling
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 Funtington Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of St Andrew, walls and floors in older homes can move, and sealant and grout show it first. Rented homes near Bosham station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

What else we do in East Ashling
How it works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours, depending on how many layers have to come out. Somewhere as small as East Ashling, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

East Ashling: your questions answered
Can you do remedial sealant in East Ashling?
Yes. We work across London and the South East, and East Ashling is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Bosham station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Are you fully insured?
Yes. Full insurance covers our work.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Why deal with it now?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Where a wall is exposed, as many are in small places like East Ashling, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
