Remedial sealant for homes and businesses in Afton
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. Common call-outs are for caulk or the wrong sealant used in a wet area and sealant applied over old sealant that has lifted, on botched or over-sealed joints, failed movement joints and shrunken worktop sealant.
Around Afton, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
Our work is backed for twelve months, in Afton and everywhere else we cover.

Remedial sealant around Afton
Afton is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around St. Agnes' Church, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as All Saints Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Landlord and commercial work in Afton
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What the job involves on each surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned before backing and resealing.
FAQs for Afton
Is there a guarantee on remedial sealant in Afton?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Afton in your area for remedial sealant?
Yes. We work across London and the South East, and Afton is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
What if the leak is not the sealant?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Can you strip sealant from an acrylic tray safely?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
Looking after it afterwards
Aftercare is simple:
- Ask why a joint failed before redoing it
- Air the bathroom so the sealant can dry
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
Where we have pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
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. Each one is worth getting looked at.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Afton, access is often the only tricky part. 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.
Getting ready for the visit
- Clear the area around the work
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. In a small place like Afton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- A bath, tray or worktop that moves until it’s properly fixed
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
