Remedial sealant in Radfall
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. We work on expansion joints, botched or over-sealed joints and failed movement joints, and people most often call us about black mould underneath the bead and thick, messy sealant smeared over tiles.
In a village or hamlet like Radfall, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
All of our work is guaranteed for twelve months.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Check ceilings under showers for marks
- Clean sealant with mild products only
- Run the fan after every shower
- Report a tray that rocks or a worktop that lifts
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, call 0345 464 0079 or email us.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Early action keeps it to a sealant job.
FAQs for Radfall
Do you work for landlords with property near Chestfield & Swalecliffe station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Radfall in your area for remedial sealant?
Yes, Radfall is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Can you fix a reseal that hasn’t worked?
Yes. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Does remedial work come with a guarantee?
Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.
Do you fix expansion and movement joints?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What affects the cost of remedial sealant
The price is agreed before any work begins. It takes into account:
- Any working-time requirements on site
- How much there is to do
- How many rooms, windows or areas are involved
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Whether it’s a home or a business
- Where the property is
- A few photos by email, if you can
- If someone has resealed it before
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Should I try it myself first?
If you’re set on DIY, put the effort into 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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens if it’s left?
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you’ll hear it from us. Older cottages and farmhouses around Radfall can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

Radfall homes and their sealant
Radfall is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. 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.
If you look after a building such as The Whitstable School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Radfall, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Keep children and pets away from the work area

Related advice
Common problems we fix in Radfall
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing sets the depth and stops that.
Look out for any of the following:
- Black mould underneath the bead
- Caulk or the wrong sealant used in a wet area
- Sealant that came away because the surface wasn’t prepared
- Smears and lumps from a botched reseal
Rented homes near Chestfield & Swalecliffe station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
