Remedial sealant for St Mary in the Marsh and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Wide, uneven beads that look worse than the old ones
- Movement joints that have split or pulled away
- Worktop sealant that has shrunk and split
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Deal with small splits early
- Air the bathroom so the sealant can dry
- Report a tray that rocks or a worktop that lifts
- Check ceilings under showers for marks
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
About our remedial sealant in St Mary in the Marsh
Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. Common call-outs are for mould trapped under a layer of silicone and movement joints that have split or pulled away, on expansion joints, failed movement joints and leaking tray & enclosure joints.
In a village or hamlet like St Mary in the Marsh, 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.
There’s a 12-month guarantee on every job, whatever its size.

When to call us in St Mary in the Marsh
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Any of these means the joints need attention:
- Repeat leaks from the same joint
- Sealant that came away because the surface wasn’t prepared
- Mould trapped under a layer of silicone
- Movement joints that have split or pulled away
Managing a site like The Marsh Academy? Then 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.
What to look for in a quote

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Bathrooms and kitchens in St Mary in the Marsh
St Mary in the Marsh 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, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to Church of St Mary the Virgin include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as St Mary in the Marsh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

- Access and height
- The number of rooms or windows

- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- Photos by email, if that’s easy

FAQs for St Mary in the Marsh
Will you come out to St Mary in the Marsh?
Yes, St Mary in the Marsh is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with remedial sealant in St Mary in the Marsh?
All our work, in St Mary in the Marsh and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What if the leak is not the sealant?
That’s why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- A cracked shower tray or bath (that needs repair or replacing)
- A tray or worktop that needs refixing first
- Water damage behind tiles that needs a tiler
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
