Clay Hill Remedial Sealant

- Repeat leaks from the same joint

Remedial sealant in Clay Hill, done properly
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. We work on expansion joints, botched or over-sealed joints and mouldy bath & shower sealant, and people most often call us about dark patches showing through the sealant and gaps opening along the back of the worktop.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
A one-year guarantee comes as standard.

Questions from Clay Hill
Can worn sealant in a flat in Clay Hill cause a leak downstairs?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Is parking a problem for a job in Clay Hill?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Does remedial work come with a guarantee?
Yes, for 12 months. Where we’ve flagged another fault, it needs fixing for the joint to last.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Can you strip sealant from an acrylic tray safely?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Why deal with it now?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out, so the joint can be treated and resealed. In a flat in Clay Hill, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Bathrooms and kitchens in Clay Hill
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London’s water is hard, so limescale builds up on sealant, grout and fittings.
Clay Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Gordon Hill station, botched sealant from a previous quick fix is easier to strip out between tenants.

When to call us in Clay Hill
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
Look out for these signs:
- Floor or wall movement joints that have failed
- Wide, uneven beads that look worse than the old ones
- A shower that leaks however often it’s resealed
- Beads that never stuck properly
If you live in an older home near Church of St John the Baptist, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What the job involves on each surface
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, 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.
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job usually takes a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work

Advice
When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A cracked shower tray or bath (that needs repair or replacing)
- Movement from fittings that are not supported
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
