About our remedial sealant in Slade Green
In Slade Green, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We are often asked to deal with smears and lumps from a botched reseal and sealant peeling off a dusty or damp surface, on expansion joints, shrunken worktop sealant and failed movement joints.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Slade Green more than a cosmetic job.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Should I try it myself first?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. In Slade Green, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

Common problems we fix in Slade Green
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
Any of these means the joints need attention:
- Leaks that keep coming back after resealing
- Dark patches showing through the sealant
- Decorators’ caulk around a bath or shower
- Beads that never stuck properly
Slade Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What to look for in a quote
- How the surfaces are prepared before sealing
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
- What insurance they hold
Keeping the joints in good condition
After the cure time, these simple habits help:
- Report a tray that rocks or a worktop that lifts
- Do not wait for a small gap to become a leak
- Always have old sealant cut out, not covered
- Do not point over movement joints
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
How we quote for remedial sealant
We don’t publish a price list, because no two jobs are the same. What we look at:
- When we can work, for business premises
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- The type of property
- The problem you’ve noticed
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
Remedial sealant in Slade Green: local notes
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.
Rented homes near Slade Green station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. In the older streets around St. Augustine's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Questions from Slade Green
I live in a flat in Slade Green. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up 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 Slade Green?
Parking in Slade Green, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Is remedial work guaranteed?
Yes, with our one-year guarantee. If we have pointed out another problem, getting it fixed helps the new joint last.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
