West Barnes Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for householders, landlords and businesses in West Barnes. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Products that weren’t meant for the joint
- Smears and lumps from a botched reseal
- Leaks that keep coming back after resealing
How to look after the new joints
So the new joints stay in good condition:
- Clean sealant with mild products only
- Run the fan after every shower
- Do not add new sealant on top of old
- Check trays and worktops do not move
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
Remedial sealant for homes and businesses in West Barnes
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are ARBOMaster approved and fully insured, and remedial work carries our one-year guarantee. Typical jobs include movement joints that have split or pulled away and sealant that came away because the surface wasn’t prepared, on botched or over-sealed joints, mouldy bath & shower sealant and shrunken worktop sealant.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in West Barnes are no different.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When it is not the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Tiles that have come away from the wall
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Landlord and commercial work in West Barnes
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
We also work for property managers and facilities teams in West Barnes and across Greater London. We can quote a run of properties together.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes a few hours for most joints, depending on how much old sealant has to come out. For a job in West Barnes, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Let us know about parking restrictions
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

Why act early in West Barnes
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in West Barnes.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What you get with us
- A 12-month guarantee on all work
- An ARBOMaster approved applicator
- We are fully insured
- We agree the colour with you first

How the job changes by surface
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, which we’ll point out.
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Your questions about remedial sealant in West Barnes
Do you work for landlords with property near Motspur Park station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is parking an issue for remedial sealant in West Barnes?
Parking in West Barnes, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you guarantee remedial jobs?
Yes, for 12 months. Where we’ve flagged another fault, it needs fixing for the joint to last.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
Do you cover West Barnes?
Yes. We work in West Barnes. For a quote, call 0345 464 0079 or email us.
Signs you need remedial sealant in West Barnes
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. Then the only fix is removal and a new bead.
Keep an eye out for any of the following:
- Wide, uneven beads that look worse than the old ones
- Worktop sealant that has shrunk and split
- Leaks that keep coming back after resealing
- Sealant peeling off a dusty or damp surface
If you let a flat or house near Motspur Park station, botched sealant from a previous quick fix is easier to strip out between tenants.

What remedial sealant looks like in West Barnes
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
In the older streets around Holy Cross, walls and floors in older homes can move, and sealant and grout show it first. West Barnes is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
