Remedial sealant for homes and businesses in Barkingside
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. We work on mouldy bath & shower sealant, expansion joints and botched or over-sealed joints, and common reasons people get in touch are sealant that came away because the surface wasn’t prepared and mould trapped under a layer of silicone.
Hard London water leaves limescale on sealant, grout and taps alike. In Barkingside, remedial sealant is as much about a room looking cared for as about keeping water out.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What the job involves on each surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, then reseal neatly.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
How to look after the new joints
To keep the joints looking good and working properly:
- Deal with small splits early
- Don’t point over movement joints
- Clean sealant with mild products only
- Never seal over old silicone
Keep the room ventilated: use the extractor or open a window after showering.
Do not keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
Common problems we fix in Barkingside
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.
Most people get in touch after spotting something like this:
- Smears and lumps from a botched reseal
- Decorators’ caulk around a bath or shower
- Over-sealed joints coming away
- Floor or wall movement joints that have failed
For an older house near a landmark such as Children's Church And Lych Gate At Barnardo's, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Before you book anyone
- How the surfaces are prepared before sealing
- Who turns up on the day
- Which colour the sealant will be
- Is the old sealant removed completely?
The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a London area like Barkingside, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

Your questions about remedial sealant in Barkingside
Is parking an issue for remedial sealant in Barkingside?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Seven Kings station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Can you strip sealant from an acrylic tray safely?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. We point out any damage that’s already there.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you reseal a split movement joint?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you take off two layers of silicone?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Water damage behind tiles that needs a tiler
- Sealant in an older building that needs testing for asbestos first
- A leaking trap, valve or supply pipe
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
What we seal

What remedial sealant looks like in Barkingside
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.
As a London address, Barkingside can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Seven Kings station, botched sealant from a previous quick fix is easier to strip out between tenants.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

What else we do in Barkingside
What happens if it’s left?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
