About our external mastic in Coxhill Green
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have brick movement joints where the sealant has split and panel joints letting water in, we can put it right.
External sealant needs dry, clean surfaces, so work around Coxhill Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, whatever its size.

Your questions about external mastic in Coxhill Green
Do you cover Coxhill Green for external mastic?
Yes. We work across London and the South East, and Coxhill Green is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Longcross station?

What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so it doesn’t stand out.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Are you fully insured?
Yes, we’re fully insured for every job we do.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.

Common problems we fix in Coxhill Green
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The most common problems we see are:
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
Rented homes near Longcross station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

What else we do in Coxhill Green
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Somewhere as small as Coxhill Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

External mastic in Coxhill Green: local notes
With historic houses such as Botleys Mansion (about 3.5 miles north-east) nearby, there’s older building stock in the area around Coxhill Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as St Lawrence CofE (Aided) Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St Lawrence, older walls, gutters and the joints where extensions meet them need a flexible sealant.
