About our external mastic in Beal's Green
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include weathered mastic that no longer stretches and joints with sealant missing in places, on copings & trims, façade panels and concrete & block.
In a village or hamlet like Beal's Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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.

Why it’s worth doing now in Beal's Green
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Beal's Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
What you get with us
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator
- We never seal over old sealant
- Neat joints and a tidy finish

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Make sure movement joints are not pointed over
- Have failed joints looked at early
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
External mastic in Beal's Green: local notes
With historic houses such as Scotney Castle (about 5 miles north-west) nearby, there’s older building stock in the area around Beal's Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Etchingham station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Signs you need external mastic in Beal's Green
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Signs it’s time to call us include:
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
- Panel joints letting water in
Schools such as Marlborough House School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Whether all the old sealant comes out first
- What the cure time is
- Which sealant they’ll use, and why
- Is VAT in the price?
Common questions in Beal's Green

Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.

The job normally takes anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. For a village or hamlet like Beal's Green, the journey is planned in advance: let us know about lanes, gates and parking.

- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Advice
What we cannot put right
A few problems are outside what sealant work can do:
