External mastic for homes and businesses in Bramshaw
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. If you have cracked joints where brick meets render or frames and movement joints filled with mortar instead of sealant, we can put it right, on façade panels, concrete & block and brickwork movement joints alike.
Around Bramshaw, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in Bramshaw
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Common reasons people contact us include:
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
In the older streets around Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.

The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Somewhere as small as Bramshaw, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
How long does external mastic take?
Most jobs take anything from a few hours to several days, depending on the building. We will confirm how long when we quote.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
What external mastic looks like in Bramshaw
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Landford Manor (about 2.3 miles north) are a reminder that the area around Bramshaw has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Landlord and commercial work in Bramshaw
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Landlords and letting agents in Bramshaw can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Looking after it afterwards
Aftercare is simple:
- Act on the first splits you see
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
