External mastic in Causeway End, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. We work on façade panels, copings & trims and render & cladding joints, and common reasons people get in touch are plants rooting in failed movement joints and movement joints filled with mortar instead of sealant.
Outside joints can only be sealed when they’re dry, so work in Causeway End is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Outside joints around Causeway End
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of the Holy Cross, an extension built onto an older house moves differently, and the joint between them takes the strain.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why it’s worth doing now in Causeway End
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Causeway End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep high-pressure jets off the joints
- Fix overflowing gutters above sealed joints
- Act on the first splits you see
- Clear growth from the base of walls and joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
What we are called out for in Causeway End
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
The problems people usually mention when they call include:
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
Schools such as Felsted Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- When the joint can take water or movement
- How long the guarantee is
- Which colour the sealant will be
- How much experience the applicator has
FAQs for Causeway End
Do you cover Causeway End for external mastic?
Yes. We work across London and the South East, and Causeway End is part of that. Just call 0345 464 0079 or email us with a few details of the job.
What guarantee comes with external mastic in Causeway End?
All our work, in Causeway End and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Will the new joint stand out?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
