Saltwood External Mastic
Our applicators work in Saltwood on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Saltwood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky

Advice
External mastic for homes and businesses in Saltwood
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you have joints pointed up with cement by mistake and leaking joints around cladding and façade panels, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Saltwood is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Each job carries a 12-month guarantee, whatever its size.

Can I add another job to the visit?

External mastic in Saltwood: local notes
Saltwood is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
Rented homes near Sandling station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Saltwood CofE Primary School, its movement joints, gutters and trims need looking after like any other building’s.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep water from gutters off the wall
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Make sure movement joints are not pointed over
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and helps it last.
Signs you need external mastic in Saltwood
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for any of the following:
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
- Failed seals between different materials
For an older house near a landmark such as Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain.
