External mastic for homes and businesses in Froxfield 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. We work on joints between brick and frames, brickwork movement joints and façade panels, and the jobs we see most are joints with sealant missing in places and joints pointed up with cement by mistake.
Around Froxfield Green, 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.
You get a 12-month guarantee, the same in Froxfield Green as everywhere else we work.

Common problems we fix in Froxfield Green
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
If you can see any of these, it’s time to have the joints looked at:
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
For an older house near a landmark such as Church of St Peter on the Green, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. For a village or hamlet like Froxfield Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

Froxfield Green buildings and the weather
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.
Schools such as Froxfield Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the job changes by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Why act early in Froxfield Green
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Froxfield Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
