What happens on the day
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Upper Froyle, 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.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit

Advice
External mastic for homes and businesses in Upper Froyle
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you’re dealing with moss and dirt in joints with no sealant left and joints pointed up with cement by mistake, we can help, whatever the surface.
External sealant needs dry, clean surfaces, so work around Upper Froyle is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Walls and rooflines in Upper Froyle
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

In the older streets around Church of St Mary of the Assumption, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.
Where we work in Upper Froyle
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Concrete & block
What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Why it’s worth doing now in Upper Froyle
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Upper Froyle, older homes often have timber in their floors and frames, and water through a failed joint can rot timber 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 the work is at height. We take all of that into account in your quote.

What we are called out for in Upper Froyle
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Keep an eye out for these signs:
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Failed seals between different materials
- Water getting into walls through failed joints
If you let a flat or house near Bentley (Hampshire) station, split movement joints are easy to miss on a rental until damp shows inside.
