External mastic for homes and businesses in Muddles Green
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we do not skip that step. We work on render & cladding joints, joints between brick and frames and brickwork movement joints, and the jobs we see most are moss and dirt in joints with no sealant left and rain getting behind render or cladding at a joint.
External sealant needs dry, clean surfaces, so work around Muddles Green is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, large or small.

What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Muddles Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Keeping the joints in good condition
So the new joints stay in good condition:
- Wash walls gently around the sealant
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Muddles Green, 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, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Clear the area around the work

External mastic in Muddles Green: local notes
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. With historic houses such as Horselunges Manor (about 2.2 miles south-east) nearby, there’s older building stock in the area around Muddles Green as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as The Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Berwick (Sussex) station, split movement joints are easy to miss on a rental until damp shows inside.

What we are called out for in Muddles Green
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
The most common problems we see are:
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Joints with sealant missing in places
- Joints pointed up with cement by mistake
If you look after a building such as Chiddingly Primary School, larger buildings have long runs of movement joint that eventually need resealing.
