External & façade joints in Milebush, Kent
External mastic across Milebush and nearby, with old sealant always removed completely.
- Gaps where render, brick and frames meet
- Movement joints filled with mortar instead of sealant
- Weathered mastic that no longer stretches
External mastic for homes and businesses in Milebush
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on façade panels, joints between brick and frames and copings & trims, and people most often call us about rain getting behind render or cladding at a joint and plants rooting in failed movement joints.
In a village or hamlet like Milebush, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Your job is guaranteed for a year, as with all our work.

What the job involves on each surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Rising or penetrating damp from elsewhere in the wall
- Render that is blown, hollow or coming away
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Common problems we fix in Milebush
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
People usually contact us when they notice one of these:
- Rigid filler in a joint that should flex
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
If you let a flat or house near Marden station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before we start. The work usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Milebush, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Tell us about any water getting in
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

External mastic in Milebush: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St Michael and All Angels Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
