External & façade joints in Buckland, Buckinghamshire
Movement joints in Buckland need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
External mastic in Buckland, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on render & cladding joints, copings & trims and joints between brick and frames, and the jobs we see most are leaking joints around cladding and façade panels and joints with sealant missing in places.
Older homes in small places like Buckland may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
A 12-month guarantee comes as standard, so you are covered after we have gone.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Act on the first splits you see
- Keep movement joints as flexible joints, not mortar
- Avoid pressure-washing directly into sealant joints
- Look over the joints every year, ideally after winter
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Outside joints around Buckland
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Cholesbury Manor House (about 4.2 miles south-east) nearby, there’s older building stock in the area around Buckland as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Wendover station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Aston Clinton School, its movement joints, gutters and trims need looking after like any other building’s.

Will you come out to Buckland?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Buckland in your area for external mastic?
Yes, Buckland is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.

Signs you need external mastic in Buckland
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Most people get in touch after spotting something like this:
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
For an older house near a landmark such as Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why deal with it now?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Around Buckland, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

The process
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Buckland needs a little journey planning: 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.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
