External Mastic in Brabourne Lees
Sealing brickwork movement joints, render, cladding and façade joints in Brabourne Lees, with a 12-month guarantee on every job. Call for a quick quote.
- Joints with sealant missing in places
- Joints pointed up with cement by mistake
- Damp patches traced to an open external joint
Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant isn’t too deep.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
External mastic in Brabourne Lees, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We are often asked to deal with water getting into walls through failed joints and joints pointed up with cement by mistake, on façade panels, concrete & block and brickwork movement joints.
In a village or hamlet like Brabourne Lees, 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.
All our work is covered by a one-year guarantee, wherever you are in Kent.

Brabourne Lees buildings and the weather
With historic houses such as Westenhanger Castle (about 3.2 miles south-east) nearby, there’s older building stock in the area around Brabourne Lees as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Smeeth Community Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

When to call us in Brabourne Lees
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.
These are the problems we are asked about most:
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
For landlords with property near Westenhanger station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Brabourne Lees, 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.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Walk round the building once a year and look at the joints
- Keep movement joints as flexible joints, not mortar
- Wash walls gently around the sealant
- Leave the joints unpainted unless we’ve said otherwise
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.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Render that is blown, hollow or coming away
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Brabourne Lees questions
Is Brabourne Lees within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Westenhanger station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
How much does external mastic cost in Brabourne Lees?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
