About our external mastic in West Langdon
For buildings in West Langdon, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We’re often asked to deal with joints where the bead has come unstuck and failed sealant between panels on a façade, across copings & trims, joints between brick and frames and concrete & block.
Outside joints can only be sealed when they’re dry, so work in West Langdon is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All our work is covered by a 12-month guarantee, wherever you are in Kent.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like West Langdon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

External mastic in West Langdon: local notes
With historic houses such as Walmer Castle (about 3.9 miles north-east) nearby, there’s older building stock in the area around West Langdon as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Letting a property close to Martin Mill station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Langdon Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in West Langdon
Can you help a landlord with a rental near Martin Mill station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is West Langdon in your area for external mastic?
Yes, West Langdon is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
What is backing rod for?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Do you have insurance?
Yes. We are fully insured.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Fix overflowing gutters above sealed joints
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
What we can’t put right
A few problems are outside what sealant work can do:
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Concrete & block
- Copings & trims
Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Do you need external mastic in West Langdon?
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
Homes close to St Mary the Virgin include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
