Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Westenhanger. Fully insured, ARBOMaster approved and guaranteed for a year.

How we handle external mastic in Westenhanger
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on façade panels, render & cladding joints and joints between brick and frames, and the jobs we see most are brick movement joints where the sealant has split and failed seals between different materials.
Outside joints can only be sealed when they’re dry, so work in Westenhanger is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Every job comes with a one-year guarantee, wherever you are in Kent.

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. For a village or hamlet like Westenhanger, 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 we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

Related advice
Different surfaces, different methods
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Older cottages and farmhouses around Westenhanger can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

What else we do in Westenhanger
Your questions about external mastic in Westenhanger
Is Westenhanger within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Westenhanger station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do you work at height?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Westenhanger buildings and the weather
Westenhanger is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Westenhanger Castle (about 0.3 miles north-west) nearby, there’s older building stock in the area around Westenhanger as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around All Saints Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Lympne Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What we are called out for in Westenhanger
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
The most common problems we see are:
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
Letting a property close to Westenhanger station? Then split movement joints are easy to miss on a rental until damp shows inside.
