What the job involves on each surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
External mastic in West Street
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with weeds or debris growing in open joints and joints with sealant missing in places, we can help, on façade panels, concrete & block and joints between brick and frames alike.
In a village or hamlet like West Street, 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 comes with a 12-month guarantee, wherever you are in Kent.

Your questions about external mastic in West Street
Do you work for landlords with property near Lenham station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to West Street?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What does external mastic cost?
We don’t publish prices, because the cost 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.
How long does external mastic last?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.

Landlords and agents in West Street can book us as well as householders. Resealing between tenancies keeps a property looking cared for.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Common problems we fix in West Street
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Signs it’s time to call us include:
- Failed sealant between panels on a façade
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
Schools such as The Lenham School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

West Street buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Leeds Castle (about 4.2 miles west) nearby, there’s older building stock in the area around West Street as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Lenham station? Then split movement joints are easy to miss on a rental until damp shows inside. Leeds Castle, about 4.2 miles west, is one of the historic houses in the wider area around West Street, and older homes nearby need a sealant that suits their walls.

For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.

Advice
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
- Avoid pressure-washing directly into sealant joints
- Leave the joints unpainted unless we have said otherwise
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
