About our external mastic in Cheriton
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on brickwork movement joints, copings & trims and façade panels, and people most often call us about panel joints letting water in and water getting into walls through failed joints.
Houses in smaller places like Cheriton can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.

How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.

What we’re called out for in Cheriton
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Keep an eye out for these signs:
- Panel joints letting water in
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Cracked joints where brick meets render or frames
If you let a flat or house near Folkestone West station, split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before booking
- How the joint is cleaned and prepared
- Who turns up on the day
- Whether they’re fully insured

Walls and rooflines in Cheriton
Cheriton is within about 1 mile 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 Acrise Place (about 3.4 miles north) nearby, there’s older building stock in the area around Cheriton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as All Soul's Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of All Souls, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. In a smaller place like Cheriton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

FAQs for Cheriton
Do you cover smaller places like Cheriton?
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.
Does living near the coast affect external mastic in Cheriton?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
How do you reach high-level joints?
Each building is different. Send us photos and a rough idea of the height, and we’ll confirm what access is needed.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
