Outside joints around Chale
Chale is close to 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. 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.
Around Chale, as everywhere, external mastic is only as good as the preparation behind it.

External mastic in Chale, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. 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 concrete & block, brickwork movement joints and copings & trims, and common reasons people get in touch are water getting into walls through failed joints and plants rooting in failed movement joints.
Older homes in small places like Chale may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Our work is backed for twelve months, in Chale and everywhere else we cover.

Common questions in Chale
Is Chale in your area for external mastic?
Yes, Chale is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Does living near the coast affect external mastic in Chale?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What is backing rod for?
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 you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
How much does external mastic cost in Chale?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the quote in Chale
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any working-time requirements on site
- The product the joint needs
- How easy the joints are to reach
- The amount of work
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before we start.
Asking for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- How we’d reach the joints
- Whether it’s a home or a business
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What happens on the day
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Chale needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

Advice
What we cannot put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Joints between brick and frames

- Concrete & block
- Façade panels
- Brickwork movement joints
How the job changes by surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Why it’s worth doing now in Chale
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. Around Chale, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.

What else we do in Chale
Common problems we fix in Chale
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
Keep an eye out for any of the following:
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
Homes close to St Andrew's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What to look for in a quote
- When the joint can take water or movement
- Which colour the sealant will be
- What product goes in the joint
- The length of the guarantee
