External mastic in Littlestone-on-Sea
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We are often asked to deal with leaking joints around cladding and façade panels and sealant that has lost its bond to the brick or render, across façade panels, joints between brick and frames and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Littlestone-on-Sea is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Littlestone-on-Sea: your questions answered
Can you do external mastic in Littlestone-on-Sea?
Yes. Our work covers London and the South East, and Littlestone-on-Sea is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Littlestone-on-Sea?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. We will reseal it with a flexible sealant.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the building. Larger jobs naturally take longer.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
What affects the quote in Littlestone-on-Sea
For a quick quote, just ask. What matters most is:
- The size of the job
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- Access and height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- Where the job is, and your postcode
- The problem you’ve noticed
- A few pictures by email, if you can
If you are in Littlestone-on-Sea and need external mastic, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How the job changes by 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 if the joint can be cleared.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. Somewhere like Littlestone-on-Sea needs a little journey planning: 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.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

When to call us in Littlestone-on-Sea
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
Homes close to Church of St Nicholas include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

What external mastic looks like in Littlestone-on-Sea
Littlestone-on-Sea is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as The Marsh Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Why it’s worth doing now in Littlestone-on-Sea
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Older cottages and farmhouses around Littlestone-on-Sea can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
