Pevensey External Mastic
Movement joints in Pevensey need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
Signs you need external mastic in Pevensey
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Common reasons people contact us are:
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
Managing a site like Pevensey and Westham CofE Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

About our external mastic in Pevensey
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on concrete & block, joints between brick and frames and copings & trims, and the jobs we see most are damp patches traced to an open external joint and failed sealant between panels on a façade.
Older homes in small places like Pevensey may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
All our work comes with a 12-month guarantee, wherever you are in East Sussex.

Questions from Pevensey
Can you help a landlord with a rental near Pevensey Bay station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Pevensey?
Yes. Pevensey is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What external mastic looks like in Pevensey
Pevensey 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. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St. Nicolas Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Pevensey Bay station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Leave it or put it right?
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Pevensey, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Honest limits
To be straight with you, there are a few things sealant will not fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Render that is blown, hollow or coming away
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
- Concrete & block
- Render & cladding joints
Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
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.

The process
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. In a small place like Pevensey, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
