About our external mastic in Pevensey Bay
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you’re dealing with gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving, we can put it right, on render & cladding joints, concrete & block and joints between brick and frames alike.
In a smaller place like Pevensey Bay, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
Your job is guaranteed for a year, as with all our work.

Looking after it afterwards
Looking after new joints is easy:
- Keep high-pressure jets off the joints
- Look over the joints every year, ideally after winter
- Leave the joints unpainted unless we’ve said otherwise
- Never let anyone fill a movement joint with mortar
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.
What external mastic looks like in Pevensey Bay
Pevensey Bay 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.
If you live in an older home near St Wilfrid's Church Pevensey Bay, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Pevensey Bay station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Signs you need external mastic in Pevensey Bay
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
For site and facilities teams at buildings such as Pevensey and Westham CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on the building from start to finish. Parking around Pevensey Bay is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on

Why act early in Pevensey Bay
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Around Pevensey Bay, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

DIY versus a professional finish
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, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Common questions in Pevensey Bay
Can you help a landlord with a rental near Pevensey Bay station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Pevensey Bay within the area you cover?
Yes, Pevensey Bay is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
