External mastic in Parkeston, done properly
For buildings in Parkeston, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you are dealing with weathered mastic that no longer stretches and gaps where render, brick and frames meet, we can put it right, whatever the surface.
Somewhere as small as Parkeston, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Older cottages and farmhouses around Parkeston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Parkeston: your questions answered
Does the coastal weather in Parkeston affect outside sealant?
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.
Do you work for landlords with property near Harwich International station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
What should I tell you?
Let us know what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
Do you come to Parkeston?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Landlord and commercial work in Parkeston
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Surface by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Subsidence or other structural problems
- Damp that is not coming from the joint
- Render that’s blown, hollow or coming away
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
Joints and surfaces we work on
- Concrete & block
- Joints between brick and frames
- Façade panels
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
Do you need external mastic in Parkeston?
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
Letting a property close to Harwich International station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Parkeston buildings and the weather
Parkeston 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. 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.
Homes close to St Paul's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Spring Meadow Primary School & School House Nursery are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
