External mastic in Tankerton
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. Common call-outs are for gaps where render, brick and frames meet and failed sealant between panels on a façade, on façade panels, joints between brick and frames and render & cladding joints.
Houses in smaller places like Tankerton can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
Each job carries a 12-month guarantee, whatever its size.

Why act early in Tankerton
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Homes in smaller places like Tankerton can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why us?
- We never seal over old sealant
- Homes, businesses and hotels
- Neat joints and a tidy finish
- White, clear, grey or coloured to suit, where the product allows

External mastic in Tankerton: local notes
Tankerton is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of 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 Church of All Saints include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Whitstable station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Keep movement joints as flexible joints, not mortar
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Parking around Tankerton is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
DIY sealant or a professional job?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What else we do in Tankerton
Signs you need external mastic in Tankerton
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
If you look after a building such as St Mary's Catholic Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- What preparation is included
- What product goes in the joint
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
Common questions in Tankerton
Will you come out to Tankerton?
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.
I let a flat near Whitstable station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can you reach joints on upper floors?
Each building is different. Send us pictures and a rough idea of the height.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
How long will you be here?
A typical job takes anything from a few hours to several days, depending on the building. We’ll confirm how long when we quote.
