About our external mastic in Shanklin Village
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. If you’re dealing with old sealant gone brittle and cracked and sealant pulling away from one side of the joint, we can help, whatever the surface.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Shanklin Village, it’s worth checking who is responsible for the outside before booking.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Aftercare tips
So the new joints stay in good condition:
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Tell anyone working on the walls about the movement joints
- Keep high-pressure jets off the joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Shanklin Village buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
Letting a property close to Belmont station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Harris Academy Sutton, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St John, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Shanklin Village questions
Is Shanklin Village in your area for external mastic?
Yes. Our work covers London and the South East, and Shanklin Village is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Belmont station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. The work normally takes a few hours to a few days, depending on the length of joint and the access. For a job in Shanklin Village, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Honest limits
It helps to know what we cannot do too:
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
- Movement that is more than a sealant joint can take
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
