How we handle external mastic in Vines Cross
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with joints with sealant missing in places and gaps where render, brick and frames meet, we can put it right.
Older homes in small places like Vines Cross may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
Whatever the size of the job, you get the same one-year guarantee.

What sealant work can’t fix
To be straight with you, there are a few things sealant won’t fix:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Render that’s blown, hollow or coming away
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
What we seal

- Concrete & block

How the job changes by surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.

What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. In a small place like Vines Cross, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Why it’s worth doing now in Vines Cross
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. In a small place like Vines Cross, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- Approved under the ARBOMaster scheme
- Colour picked to suit the job
- Any old sealant cut out fully, not covered over
- We leave the area clean and tidy

Common problems we fix in Vines Cross
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Joints pointed up with cement by mistake
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Sealant pulling away from one side of the joint
For site and facilities teams at buildings such as Maynards Green Community Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Vines Cross buildings and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Horselunges Manor (about 3.6 miles south) nearby, there’s older building stock in the area around Vines Cross as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around The Parish Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Asking for a quote
When you call or email, these details help:
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- The address or postcode of the job
- What’s wrong with the joints now
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep soil, plants and ivy away from the joints
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
- Never let anyone fill a movement joint with mortar
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Vines Cross: your questions answered
Can you do external mastic in Vines Cross?
Yes. Our work covers London and the South East, and Vines Cross is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is external mastic in Vines Cross guaranteed?
All our work, in Vines Cross and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
