External & façade joints in Oliver's Battery, Hampshire
Our applicators work in Oliver's Battery on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
- Sealant pulling away from one side of the joint
How we handle external mastic in Oliver's Battery
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. We work on façade panels, copings & trims and joints between brick and frames, and common reasons people get in touch are cracked joints where brick meets render or frames and weathered mastic that no longer stretches.
Outside joints can only be sealed when they’re dry, so work in Oliver's Battery is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Where a wall is exposed, as many are in small places like Oliver's Battery, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. In a small place like Oliver's Battery, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.

External mastic in Oliver's Battery: local notes
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.
If you let a flat or house near Shawford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Saint Mark's, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Keeping the joints in good condition
Looking after new joints is easy:
- Show decorators and builders where the movement joints are
- Don’t let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Act on the first splits you see
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
FAQs for Oliver's Battery
Can you help a landlord with a rental near Shawford station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Is Oliver's Battery within the area you cover?
Yes, Oliver's Battery is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
What information do you need?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
How long will you be here?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we will tell you how long to expect.
Signs you need external mastic in Oliver's Battery
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Most people get in touch when they notice something like this:
- Failed sealant between panels on a façade
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
If you look after a building such as Olivers Battery Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Different surfaces, different methods
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.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
