- Damp patches traced to an open external joint
About our external mastic in Oversland
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on render & cladding joints, joints between brick and frames and façade panels, and the jobs we see most are weeds or debris growing in open joints and sealant pulling away from one side of the joint.
In a village or hamlet like Oversland, older cottages and farm buildings often stand in the open, 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.
Our work is backed for twelve months, in Oversland and everywhere else we cover.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the sealant is paintable before painting near it
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
- Deal with leaking gutters that soak the joints below
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Honest limits
To be straight with you, there are a few things sealant will not fix:
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
- Render that’s blown, hollow or coming away
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Concrete & block
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Oversland can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Common questions in Oversland
Can you do external mastic in Oversland?
Yes, Oversland is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
I let a flat near Selling station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you need external mastic in Oversland?
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Common reasons people contact us are:
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
- Failed sealant between panels on a façade
- Cracked joints where brick meets render or frames
Managing a site like Boughton-under-Blean and Dunkirk Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Walls and rooflines in Oversland
With historic houses such as Belmont House and Gardens (about 4.8 miles west) nearby, there’s older building stock in the area around Oversland as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
In the older streets around Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Selling station, outside joints that have cracked can let damp into a rental, so check them between lets.

The process
On the day, 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 anything from a few hours to several days, depending on the building. Somewhere as small as Oversland, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
