When to call us in Mile Oak
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Any of these means the joints need attention:
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
Homes close to St Andrew's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include

About our external mastic in Mile Oak
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have sealant pulling away from one side of the joint and water getting into walls through failed joints, we can help, whatever the surface.
Somewhere as small as Mile Oak, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Aftercare tips
So the new joints stay in good condition:
- Avoid pressure-washing directly into sealant joints
- Leave the joints unpainted unless we’ve said otherwise
- Act on the first splits you see
- Walk round the building once a year and look at the joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
FAQs for Mile Oak
Can you help a landlord with a rental near Paddock Wood station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is Mile Oak in your area for external mastic?
Yes. We work across London and the South East, and Mile Oak is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is normally a movement joint. It gives the wall room to move.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
What we cannot put right
In fairness, there are a few things sealant will not fix:
- Damp that is not coming from the joint
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.
What we seal

What else we do in Mile Oak
Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Send us any details you have about the façade.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Around Mile Oak, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

The process
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Mile Oak, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we will 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.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
