External mastic for homes and businesses in Shippon
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you have movement joints filled with mortar instead of sealant and hard, crazed mastic that has stopped moving, we can help, on copings & trims, concrete & block and façade panels alike.
Somewhere as small as Shippon, 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.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What else we do in Shippon
External mastic in Shippon: local notes
Historic houses like Appleton Manor (about 3.1 miles north-west) are a reminder that the area around Shippon has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Homes close to Church of St Mary Magdalene include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Radley station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Larkmead School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

For a walk, there’s Cumnor Hill and Dry Sandford Pit.
Leave it or put it right?
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Shippon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Landlord and commercial work in Shippon
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that is blown, hollow or coming away
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Common questions in Shippon
Do you cover smaller places like Shippon?
Yes. Shippon is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Radley station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Are you fully insured?
Yes. Full insurance covers our work.
Where do you work from?
We work from Crawley. We cover Shippon and the rest of Oxfordshire, along with the rest of our area.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Looking after it afterwards
After the cure time, these simple habits help:
- Look over the joints every year, ideally after winter
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement 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.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere as small as Shippon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Move anything stored near the joints
