Stadhampton External Mastic
Problem with your movement joints in Stadhampton? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
Common problems we fix in Stadhampton
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
Any of these means the joints need attention:
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
Homes close to Church of St John the Baptist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic in Stadhampton
For buildings in Stadhampton, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on façade panels, joints between brick and frames and copings & trims, and common reasons people get in touch are plants rooting in failed movement joints and brick movement joints where the sealant has split.
External sealant needs dry, clean surfaces, so work around Stadhampton is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, whatever its size.

External mastic in Stadhampton: local notes
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 Garsington Manor (about 2.5 miles north-west) nearby, there’s older building stock in the area around Stadhampton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Radley station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Stadhampton Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
Stadhampton is about 6 miles south-east of Oxford, in Oxfordshire. Jobs in Stadhampton get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Stadhampton is one of 443 towns and villages in Oxfordshire where we work. We also work in Oxford, around 6 miles away.

What’s near Stadhampton
Locally, jobs take us to homes and businesses close to The Crown pub, among other places. Stadhampton’s nearest station is Radley station, roughly 4.8 miles west. Well-known places in the area include Aston Martin Heritage Trust Museum (1.6 miles south) and Littlemore Hospital (4.8 miles north-west). For a walk, there’s Wells Farm and Wittenham Clumps.
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Stadhampton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Questions from Stadhampton
Do you cover smaller places like Stadhampton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Radley station. Can you help?

Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Different surfaces, different methods
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Stadhampton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height

Advice
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Façade panels
- Render & cladding joints
- Brickwork movement joints
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
- Ask before painting over external sealant
- Have failed joints looked at early
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
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.
