External & façade joints in Botley, Oxfordshire
We cover Botley for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
- Weathered mastic that no longer stretches
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Loose or hollow render, which needs re-rendering
- Damp that isn’t coming from the joint
- Walls that need new movement joints cut into them
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Where we work in Botley
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Façade panels

- Render & cladding joints
External mastic in Botley
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the joint doesn’t stand out. We work on concrete & block, render & cladding joints and joints between brick and frames, and the jobs we see most are sealant that has lost its bond to the brick or render and damp patches traced to an open external joint.
In and around Botley, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Botley buildings and the weather
With historic houses such as Holywell Manor (about 2.3 miles east) nearby, there’s older building stock in the area around Botley as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Rented homes near Oxford station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Botley School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Signs you need external mastic in Botley
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
It’s worth asking for a quote if you see:
- Failed seals between different materials
- Rigid filler in a joint that should flex
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
Homes close to St Peter and St Paul include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for a handful of joints, longer for a whole elevation. Parking around Botley is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Why act early in Botley
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Around Botley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Botley questions
I let a flat near Oxford station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Botley?
Yes, Botley 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 you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
