About our external mastic in Begbroke
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We work on concrete & block, joints between brick and frames and brickwork movement joints, and the jobs we see most are cracked joints where brick meets render or frames and water getting into walls through failed joints.
Older homes in small places like Begbroke may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
All our work comes with our 12-month guarantee.

Common problems we fix in Begbroke
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
These are the problems we are asked about most:
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
- Sealant that has lost its bond to the brick or render
For landlords with property near Oxford Parkway station, split movement joints are easy to miss on a rental until damp shows inside.

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Check external joints each spring
- Ask before painting over external sealant
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Outside joints around Begbroke
With historic houses such as Blenheim Palace (about 2.2 miles north-west) nearby, there’s older building stock in the area around Begbroke as well as newer homes. Where a home is older, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as William Fletcher Primary School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Philip include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the building. In a small place like Begbroke, access is usually the main thing to plan. 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Advice
What else we do in Begbroke
Begbroke: your questions answered
Do you cover Begbroke for external mastic?
Yes, Begbroke is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Is Begbroke within the area you cover?
Yes. Begbroke is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Begbroke, along with the rest of our area.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before work begins from the range available.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
