DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
About our external mastic in Bunce Common
On houses, flats and commercial buildings across Bunce Common, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you’re dealing with moss and dirt in joints with no sealant left and cracked joints where brick meets render or frames, we can put it right, on joints between brick and frames, façade panels and concrete & block alike.
Older homes in small places like Bunce Common may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Our work is backed for twelve months, in Bunce Common and everywhere else we cover.

Common problems we fix in Bunce Common
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, and it tears off the sides.
It’s worth asking for a quote if you see:
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
Letting a property close to Betchworth station? Then split movement joints are easy to miss on a rental until damp shows inside.

External mastic in Bunce Common: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Bartholomew, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why act early in Bunce Common
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Older cottages and farmhouses around Bunce Common can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
- Damp that is not coming from the joint
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
Where we work in Bunce Common
- Concrete & block
- Façade panels
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
Keeping the joints in good condition
After the cure time, these simple habits help:
- Leave the joints unpainted unless we’ve said otherwise
- Avoid pressure-washing directly into sealant joints
- Clear growth from the base of walls and joints
- Never let anyone fill a movement joint with mortar
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Bunce Common needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
