External Mastic in Westridge
Professional external mastic in and around Westridge, with every bit of old sealant taken out first and a 12-month guarantee.
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
External mastic in Westridge, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on brickwork movement joints, copings & trims and joints between brick and frames, and common reasons people get in touch are joints with sealant missing in places and gaps where render, brick and frames meet.
Somewhere as small as Westridge, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
A one-year guarantee comes as standard.

Your questions about external mastic in Westridge
Will you come out to Westridge?
Yes, Westridge is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Smallbrook Junction station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How long does external mastic take?
It depends on the size of the job, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
When is the sealant fully cured?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
When it is not the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Westridge 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.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
Ask for a quote
Asking for a quote is easy: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.

Common problems we fix in Westridge
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
Any of these means the joints need attention:
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
Letting a property close to Smallbrook Junction station? Then split movement joints are easy to miss on a rental until damp shows inside.

External mastic in Westridge: local notes
Westridge is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around St John's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Schools such as Oakfield Church of England Aided Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Act on the first splits you see
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
- Make sure movement joints aren’t pointed over
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
