Surface by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
About our external mastic in Little Coxwell
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you’re dealing with rain getting behind render or cladding at a joint and moss and dirt in joints with no sealant left, we can put it right.
Older homes in small places like Little Coxwell may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Walls and rooflines in Little Coxwell
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Buscot Park (about 3.2 miles north-west) nearby, there’s older building stock in the area around Little Coxwell as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Faringdon Community College? Then its movement joints, gutters and trims need looking after like any other building’s.

What we’re called out for in Little Coxwell
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

It helps to know what we cannot do too:
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer

What else we do in Little Coxwell
Your questions about external mastic in Little Coxwell
What guarantee comes with external mastic in Little Coxwell?
All our work, in Little Coxwell and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover Little Coxwell for external mastic?
Yes. Our work covers London and the South East, and Little Coxwell is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Where are you based?
We work from Crawley. Our applicators cover Little Coxwell.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Leave it or put it right?
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Little Coxwell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why Little Coxwell customers choose us
- Any old sealant cut out fully, not covered over
- White, clear, grey or another colour, product permitting
- Anti-fungal sanitary silicone in wet areas
- Approved under the ARBOMaster scheme

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Little Coxwell 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.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
