About our external mastic in Cooper's Green
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 does not stand out. Typical jobs include failed sealant between panels on a façade and hard, crazed mastic that has stopped moving, on brickwork movement joints, joints between brick and frames and façade panels.
Around Cooper's Green, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Whatever the size of the job, you get the same 12-month guarantee in Cooper's Green and across East Sussex.

We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

What external mastic looks like in Cooper's Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Five Ash Down Independent Chapel, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Buxted station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Signs you need external mastic in Cooper's Green
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Most people get in touch when they notice one of these:
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
Schools such as Bonners CofE School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- How long the guarantee is
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- Which colour the sealant will be
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Cooper's Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area

Advice
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Cooper's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

When something else is needed
A few problems are outside what sealant work can do:
- Structural movement, which needs a surveyor or engineer
- Render that is blown, hollow or coming away
- Walls that need new movement joints cut into them
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Joints between brick and frames
- Copings & trims
- Concrete & block
- Façade panels
- Brickwork movement joints
- Render & cladding joints
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Never let anyone fill a movement joint with mortar
- Check external joints each spring
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
