External mastic in Rose Green
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. We are often asked to deal with weeds or debris growing in open joints and failed sealant between panels on a façade, on façade panels, joints between brick and frames and concrete & block.
External sealant needs dry, clean surfaces, so work around Rose Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job.

What external mastic looks like in Rose Green
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 landlords with property near Chappel & Wakes Colne station, outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Church of St Barnabas, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common problems we fix in Rose Green
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Look out for any of the following:
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint
- Joints with sealant missing in places
- Failed sealant between panels on a façade
Managing a site like Chappel Church of England Controlled Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Render that is blown, hollow or coming away
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Where we work in Rose Green
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
- Concrete & block

How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Point out the joints to other trades
- Clear growth from the base of walls and joints
- Keep movement joints as flexible joints, not mortar
- Deal with leaking gutters that soak the joints below
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. The work generally takes anything from a few hours to several days, depending on the building. Somewhere like Rose Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Rose Green questions
Do you cover smaller places like Rose Green?
Yes. Rose Green 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.
Do you cover Rose Green for external mastic?
Yes. Our work covers London and the South East, and Rose Green is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Rose Green.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
