External mastic for homes and businesses in Marlpit Hill
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on joints between brick and frames, copings & trims and brickwork movement joints, and common reasons people get in touch are joints with sealant missing in places and failed sealant between panels on a façade.
Older homes in small places like Marlpit Hill may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
A one-year guarantee comes as standard.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Marlpit Hill questions
Can you help a landlord with a rental near Edenbridge station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you do external mastic in Marlpit Hill?
Yes, Marlpit Hill is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you reach joints on upper floors?
Each building is different. Send us pictures and a rough idea of the height, and we’ll confirm what access is needed.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Why it’s worth doing now in Marlpit Hill
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a small place like Marlpit Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

External mastic in Marlpit Hill: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Chartwell (about 2.5 miles north) nearby, there’s older building stock in the area around Marlpit Hill as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as Edenbridge Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of St Peter and St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Do you need external mastic in Marlpit Hill?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for any of the following:
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
Rented homes near Edenbridge station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
