External mastic in Pell Green, done properly
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We work on copings & trims, façade panels and joints between brick and frames, and the jobs we see most are brick movement joints where the sealant has split and gaps where render, brick and frames meet.
Somewhere as small as Pell Green, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Pell Green: your questions answered
I let a flat near Wadhurst station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you cover Pell Green for external mastic?
Yes. Our work covers London and the South East, and Pell Green is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
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 have them redone then.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
How long does the job take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation. Your quote will say how long we expect yours to take.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
When something else is needed
In fairness, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint
- Failed render or damaged cladding panels
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
Surfaces we seal
- Render & cladding joints
- Façade panels
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
When to call us in Pell Green
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.
Most people get in touch when they notice one of these:
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
For landlords with property near Wadhurst station, outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
So the new joints stay in good condition:
- Don’t let climbing plants root in the sealant
- Ask before painting over external sealant
- Avoid pressure-washing directly into sealant joints
- Have failed joints looked at early
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
Walls and rooflines in Pell Green
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. With historic houses such as Wadhurst Castle (about 0.9 miles south-west) nearby, there’s older building stock in the area around Pell Green 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.
In the older streets around Rehoboth Chapel, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Wadhurst CofE Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Pell 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 walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before sealing.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
