External mastic in Eastling, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. If you are dealing with hard, crazed mastic that has stopped moving and weeds or debris growing in open joints, we can help, on copings & trims, brickwork movement joints and joints between brick and frames alike.
External sealant needs dry, clean surfaces, so work around Eastling is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?
If you’re 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 fails, we can still redo it.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What else we do in Eastling
Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly where it can be done safely.
Eastling: your questions answered
Do you cover Eastling for external mastic?
Yes. We work across London and the South East, and Eastling is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Will you come out to Eastling?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.
Are you insured?
Yes. We’re fully insured.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Brickwork movement joints
- Façade panels
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Eastling, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

Aftercare tips
To keep the joints looking good and working properly:
- Deal with leaking gutters that soak the joints below
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Outside joints around Eastling
With historic houses such as Belmont House and Gardens (about 1.4 miles east) nearby, there’s older building stock in the area around Eastling as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Teynham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Advice
Common problems we fix in Eastling
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
If you can see any of these, it’s time to have the joints looked at:
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
Schools such as Eastling Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
