External mastic in Nackington, done properly
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. We work on copings & trims, brickwork movement joints and render & cladding joints, and common reasons people get in touch are joints where the bead has come unstuck and rigid filler in a joint that should flex.
Around Nackington, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
All our work is covered by our 12-month guarantee.

FAQs for Nackington
Will you come out to Nackington?
Yes, Nackington is covered. 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.
Do you work for landlords with property near Canterbury East station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
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.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Nackington, along with the rest of our area.
Do you need external mastic in Nackington?
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Moss and dirt in joints with no sealant left
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
- Old sealant gone brittle and cracked
Managing a site like Simon Langton Grammar School for Boys? Then larger buildings have long runs of movement joint that eventually need resealing.

Work for landlords, hotels and businesses

Aftercare tips
So the new joints stay in good condition:
- Act on the first splits you see
- Check external joints each spring
- Point out the joints to other trades
- Never let anyone fill a movement joint with mortar
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. Somewhere as small as Nackington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any tricky access
- Clear the area around the work
- Keep pets and children clear of the area while we work

Advice
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Nackington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
External mastic in Nackington: local notes
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.
If you let a flat or house near Canterbury East 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 Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.
