External mastic in Nazeing, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. If you’re dealing with sealant that has lost its bond to the brick or render and joints pointed up with cement by mistake, we can put it right.
External sealant needs dry, clean surfaces, so work around Nazeing is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Every job comes with a 12-month guarantee, wherever you are in Essex.

What external mastic looks like in Nazeing
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Roydon station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Your questions about external mastic in Nazeing
I let a flat near Roydon station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Nazeing?
Yes, Nazeing is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Do you work at height?
Each building is different. Send us pictures and a rough idea of the height and we will confirm how they can be reached safely.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How it works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Nazeing, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about any water getting in
- Move anything stored near the joints

Advice
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Act on the first splits you see
- Point out the joints to other trades
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Common problems we fix in Nazeing
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for any of the following:
- Panel joints letting water in
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
For an older house near a landmark such as Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, 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.
