External mastic in Black Notley
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on joints between brick and frames, render & cladding joints and concrete & block, and people most often call us about failed seals between different materials and sealant that has lost its bond to the brick or render.
Older homes in small places like Black Notley may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
All our work is covered by a 12-month guarantee, wherever you are in Essex.

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Where a wall is exposed, as many are in small places like Black Notley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Black Notley questions
Do you cover Black Notley for external mastic?
Yes. We work across London and the South East, and Black Notley is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Will you come out to Black Notley?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
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 reseal at that point.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building. Your quote will say how long we expect yours to take.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Black Notley buildings and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Braintree Sixth Form? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St Peter and St Paul include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Cressing station, split movement joints are easy to miss on a rental until damp shows inside.

Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Don’t let climbing plants root in the sealant
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
- Leave the joints unpainted unless we have said otherwise
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.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
How it works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work usually takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Black Notley, 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
