What external mastic looks like in Southchurch
Southchurch is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
In the older streets around Church of the Holy Trinity, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Hamstel Infant School and Nursery, its movement joints, gutters and trims need looking after like any other building’s.

External mastic for homes and businesses in Southchurch
For buildings in Southchurch, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Common call-outs are for sealant that has lost its bond to the brick or render and failed seals between different materials, across copings & trims, render & cladding joints and brickwork movement joints.
Houses in smaller places like Southchurch can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. That’s where gutter joints and wall joints tend to fail first.
Whatever the size of the job, it’s backed by our one-year guarantee in Southchurch and across Southend-on-Sea.

When to call us in Southchurch
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
The most common problems we see are:
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
- Weeds or debris growing in open joints
Letting a property close to Southend East station? Then split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- Whether they’re fully insured
- How the joint is cleaned and prepared
Southchurch: your questions answered
I let a flat near Southend East station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Southchurch within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are 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.
What we can’t put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Where we work in Southchurch
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Façade panels
- Copings & trims
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
- Check external joints each spring
Keep the joints clear of soil, plants and climbing growth. 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.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. For a job in Southchurch, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Tell us if parking is tricky
