About our external mastic in Southminster
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We are often asked to deal with plants rooting in failed movement joints and water getting into walls through failed joints, across joints between brick and frames, copings & trims and façade panels.
In a smaller place like Southminster, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
All of our work is guaranteed for twelve months.

Aftercare tips
So the new joints stay in good condition:
- Have failed joints looked at early
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we’ve said otherwise
- Fix overflowing gutters above sealed joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
What affects the quote in Southminster
There’s no set price list, because no two jobs are the same. The quote depends on:
- Any mould that needs treating
- Working hours on commercial sites
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Where the property is
Need a quote? Please ring 0345 464 0079 or send us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Joints between brick and frames
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Façade panels
- Copings & trims

What external mastic looks like in Southminster
Rainfall in the South East is lower than in much 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 Leonard include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Southminster Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

When to call us in Southminster
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
The problems people generally mention when they call are:
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
For landlords with property near Southminster station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- What insurance they hold
- Whether the sealant suits the joint
- What the cure time is
- How much experience the applicator has
How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Southminster, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
