External Mastic in Butcher's Cross
Our applicators work in Butcher's Cross on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- The size of the job
- How easy the joints are to reach
- When we can work, for business premises
- The type of sealant required
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- The type of property
- The address or postcode of the job
For a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.
About our external mastic in Butcher's Cross
On houses, flats and commercial buildings across Butcher's Cross, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Typical jobs include failed sealant between panels on a façade and moss and dirt in joints with no sealant left, across façade panels, brickwork movement joints and joints between brick and frames.
In a village or hamlet like Butcher's Cross, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, it’s backed by our one-year guarantee.

Different surfaces, different methods
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
Butcher's Cross questions
Can you help a landlord with a rental near Crowborough station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover Butcher's Cross for external mastic?
Yes, Butcher's Cross is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
What we can’t put right
Before booking, it’s worth knowing the limits too:
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on the building from start to finish. Somewhere like Butcher's Cross needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Tell us about any water getting in

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Common problems we fix in Butcher's Cross
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Any of these means the joints need attention:
- Old sealant gone brittle and cracked
- Joints pointed up with cement by mistake
- Failed seals between different materials
- Leaking joints around cladding and façade panels
Rented homes near Crowborough station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Outside joints around Butcher's Cross
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of the Good Shepherd, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Skippers Hill Manor School? Then larger buildings have long runs of movement joint that eventually need resealing.
