Breach Barns External Mastic
We cover Breach Barns for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Joints where the bead has come unstuck
- Gaps where render, brick and frames meet
- Rain getting behind render or cladding at a joint
What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. In a small place like Breach Barns, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

External mastic in Breach Barns, done properly
For buildings in Breach Barns, 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. If you’re dealing with sealant pulling away from one side of the joint and weathered mastic that no longer stretches, we can put it right, whatever the surface.
Older homes in small places like Breach Barns may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
All our work comes with our one-year guarantee.

Walls and rooflines in Breach Barns
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Upshire Primary Foundation School? Then its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Cheshunt station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What affects the quote in Breach Barns
The quote reflects the job in front of us. We look at:
- When we can work, for business premises
- Access and height
- The size of the job
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- A few photos by email, if you can
- How we’d reach the joints
- If someone has resealed it before
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Surface by surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Why act early in Breach Barns
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. In a small place like Breach Barns, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
How long does external mastic take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation. We will confirm how long when we quote.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Signs you need external mastic in Breach Barns
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Most people get in touch when they notice something like this:
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
Homes close to Church of St Thomas include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- When the joint can take water or movement
- The length of the guarantee
- What preparation is included
- Whether the sealant suits the joint
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 need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
