External mastic in Capel Cross, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on joints between brick and frames, concrete & block and render & cladding joints, and the jobs we see most are joints with sealant missing in places and weathered mastic that no longer stretches.
Around Capel Cross, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured.
How the visit 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 we start. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Capel Cross, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Mention if the joints have been sealed before

External mastic in Capel Cross: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Scotney Castle (about 3.4 miles south-west) are a reminder that the area around Capel Cross has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Marden station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Horsmonden Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one.
What happens if it’s left?
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Capel Cross can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
Why choose Mr Mastic in Capel Cross

What we cannot put right
We will not take on work that will not last, so here’s what sealant can’t put right:
- Failed render or damaged cladding panels
- Movement that is more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Copings & trims
- Façade panels
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
Do you need external mastic in Capel Cross?
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Most people get in touch when they notice one of these:
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
Historic houses such as Scotney Castle, about 3.4 miles south-west, show how far back building around Capel Cross goes, and older homes nearby need a sealant that suits their walls.

Questions from Capel Cross
Do you work for landlords with property near Marden station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is Capel Cross in your area for external mastic?
Yes. We work across London and the South East, and Capel Cross is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What is backing rod for?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so it doesn’t stand out.
