Bepton External Mastic
Our applicators work in Bepton on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Panel joints letting water in
- Weathered mastic that no longer stretches
- Rigid filler in a joint that should flex
External mastic in Bepton, done properly
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We’re often asked to deal with water getting into walls through failed joints and movement joints with cracked, split or missing sealant, on concrete & block, copings & trims and façade panels.
Around Bepton, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

What the job involves on each surface
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
When it is not the sealant
It helps to know what we can’t do:
- Movement that is more than a sealant joint can take
- Render that’s blown, hollow or coming away
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
- Façade panels
Do you need external mastic in Bepton?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Moss and dirt in joints with no sealant left
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
If you live in an older home near The Parish Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before you book

- What preparation is included

Bepton buildings and the weather
With historic houses such as Cowdray House (about 2.7 miles north-east) nearby, there’s older building stock in the area around Bepton as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.
In and around Bepton, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Work for landlords, hotels and businesses
For anyone letting property in or around Bepton, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building. Somewhere as small as Bepton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Bepton: your questions answered
Can you do external mastic in Bepton?
Yes. We work across London and the South East, and Bepton is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Will you come out to Bepton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you work at height?
It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we will confirm what access is needed.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a small place like Bepton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.
