External Mastic in White Roding
Movement joints in White Roding need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
When it isn’t the sealant
Sealant is not the answer to every problem, and we will tell you before we start. It won’t solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Rising or penetrating damp from elsewhere in the wall
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.

- Concrete & block
- Façade panels

External mastic for homes and businesses in White Roding
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you’re dealing with sealant pulling away from one side of the joint and rain getting behind render or cladding at a joint, we can help, on render & cladding joints, joints between brick and frames and concrete & block alike.
Older homes in small places like White Roding may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Our work is backed for twelve months.

Outside joints around White Roding
With historic houses such as Barrington Hall (about 2.9 miles north) nearby, there’s older building stock in the area around White Roding as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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 St Martin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

The process
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like White Roding needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- 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
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

FAQs for White Roding
Can you do external mastic in White Roding?

Do you work for landlords and businesses?

Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Are you insured?
Yes, we are fully insured for every job we do.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.

Yes, we can. Several rooms, windows or areas can go on one quote.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
What we are called out for in White Roding
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Most people get in touch after spotting one of these:
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
Letting a property close to Sawbridgeworth station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
- Check the sealant is paintable before painting near it
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Why it’s worth doing now in White Roding
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Older cottages and farmhouses around White Roding can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
