Littleworth Corner External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Littleworth Corner and across Slough. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
- Rain getting behind render or cladding at a joint
Common problems we fix in Littleworth Corner
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Sealant pulling away from one side of the joint
- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
Rented homes near Bourne End station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

External mastic in Littleworth Corner, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on façade panels, concrete & block and joints between brick and frames, and common reasons people get in touch are gaps where render, brick and frames meet and leaking joints around cladding and façade panels.
Around Littleworth Corner, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.
A one-year guarantee comes as standard, so you’re covered after we have gone.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check external joints each spring
- Get split or bare joints resealed while the damage is small
- Wash walls gently around the sealant
- Leave the joints unpainted unless we have said otherwise
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
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.
Your questions about external mastic in Littleworth Corner
Do you cover smaller places like Littleworth Corner?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Bourne End station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
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.
Do you work at height?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
How much does external mastic cost in Littleworth Corner?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.

What else we do in Littleworth Corner
What happens if it’s left?
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Around Littleworth Corner, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Outside joints around Littleworth Corner
With historic houses such as Cliveden (about 1.6 miles west) nearby, there’s older building stock in the area around Littleworth Corner 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.
For an older house near a landmark such as Church of St Anne, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Dropmore Infant School, larger buildings have long runs of movement joint that eventually need resealing.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Littleworth Corner 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.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
