External & façade joints in Leigh, Surrey
Movement joints in Leigh need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Water getting into walls through failed joints
- Brick movement joints where the sealant has split
- Failed seals between different materials
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How we handle external mastic in Leigh
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on façade panels, brickwork movement joints and copings & trims, and common reasons people get in touch are cracked joints where brick meets render or frames and damp patches traced to an open external joint.
In a village or hamlet like Leigh, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
You get a one-year guarantee, the same in Leigh as everywhere else we work.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. Somewhere like Leigh needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Tell us if parking is tricky

Outside joints around Leigh
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Burys Court School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Betchworth station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of St Bartholomew include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Surface by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
When something else is needed
We will always be straight with you, so here’s what sealant cannot fix:
- Movement that is more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Concrete & block
- Joints between brick and frames
- Façade panels
- Brickwork movement joints
- Render & cladding joints
- Copings & trims

Quotes for external mastic in Leigh
Jobs vary more than people expect. What affects the quote:
- The amount of work
- The product the joint needs
- Any working-time requirements on site
- Whether there’s mould to deal with
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Photos by email, if that is easy
- The rough size of the job
- Access, such as stairs, a lift or height
- The address or postcode of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Fix overflowing gutters above sealed joints
- Keep high-pressure jets off the joints
- Don’t let climbing plants root in the sealant
- Leave the joints unpainted unless we have said otherwise
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
