We cover Burgh Heath for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.

External mastic in Burgh Heath, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We’re often asked to deal with old sealant gone brittle and cracked and gaps where render, brick and frames meet, on concrete & block, façade panels and render & cladding joints.
Around Burgh Heath, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job, whatever its size.

Walls and rooflines in Burgh Heath
Historic houses like Fitznells Manor (about 3.4 miles north-west) are a reminder that the area around Burgh Heath 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Kingswood station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to St Mary's include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

The closest station to Burgh Heath is Kingswood station, about 1 mile south of the centre. A little further out are The Ashley Centre (2.8 miles north-west) and Walton on the Hill (2.3 miles south-west). For a walk, there’s Colley Hill and Cuddington Meadows.
Why act early in Burgh Heath
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Older cottages and farmhouses around Burgh Heath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

When to call us in Burgh Heath
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Common reasons people contact us include:
- Sealant pulling away from one side of the joint
- Failed sealant between panels on a façade
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
For site and facilities teams at buildings such as Aberdour School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Whether they seal over old material or remove it
- Whether you can choose the colour
- How much experience the applicator has
- The length of the guarantee
Your questions about external mastic in Burgh Heath
Do you cover smaller places like Burgh Heath?
Yes, Burgh Heath is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Kingswood station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
- Do not let climbing plants root in the sealant
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.

What else we do in Burgh Heath
What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Burgh Heath, the journey is planned in advance: 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.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Related advice
What the job involves on each surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How we quote for external mastic
You’ll get a clear quote before any work starts. It’s based on:

- How many areas need sealing
