About our external mastic in Burley
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We are often asked to deal with panel joints letting water in and weeds or debris growing in open joints, on façade panels, concrete & block and brickwork movement joints.
Somewhere as small as Burley, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Send us any details you have about the façade.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
What we can’t put right
New sealant can’t fix everything, and we’ll tell you before work begins. It won’t solve:
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Joints between brick and frames
- Façade panels
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
- Copings & trims
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Letting agents and landlords in Burley can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Why act early in Burley
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Around Burley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Walls and rooflines in Burley
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. With historic houses such as Avon Tyrrell House (about 2.3 miles south-west) nearby, there’s older building stock in the area around Burley as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Church of St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Burley Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Sway station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Burley: your questions answered
Do you work for landlords with property near Sway station?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you do external mastic in Burley?
Yes. We work across London and the South East, and Burley is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
When will the joints need doing again?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
- Make sure movement joints are not pointed over
- Deal with leaking gutters that soak the joints below
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Burley 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 look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
