External & façade joints in Lucas Green, Surrey
Movement joints in Lucas Green need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.

External mastic in Lucas Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. If you are dealing with sealant pulling away from one side of the joint and panel joints letting water in, we can help.
Around Lucas Green, 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.
There’s a 12-month guarantee on every job, whatever its size.

Surface by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
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.
Signs you need external mastic in Lucas Green
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
The problems people usually mention when they call are:
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
Managing a site like Bisley CofE Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Lucas Green
Can you do external mastic in Lucas Green?
Yes, Lucas Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Will you come out to Lucas Green?
Yes. Lucas Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
When it is not the sealant
In fairness, some problems need a different trade:
- Failed render or damaged cladding panels
- Movement that is more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

External mastic in Lucas Green: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Brookwood station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Holy Trinity, an extension built onto an older house moves differently, and the joint between them takes the strain.

The process
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. For a village or hamlet like Lucas Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Advice
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Lucas Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
