External mastic in Elstead
A movement joint is a deliberate break that lets a wall expand and contract. 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. If you have cracked joints where brick meets render or frames and old sealant gone brittle and cracked, we can put it right, whatever the surface.
Homes around Elstead range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Looking after it afterwards
After the cure time, these simple habits help:
- Clear growth from the base of walls and joints
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
- Ask before painting over external sealant
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Once a joint cannot move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
What happens if it’s left?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a smaller place like Elstead, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Structural movement, which needs a surveyor or engineer
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall

Your questions about external mastic in Elstead
Can you help a landlord with a rental near Milford (Surrey) station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is Elstead in your area for external mastic?
Yes. We work across London and the South East, and Elstead is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months.
Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Walls and rooflines in Elstead
Historic houses like Wanborough Manor (about 3.7 miles north-east) are a reminder that the area around Elstead 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Milford (Surrey) station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as St James CofE Aided Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What affects the cost of external mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- Mould in or behind the old joints
- The old material and how stubborn it is
- Access and height
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access. Parking around Elstead is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
