About our external mastic in Weston Green
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 work on brickwork movement joints, concrete & block and copings & trims, and common reasons people get in touch are leaking joints around cladding and façade panels and weeds or debris growing in open joints.
Somewhere as small as Weston Green, 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.
A 12-month guarantee comes as standard, so you are covered after we have gone.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Render that’s blown, hollow or coming away
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Why act early in Weston Green
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Weston Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Weston Green buildings and the weather
With historic houses such as Hampton Court Palace (about 1.3 miles north) nearby, there’s older building stock in the area around Weston Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Esher College are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of All Saints include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Thames Ditton station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Weston Green is about 2 miles west of Surbiton, in Surrey. Weston Green gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Weston Green is one of 395 places in Surrey we cover. London is on our list too, around 13 miles away.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Point out the joints to other trades
- Leave the joints unpainted unless we’ve said otherwise
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
How the visit works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work starts. The work generally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Weston Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
Preparing for the visit
- Tell us about any water getting in
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Weston Green questions
Is Weston Green within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Weston Green in your area for external mastic?
Yes. Our work covers London and the South East, and Weston Green is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them.
How long will you be here?
A typical job takes a few hours to a few days, depending on the length of joint and the access. We’ll confirm how long when we quote.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
