External mastic in Nettlestead Green, done properly
For buildings in Nettlestead Green, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Common call-outs are for brick movement joints where the sealant has split and damp patches traced to an open external joint, across copings & trims, façade panels and render & cladding joints.
In a village or hamlet like Nettlestead Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
What the job involves on each surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Nettlestead Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can

- Let us know if you’ve seen damp or leaks

External mastic in Nettlestead Green: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Old Soar Manor (about 4.3 miles north-west) are a reminder that the area around Nettlestead Green 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.
Rented homes near Yalding station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as St Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Looking after it afterwards
Aftercare is simple:
- Avoid pressure-washing directly into sealant joints
- Point out the joints to other trades
- Have failed joints looked at early
- Check the sealant is paintable before painting near it
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Nettlestead Green questions
Do you work for landlords with property near Yalding station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is Nettlestead Green within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
What affects the cost of external mastic
The price is agreed before any work begins. It takes into account:
- Access and height
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- How many areas need sealing
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- If someone has resealed it before
