External mastic for homes and businesses in Wood's Corner
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you are dealing with brick movement joints where the sealant has split and movement joints filled with mortar instead of sealant, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Wood's Corner is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Each job carries a 12-month guarantee, large or small.

Is Wood's Corner within the area you cover?

What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you have insurance?
Yes. Full insurance covers our work.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.

What we are called out for in Wood's Corner
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Most people get in touch after spotting something like this:
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
- Weeds or debris growing in open joints
Rented homes near Stonegate station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

External mastic in Wood's Corner: local notes
Historic houses like Bateman's (about 2.9 miles north) are a reminder that the area around Wood's Corner 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to The Parish Church of St Giles include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Dallington Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Why act early in Wood's Corner
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. Around Wood's Corner, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

How the job changes by surface
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Looking after it afterwards
Aftercare is simple:
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
What happens on the day
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. For a village or hamlet like Wood's Corner, the journey is planned in advance: 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 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
