External mastic for homes and businesses in Benington
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. Typical jobs include plants rooting in failed movement joints and failed sealant between panels on a façade, across render & cladding joints, copings & trims and façade panels.
Somewhere as small as Benington, 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.
Each job carries a 12-month guarantee, large or small.

Why act early in Benington
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. In a small place like Benington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What external mastic looks like in Benington
With historic houses such as Aston Bury (about 2 miles south-west) nearby, there’s older building stock in the area around Benington as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Watton-At-Stone station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Benington Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Parish Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain.

Related advice
Different surfaces, different methods
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Cracked brickwork or render that needs a builder or plasterer
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before you book.

Aftercare tips
A little care helps the new joints last. Our advice:
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
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.
