About our external mastic in Middle Barton
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. If you have weathered mastic that no longer stretches and water getting into walls through failed joints, we can help.
Somewhere as small as Middle Barton, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Why deal with it now?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. Older cottages and farmhouses around Middle Barton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits. We will give you a clear quote for the lot.

Do you need external mastic in Middle Barton?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
The problems people normally mention when they call are:
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
For landlords with property near Heyford station, split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
- Whether they’re fully insured
- What the quote includes, VAT included or not
Different surfaces, different methods
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
When it is not the sealant
In fairness, some problems need a different trade:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Joints between brick and frames
- Façade panels
- Concrete & block
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
Walls and rooflines in Middle Barton
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.
In the older streets around Church of St Edward the Confessor, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Middle Barton Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
