About our external mastic in Norlington
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you have gaps where render, brick and frames meet and moss and dirt in joints with no sealant left, we can help, on copings & trims, brickwork movement joints and façade panels alike.
Somewhere as small as Norlington, homes and farm buildings often face open ground, 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.
Whatever the size of the job, you get the same one-year guarantee in Norlington and across East Sussex.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
- Render that is blown, hollow or coming away
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Façade panels

Leave it or put it right?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Norlington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What external mastic looks like in Norlington
Historic houses like Glyndebourne (about 1.6 miles south) are a reminder that the area around Norlington 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Ringmer Community College and Sixth Form are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Lewes station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to The Parish Church of St Mary the Virgin include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
