About our external mastic in Litlington
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 a rigid filler would soon crack. If you are dealing with weathered mastic that no longer stretches and brick movement joints where the sealant has split, we can put it right, on concrete & block, brickwork movement joints and copings & trims alike.
Older homes in small places like Litlington may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Litlington, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Litlington buildings and the weather
Litlington is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Alfriston School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Berwick (Sussex) station, split movement joints are easy to miss on a rental until damp shows inside.

Why deal with it now?
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Older cottages and farmhouses around Litlington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What you get with us
- We never seal over old sealant
- Colour agreed with you before any work starts
- An ARBOMaster approved applicator
- 20+ years of sealant experience
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Act on the first splits you see
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
- Look over the joints every year, ideally after winter
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Damp that is not coming from the joint
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Common problems we fix in Litlington
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The problems people usually mention when they call include:
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
- Panel joints letting water in
Homes close to The Parish Church of St Michael the Archangel include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
