About our external mastic in Lower Willingdon
On houses, flats and commercial buildings across Lower Willingdon, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We’re often asked to deal with sealant that has lost its bond to the brick or render and moss and dirt in joints with no sealant left, on render & cladding joints, brickwork movement joints and façade panels.
In and around Lower Willingdon, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
All our work is covered by a 12-month guarantee.

- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- When we can work, for business premises
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Lower Willingdon buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Alfriston Clergy House (about 4 miles west) are a reminder that the area around Lower Willingdon has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Polegate station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Willingdon Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Aftercare tips
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Keep movement joints as flexible joints, not mortar
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building. Parking around Lower Willingdon is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

What we’re called out for in Lower Willingdon
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Look out for any of the following:
- Sealant that has lost its bond to the brick or render
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
For an older house near a landmark such as St Wilfrid, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- Whether all the old sealant comes out first
- How long to leave it before use
- Whether the sealant suits the joint
- Is VAT in the price?
How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.
Landlord and commercial work in Lower Willingdon
If you manage several properties in or around Lower Willingdon, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and pictures by email help.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
