Lullington External Mastic
Our applicators work in Lullington on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Joints where the bead has come unstuck
What happens on the day
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access for a typical job. For a village or hamlet like Lullington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Clear the area around the work

Advice
External mastic for homes and businesses in Lullington
On houses, flats and commercial buildings across Lullington, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on façade panels, render & cladding joints and copings & trims, and people most often call us about rigid filler in a joint that should flex and cracked joints where brick meets render or frames.
Somewhere as small as Lullington, 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.
You get a 12-month guarantee, the same in Lullington as everywhere else we work.

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint

Outside joints around Lullington
Lullington 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. Historic houses like Alfriston Clergy House (about 0.3 miles north-west) are a reminder that the area around Lullington has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Church of St. Andrew, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Alfriston School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Berwick (Sussex) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Will you come out to Lullington?
Yes, Lullington is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is external mastic in a coastal place like Lullington any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.

We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Are you insured?
Yes, we are fully insured for every job we do.
How do I get a quote for external mastic in Lullington?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email and let us know what needs doing and where.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before the bead.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Don’t let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Have failed joints looked at early
- Keep water from gutters off the wall
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Working hours on commercial sites
- The number of rooms or windows
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Roughly how big the job is
- What’s wrong with the joints now
- The type of property
- Where the job is, and your postcode
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or send us an email.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
