External mastic in Wickstreet: local notes
With historic houses such as Michelham Priory (about 1.2 miles east) nearby, there’s older building stock in the area around Wickstreet as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near The Parish Church of St Pancras, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Berwick (Sussex) station, split movement joints are easy to miss on a rental until damp shows inside.
Wickstreet is about 3 miles west of Hailsham, in East Sussex. Homes, rented property, offices and hotels in Wickstreet can book us for external mastic, old or new, large or small. The work is guaranteed for a year. 289 places in East Sussex are on our list. Brighton is on our list too, around 14 miles away.

External mastic in Wickstreet, done properly
For buildings in Wickstreet, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We’re often asked to deal with old sealant gone brittle and cracked and failed seals between different materials, across render & cladding joints, concrete & block and façade panels.
Around Wickstreet, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
All our work is covered by a one-year guarantee.

How we quote for external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- Which sealant suits the joint
- Access and height
- Mould in or behind the old joints
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- Pictures of the joints, sent by email
- Where the property is
- What’s wrong with the joints now
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.
Wickstreet questions
Do you cover Wickstreet for external mastic?
Yes. We work across London and the South East, and Wickstreet is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is Wickstreet within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before any work starts, matched as closely as the range allows.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
How do I get a quote for external mastic in Wickstreet?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
How it works
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Wickstreet, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Don’t let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Check external joints each spring
- Fix overflowing gutters above sealed joints
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.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
When it isn’t the sealant
It helps to know what we can’t do too:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Render that is blown, hollow or coming away
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Concrete & block
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
Do you need external mastic in Wickstreet?
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
People generally contact us when they notice one of these:
- Movement joints with cracked, split or missing sealant
- Sealant that has lost its bond to the brick or render
- Joints pointed up with cement by mistake
- Panel joints letting water in
For site and facilities teams at buildings such as Bede's Prep School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
