External mastic in Woolbeding
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on render & cladding joints, copings & trims and joints between brick and frames, and the jobs we see most are moss and dirt in joints with no sealant left and movement joints filled with mortar instead of sealant.
Around Woolbeding, 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.
Whatever the size of the job, it’s backed by our one-year guarantee in Woolbeding and across West Sussex.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.

Your questions about external mastic in Woolbeding
Is there a guarantee on external mastic in Woolbeding?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Woolbeding within the area you cover?
Yes. Woolbeding is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Signs you need external mastic in Woolbeding
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Signs it’s time to call us include:
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
- Rain getting behind render or cladding at a joint
If you live in an older home near The Parish Church of All Hollows, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Outside joints around Woolbeding
With historic houses such as Cowdray House (about 1.3 miles south-east) nearby, there’s older building stock in the area around Woolbeding as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
For site and facilities teams at buildings such as Stedham Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere as small as Woolbeding, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
- Façade panels
- Concrete & block
- Render & cladding joints
Why act early in Woolbeding
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Older cottages and farmhouses around Woolbeding can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
