Surface by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
About our external mastic in Little Holbury
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. We work on concrete & block, copings & trims and render & cladding joints, and common reasons people get in touch are joints with sealant missing in places and leaking joints around cladding and façade panels.
External sealant needs dry, clean surfaces, so work around Little Holbury is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Your job is guaranteed for a year, as with all our work.

External mastic in Little Holbury: local notes
Little Holbury is within about 2 miles of 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. 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.
For site and facilities teams at buildings such as Manor Church of England Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Historic houses such as Beaulieu Palace House, about 2.8 miles west, show how far back building around Little Holbury goes.

Little Holbury: your questions answered
Does the coastal weather in Little Holbury affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Is Little Holbury within the area you cover?
Yes. Little Holbury is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. In a small place like Little Holbury, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

What we are called out for in Little Holbury
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Any of these means the joints need attention:
- Rigid filler in a joint that should flex
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Damp patches traced to an open external joint
If you let a flat or house near Netley station, outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- What product goes in the joint
- Are they insured?
- Which colour the sealant will be
- Is VAT in the price?
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Wash walls gently around the sealant
- Point out the joints to other trades
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
