West Hill buildings and the weather
West Hill is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as St Paul's CofE Primary School and Nursery are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Galeed Strict Baptist Chapel, older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic in West Hill, done properly
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on brickwork movement joints, façade panels and copings & trims, and people most often call us about movement joints with cracked, split or missing sealant and joints where the bead has come unstuck.
Outbuildings, garages and conservatories around homes in places like West Hill add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a smaller place like West Hill, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- Any working-time requirements on site
- The number and length of the joints
- The old material and how stubborn it is
- Which sealant suits the joint
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
To make quoting easier, please include:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- A few photos by email, if you can
- Whether it has been sealed before
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we will take it from there.
FAQs for West Hill
Do you work for landlords with property near Brighton station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Will you come out to West Hill?
Yes, West Hill is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Are you fully insured?
Yes. We are fully insured for every job we do.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
How to look after the new joints
To keep the joints looking good and working properly:
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
- Keep high-pressure jets off the joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Around West Hill, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Signs you need external mastic in West Hill
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall and make things worse.
Any of these means the joints need attention:
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
Letting a property close to Brighton station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
- Damp that isn’t coming from the joint
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
