External & façade joints in Fishbourne, West Sussex
Problem with your movement joints in Fishbourne? We remove the old material, prepare the joints and seal them properly.
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
- Hard, crazed mastic that has stopped moving
When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Façade panels
- Copings & trims
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
External mastic for homes and businesses in Fishbourne
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Common call-outs are for water getting into walls through failed joints and brick movement joints where the sealant has split, on concrete & block, façade panels and joints between brick and frames.
Homes around Fishbourne range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
All of our work is guaranteed for twelve months.

When to call us in Fishbourne
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Signs it’s time to call us include:
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
If you let a flat or house near Fishbourne station, split movement joints are easy to miss on a rental until damp shows inside.

How we quote for external mastic
Your quote is based on your job. We look at:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- Whether there’s mould to deal with
- How many areas need sealing
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- The address or postcode of the job
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job and send photos if you have them.
Surface by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one before the bead.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Fishbourne: your questions answered
Do you work for landlords with property near Fishbourne station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Does living near the coast affect external mastic in Fishbourne?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
How much does external mastic cost in Fishbourne?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Keep water from gutters off the wall
- Make sure movement joints are not pointed over
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building, and the area is left clean. In a smaller place like Fishbourne, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Keep children and pets away from the work area

Walls and rooflines in Fishbourne
Fishbourne 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. With historic houses such as Goodwood House (about 3.9 miles north-east) nearby, there’s older building stock in the area around Fishbourne 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.
Schools such as Fishbourne CofE Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St Peter and St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.
