External mastic in West Kingston
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. If you’re dealing with moss and dirt in joints with no sealant left and water getting into walls through failed joints, we can put it right, on brickwork movement joints, façade panels and render & cladding joints alike.
Somewhere as small as West Kingston, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
A 12-month guarantee comes as standard.

What affects the quote in West Kingston
Call for a quick quote. The main things that affect it are:
- Any mould that needs treating
- When we can work, for business premises
- How much there is to do
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- How we’d reach the joints
- The type of property
- Pictures of the joints, sent by email
- Where the property is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Looking after it afterwards
Aftercare is simple:
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Why act early in West Kingston
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like West Kingston, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why book with us
- Colour agreed with you before work begins
- Any old sealant cut out fully, not covered over
- A 12-month guarantee on all work
- A sealant colour to suit the surroundings
Common problems we fix in West Kingston
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The problems people normally mention when they call include:
- Sealant pulling away from one side of the joint
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
If you let a flat or house near Angmering station, outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- How hidden problems are handled
- How the surfaces are prepared before sealing
- How long to leave it before use
- Who turns up on the day

West Kingston buildings and the weather
West Kingston is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Ecclesden Manor (about 1.7 miles north) nearby, there’s older building stock in the area around West Kingston as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like East Preston Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around St Andrew's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Your questions about external mastic in West Kingston
Is external mastic in a coastal place like West Kingston any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Angmering station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, wherever you are.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
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.
Are you insured?
Yes. Full insurance covers our work.
The process
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. In a small place like West Kingston, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
