External & façade joints in Slinfold, West Sussex
Problem with your movement joints in Slinfold? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
- Panel joints letting water in
Honest limits
In fairness, there are a few things sealant won’t fix:
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint

External mastic in Slinfold, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We are often asked to deal with leaking joints around cladding and façade panels and joints where the bead has come unstuck, on joints between brick and frames, copings & trims and façade panels.
Older homes in small places like Slinfold may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

The process
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from a few hours to several days, depending on the building. In a small place like Slinfold, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Signs you need external mastic in Slinfold
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
If you can see any of these, it’s time to have the joints looked at:
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
Letting a property close to Christs Hospital station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- Whether the sealant suits the joint
- What insurance they hold
- How long to leave it before use
- How the joint is cleaned and prepared

Why it’s worth doing now in Slinfold
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Slinfold, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
Why book with us
- Neat joints and a tidy finish
- Arbo and Everbuild products
- You choose the colour before work begins
- Old sealant always removed completely

Walls and rooflines in Slinfold
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Slinfold CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around The Parish Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Surface by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
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. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
