The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Fordcombe, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

Related advice
External mastic for homes and businesses in Fordcombe
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you have gaps where render, brick and frames meet and movement joints with cracked, split or missing sealant, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Fordcombe is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, large or small.

How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant is not too deep.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not 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.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Concrete & block
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Where a wall is exposed, as many are in small places like Fordcombe, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Questions from Fordcombe
Do you cover smaller places like Fordcombe?
Yes, we do. 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.

Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
What is backing rod for?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.

Fordcombe buildings and the weather
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. With historic houses such as Groombridge Place (about 1.8 miles south) nearby, there’s older building stock in the area around Fordcombe as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St Peter include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Fordcombe Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

What we’re called out for in Fordcombe
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
For landlords with property near Ashurst Kent station, outside joints that have cracked can let damp into a rental, so check them between lets.
