Do you need external mastic in Capel-le-Ferne?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
Common reasons people contact us are:
- Cracked joints where brick meets render or frames
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
- Joints pointed up with cement by mistake
For an older house near a landmark such as St Radigund, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- How the colour is chosen
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why

Why it’s worth doing now in Capel-le-Ferne
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. Older cottages and farmhouses around Capel-le-Ferne can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What external mastic looks like in Capel-le-Ferne
Capel-le-Ferne 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’s hard on movement joints and outside wall joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Folkestone Central station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Capel-le-Ferne Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Capel-le-Ferne questions
Will you come out to Capel-le-Ferne?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Folkestone Central station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall. If it has already been filled, we can generally cut it out and reseal it.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What the job involves on each surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
How to look after the new joints
So the new joints stay in good condition:
- Act on the first splits you see
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
- Ask before painting over external sealant
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. Earlier resealing means a smaller job and a better result.
How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Somewhere as small as Capel-le-Ferne, access is often the only tricky part. 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.
- We cut out the old mastic and rake out anything in the joint.
- 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.
Before we arrive
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
