About our external mastic in Chilton Foliat
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on concrete & block, brickwork movement joints and copings & trims, and people most often call us about hard, crazed mastic that has stopped moving and gaps where render, brick and frames meet.
External sealant needs dry, clean surfaces, so work around Chilton Foliat is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes as standard, so you are covered after we have gone.

What external mastic looks like in Chilton Foliat
Historic houses like Ramsbury Manor (about 4 miles west) are a reminder that the area around Chilton Foliat has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Chilton Foliat Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions from Chilton Foliat
Is Chilton Foliat within the area you cover?
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.
Can you do external mastic in Chilton Foliat?
Yes. We work across London and the South East, and Chilton Foliat is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.

- Failed render or damaged cladding panels
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

The process
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Chilton Foliat needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any tricky access
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Related advice
Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant isn’t too deep.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
When to call us in Chilton Foliat
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
Signs it’s time to call us include:
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
Rented homes near Hungerford station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
Keeping the joints in good condition
So the new joints stay in good condition:
- Act on the first splits you see
- Do not let climbing plants root in the sealant
- Leave the joints unpainted unless we have said otherwise
- Deal with leaking gutters that soak the joints below
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In a small place like Chilton Foliat, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
