When to call us in Framfield
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
It’s worth asking for a quote if you see:
- Joints with sealant missing in places
- Panel joints letting water in
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
Letting a property close to Uckfield station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- How long the guarantee is
- What insurance they hold

About our external mastic in Framfield
For buildings in Framfield, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have cracked joints where brick meets render or frames and movement joints filled with mortar instead of sealant, we can put it right, on concrete & block, render & cladding joints and façade panels alike.
Older homes in small places like Framfield may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Big or small, it’s backed by our 12-month guarantee in Framfield and across East Sussex.

What external mastic looks like in Framfield
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.
Homes close to St Thomas à Becket Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Framfield Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Surface by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Keeping the joints in good condition
Aftercare is simple:
- Do not let climbing plants root in the sealant
- Act on the first splits you see
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
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 it’s worth resealing at the first signs.
The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Somewhere as small as Framfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How long does external mastic take?
That depends on how much there is to do, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
When it isn’t the sealant
Before you book, it’s worth knowing the limits:
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
