About our external mastic in Warbleton
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. Common call-outs are for rigid filler in a joint that should flex and hard, crazed mastic that has stopped moving, across render & cladding joints, façade panels and brickwork movement joints.
Older homes in small places like Warbleton may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
So the new joints stay in good condition:
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

What affects the cost of external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Access and height
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job.
What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere like Warbleton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Advice
Signs you need external mastic in Warbleton
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
If you look after a building such as Heathfield Community College, its movement joints, gutters and trims need looking after like any other building’s.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Render that’s blown, hollow or coming away
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Outside joints around Warbleton
With historic houses such as Horselunges Manor (about 4 miles south) nearby, there’s older building stock in the area around Warbleton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near The Parish Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
