What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Minsted needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs 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
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

External mastic in Minsted, done properly
For buildings in Minsted, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We’re often asked to deal with rain getting behind render or cladding at a joint and panel joints letting water in, on concrete & block, brickwork movement joints and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Minsted is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Honest limits
In fairness, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Render that is blown, hollow or coming away
- Movement that’s more than a sealant joint can take
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Concrete & block
Why it’s worth doing now in Minsted
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Older cottages and farmhouses around Minsted can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- An ARBOMaster approved applicator

Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before sealing.
Do you need external mastic in Minsted?
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Failed sealant between panels on a façade
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
If you look after a building such as Stedham Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include

- How the surfaces are prepared before sealing

What external mastic looks like in Minsted
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Cowdray House (about 2.1 miles east) nearby, there’s older building stock in the area around Minsted as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near The Parish Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can I do it myself?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
