We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. If you have failed seals between different materials and joints pointed up with cement by mistake, we can help, whatever the surface.

Walls and rooflines in Eight Ash Green
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Holy Trinity CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near All Saints Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Tell anyone working on the walls about the movement joints
- Ask before painting over external sealant
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
What sealant work can’t fix
It helps to know what we cannot do too:
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Joints between brick and frames
- Copings & trims
- Façade panels
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Common problems we fix in Eight Ash Green
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
If you can see any of these, it’s time to have the joints looked at:
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
For landlords with property near Marks Tey station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How it works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. For a village or hamlet like Eight Ash Green, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
