Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
How we handle external mastic in Ashbank
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, copings & trims and render & cladding joints, and people most often call us about gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving.
Somewhere as small as Ashbank, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
All our work is covered by our 12-month guarantee.

External mastic in Ashbank: local notes
Historic houses like Leeds Castle (about 0.6 miles east) are a reminder that the area around Ashbank has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Hollingbourne station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Homes close to St Nicholas's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Leeds and Broomfield Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Keeping the joints in good condition
Looking after new joints is easy:
- Don’t let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
