External mastic for Awbridge and the surrounding area: careful preparation, the right product and tidy work. Ask us for a quick quote.
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
External mastic in Awbridge, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you have moss and dirt in joints with no sealant left and movement joints filled with mortar instead of sealant, we can help, whatever the surface.
Somewhere as small as Awbridge, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Awbridge, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Rising or penetrating damp from elsewhere in the wall
- Render that’s blown, hollow or coming away
- Movement that is more than a sealant joint can take
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Façade panels
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
Why act early in Awbridge
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. In a small place like Awbridge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Outside joints around Awbridge
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Mottisfont Abbey (about 2 miles north) are a reminder that the area around Awbridge 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.
For an older house near a landmark such as Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Awbridge Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Mottisfont & Dunbridge station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Aftercare tips
After the cure time, these simple habits help:
- Show decorators and builders where the movement joints are
- Clear growth from the base of walls and joints
- Check external joints each spring
- Get split or bare joints resealed while the damage is small
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
