About our external mastic in Enborne
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. If you have water getting into walls through failed joints and sealant pulling away from one side of the joint, we can put it right, whatever the surface.
In a village or hamlet like Enborne, older cottages and farm buildings often stand in the open, 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.
Your job is guaranteed for a year, as with all our work.

Outside joints around Enborne
Historic houses like Benham Park (about 1.2 miles north) are a reminder that the area around Enborne 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. 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 an older house near a landmark such as Parish Church of St Michael, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Newbury station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Act on the first splits you see
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
- Failed render or damaged cladding panels
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Where we work in Enborne
- Render & cladding joints
- Copings & trims
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. In a small place like Enborne, 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.
- 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.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Tell us if parking is tricky

Common problems we fix in Enborne
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Most people get in touch when they notice one of these:
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Joints with sealant missing in places
Managing a site like Enborne C.E. Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- What guarantee comes with the work
- How much experience the applicator has
- What the quote includes, VAT included or not
- Whether the sealant suits the joint
Can I do it myself?
If you’re 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 fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
