External mastic in Great Saling, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you’re dealing with water getting into walls through failed joints and failed sealant between panels on a façade, we can put it right, whatever the surface.
Older homes in small places like Great Saling may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Point out the joints to other trades
- Get split or bare joints resealed while the damage is small
- Wash walls gently around the sealant
- Make sure movement joints aren’t pointed over
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Around Great Saling, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

What else we do in Great Saling
Different surfaces, different methods
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

Outside joints around Great Saling
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Braintree station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St James, older walls, gutters and the joints where extensions meet them need a flexible sealant.

We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.

Related advice
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
