What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

How we handle external mastic in Great Bardfield
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. If you’re dealing with failed seals between different materials and damp patches traced to an open external joint, we can help, whatever the surface.
Older homes in small places like Great Bardfield may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Every job is covered by a 12-month guarantee, wherever you are in Essex.

Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What else we do in Great Bardfield
Great Bardfield buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Parish Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Great Bardfield Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Landlords, agents and businesses in Great Bardfield
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Great Bardfield, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why book with us
- Homes, businesses and hotels
- Trusted Arbo and Everbuild sealants
- White, clear, grey or another colour, product permitting
- 20+ years of sealant experience

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. For a village or hamlet like Great Bardfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- 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.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
