External mastic in Hurstbourne Tarrant
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. We work on copings & trims, joints between brick and frames and concrete & block, and the jobs we see most are weeds or debris growing in open joints and water getting into walls through failed joints.
External sealant needs dry, clean surfaces, so work around Hurstbourne Tarrant is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, large or small.

Why act early in Hurstbourne Tarrant
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a small place like Hurstbourne Tarrant, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. The work usually takes anything from a few hours to several days, depending on the building. For a village or hamlet like Hurstbourne Tarrant, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Let us know about parking restrictions
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.

Signs you need external mastic in Hurstbourne Tarrant
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Look out for these signs:
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
If you look after a building such as Hurstbourne Tarrant Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- When the joint can take water or movement
- What product goes in the joint
- How long the guarantee is
- How the colour is chosen
What external mastic looks like in Hurstbourne Tarrant
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.
Rented homes near Andover station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before any work starts. It will not solve:
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work

Surfaces we seal
- Render & cladding joints
- Façade panels
- Concrete & block
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
How to look after the new joints
To keep the joints looking good and working properly:
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
