External mastic in Clanville, done properly
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you are dealing with sealant pulling away from one side of the joint and joints pointed up with cement by mistake, we can put it right, on brickwork movement joints, façade panels and copings & trims alike.
External sealant needs dry, clean surfaces, so work around Clanville is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, you get the same one-year guarantee in Clanville and across Hampshire.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. For a village or hamlet like Clanville, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
How to prepare
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Keeping the joints in good condition
So the new joints stay in good condition:
- Don’t let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
Different surfaces, different methods
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.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Clanville buildings and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Appleshaw St Peter's CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Andover station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

- The type of property
- A few pictures by email, if you can
- Access, such as stairs, a lift or height

Common problems we fix in Clanville
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Signs it’s time to call us include:
- Rain getting behind render or cladding at a joint
- Panel joints letting water in
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
In the older streets around St Margaret's Chapel, an extension built onto an older house moves differently, and the joint between them takes the strain.
