Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
External mastic in Abbots Worthy, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. Common call-outs are for weeds or debris growing in open joints and brick movement joints where the sealant has split, across brickwork movement joints, joints between brick and frames and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Abbots Worthy is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and protects the render itself.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep high-pressure jets off the joints
- Deal with leaking gutters that soak the joints below
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
DIY versus a professional finish
If you are 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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

When to call us in Abbots Worthy
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
The problems people generally mention when they call include:
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
For an older house near a landmark such as Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Abbots Worthy, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs 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
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
