- Movement joints filled with mortar instead of sealant

- Brick movement joints where the sealant has split
How to look after the new joints
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Leave the joints unpainted unless we’ve said otherwise
- Keep water from gutters off the wall
- Look over the joints every year, ideally after winter
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Curdridge, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

What else we do in Curdridge
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How we quote for external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Access and height
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
To make quoting easier, please include:
- The type of property
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Whether it has been sealed before

What we can’t put right
We won’t take on work that will not last, so these are the limits:

- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Concrete & block
- Copings & trims

What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
What should I tell you?
Tell us what needs doing and where. If we need more, we will ask.
Do you work at height?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.

Common problems we fix in Curdridge
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
For site and facilities teams at buildings such as Curdridge Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Outside joints around Curdridge
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Botley station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain.
