How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Ask before painting over external sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.

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 generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Holme Green, 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 will 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

Outside joints around Holme Green

Managing a site like Floreat Montague Park Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Panel joints letting water in
- Movement joints filled with mortar instead of sealant

FAQs for Holme Green
Is Holme Green in your area for external mastic?
Yes, Holme Green is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is Holme Green within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Give us some details and we will confirm the access.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
- Render that is blown, hollow or coming away
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Concrete & block
- Joints between brick and frames

What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one.
