- Joints where the bead has come unstuck
How we handle external mastic in Hale Green
A movement joint is only as good as its depth. 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 hard, crazed mastic that has stopped moving and joints where the bead has come unstuck, we can help, on concrete & block, joints between brick and frames and copings & trims alike.
External sealant needs dry, clean surfaces, so work around Hale Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You get a 12-month guarantee, the same in Hale Green as everywhere else we work.

What the job involves on each surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep high-pressure jets off the joints
- Tell anyone working on the walls about the movement joints
- Ask before painting over external sealant
- Clear growth from the base of walls and joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Once a joint cannot move, the wall finds another way, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

When to call us in Hale Green
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
The problems people usually mention when they call are:
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
- Failed seals between different materials
- Sealant pulling away from one side of the joint
In the older streets around The Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How we quote for external mastic
Jobs vary more than people expect. The main factors:
- The number and length of the joints
- The type of sealant required

- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own, so start by telling us what you need. Just ring 0345 464 0079 or email us with the details, and photos are welcome.

Walls and rooflines in Hale Green
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Horselunges Manor (about 2.4 miles south-east) are a reminder that the area around Hale Green has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Chiddingly Primary School, its movement joints, gutters and trims need looking after like any other building’s.

The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Hale 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’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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Leave it or put it right?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Older cottages and farmhouses around Hale Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
