- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Sealant that has lost its bond to the brick or render
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Get split or bare joints resealed while the damage is small
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
- Make sure movement joints are not pointed over
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
External mastic for homes and businesses in Rodmell
For buildings in Rodmell, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Typical jobs include weeds or debris growing in open joints and sealant pulling away from one side of the joint, on façade panels, render & cladding joints and concrete & block.
Older homes in small places like Rodmell may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What we cannot put right
We’ll always be straight with you, so here’s what new sealant will not do:
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that’s more than a sealant joint can take
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

More services for Rodmell
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Common questions in Rodmell
Do you work for landlords with property near Southease station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will you come out to Rodmell?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
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. If it doesn’t work out, we can redo it.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Rodmell, along with the rest of our area.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
When to call us in Rodmell
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 can’t stretch and rips as the joint opens.
The most common problems we see are:
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Rigid filler in a joint that should flex
Schools such as Priory School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
External mastic in Rodmell: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Monk's House (about 0.4 miles north-east) nearby, there’s older building stock in the area around Rodmell as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Southease station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around St Peter's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

The process

We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. In a small place like Rodmell, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear the area around the work
- Mention any tricky access
- Mention if the joints have been sealed before
