I let a flat near Sittingbourne station. Can you help?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
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.
Are you insured?
Yes. We’re fully insured.
Where do you work from?
Mr Mastic is based in Crawley. We cover Bredgar and the rest of Kent, along with the rest of our area.
Will you leave a mess?

External mastic in Bredgar
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. We work on copings & trims, façade panels and joints between brick and frames, and common reasons people get in touch are sealant pulling away from one side of the joint and joints pointed up with cement by mistake.
Around Bredgar, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Bredgar buildings and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St John the Baptist, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Bredgar Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Sittingbourne station, split movement joints are easy to miss on a rental until damp shows inside.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Make sure movement joints aren’t pointed over
- Keep water from gutters off the wall
- Act on the first splits you see
- Check external joints each spring
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
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.

Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that is what we use, or one the system allows. Tell us what the building has when you get in touch.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere like Bredgar needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
