About our external mastic in Flishinghurst
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on concrete & block, copings & trims and joints between brick and frames, and common reasons people get in touch are cracked joints where brick meets render or frames and movement joints filled with mortar instead of sealant.
Older homes in small places like Flishinghurst may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
All our work is covered by a one-year guarantee, wherever you are in Kent.

Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Point out the joints to other trades
- Check external joints each spring
- Act on the first splits you see
- Fix overflowing gutters above sealed joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
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.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Damp that isn’t coming from the joint
- Subsidence or other structural problems
- Adding movement joints to masonry that has none

Flishinghurst questions
Can you do external mastic in Flishinghurst?
Yes, Flishinghurst is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Marden station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
How much does external mastic cost in Flishinghurst?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
External mastic in Flishinghurst: local notes
With historic houses such as Scotney Castle (about 4.5 miles west) nearby, there’s older building stock in the area around Flishinghurst as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Colliers Green Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What we do, step by step
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. In a small place like Flishinghurst, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

Advice
What we are called out for in Flishinghurst
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Rain getting behind render or cladding at a joint
- Panel joints letting water in
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
If you let a flat or house near Marden station, split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- How the surfaces are prepared before sealing
- What guarantee comes with the work
- Are they insured?
- Whether the sealant suits the joint
