External mastic in Chattenden, done properly
On houses, flats and commercial buildings across Chattenden, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you have panel joints letting water in and joints where the bead has come unstuck, we can help, on concrete & block, façade panels and copings & trims alike.
Around Chattenden, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Every job is covered by our 12-month guarantee, wherever you are in Medway.

Common problems we fix in Chattenden
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Failed seals between different materials
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
In the older streets around Bishop Gundulph Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
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.
External mastic in Chattenden: local notes
Chattenden is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Restoration House (about 2.6 miles south-west) are a reminder that the area around Chattenden has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as Chattenden Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Strood station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

What affects the quote in Chattenden
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with

The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.

- The address or postcode of the job

Every job is quoted individually. Just ring 0345 464 0079 or send us an email with the details, and photos are welcome.
How the visit works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. For a village or hamlet like Chattenden, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Chattenden: your questions answered
Do you cover smaller places like Chattenden?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is external mastic in a coastal place like Chattenden any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep soil, plants and ivy away from the joints
- Deal with leaking gutters that soak the joints below
- Look over the joints every year, ideally after winter
- Have failed joints looked at early
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for property managers and facilities teams in Chattenden and across Medway. We can quote a run of properties together, and we’re fully insured.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. 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.
