Questions from Kearsney
Does the coastal weather in Kearsney affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
I let a flat near Kearsney station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
External mastic in Kearsney, done properly
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. We work on joints between brick and frames, façade panels and concrete & block, and common reasons people get in touch are sealant pulling away from one side of the joint and gaps where render, brick and frames meet.
Homes around Kearsney range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Whatever the size of the job, it’s backed by our one-year guarantee in Kearsney and across Kent.

The process
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a job in Kearsney, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Mention any parking rules near the property

Advice
How the job changes by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep high-pressure jets off the joints
- Point out the joints to other trades
- Check the sealant is paintable before painting near it
- Clear growth from the base of walls and joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What external mastic looks like in Kearsney
Kearsney is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Peter and St Paul include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Temple Ewell Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Kearsney is about 1 mile north-west of Dover, in Kent.

Signs you need external mastic in Kearsney
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Panel joints letting water in
Rented homes near Kearsney station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What happens if it’s left?
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. In an older home around Kearsney, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What affects the cost of external mastic
There’s no set price list, because jobs vary so much. What we look at:
- The product the joint needs
- How easy the joints are to reach
- How many areas need sealing
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
To help us quote quickly, let us know:
- Roughly how big the job is
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or drop us an email.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
