External mastic in Ashley
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you’re dealing with weeds or debris growing in open joints and sealant that has lost its bond to the brick or render, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Ashley is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Our work is backed for twelve months.

Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation from start to finish. In a small place like Ashley, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts

Honest limits
In fairness, there are a few things sealant won’t fix:
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Where we work in Ashley
- Copings & trims
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What affects the quote in Ashley
We quote each job individually. This is what makes a difference:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Mould in or behind the old joints
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- What’s wrong with the joints now
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
Your questions about external mastic in Ashley
Is Ashley within the area you cover?
Yes. Ashley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Ashley in your area for external mastic?
Yes. We work across London and the South East, and Ashley is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before any work starts.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Around Ashley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Walls and rooflines in Ashley
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Walmer Castle (about 4.3 miles east) are a reminder that the area around Ashley has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Martin Mill station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around East Studdal Church Hall, an extension built onto an older house moves differently, and the joint between them takes the strain.
