Chickney External Mastic
Movement joints in Chickney need attention? We cut out the old, prepare the joints and apply the right sealant.
- Sealant that has lost its bond to the brick or render
- Cracked joints where brick meets render or frames
- Joints with sealant missing in places
External mastic in Chickney
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have failed seals between different materials and brick movement joints where the sealant has split, we can help.
Outside joints can only be sealed when they’re dry, so work in Chickney 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, and the guarantee is the same wherever you are.

What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Get split or bare joints resealed while the damage is small
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

Questions from Chickney
Will you come out to Chickney?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Chickney in your area for external mastic?
Yes, Chickney is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Chickney buildings and the weather
With historic houses such as Horham Hall (about 1.7 miles north) nearby, there’s older building stock in the area around Chickney as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For an older house near a landmark such as Church of St Mary the Virgin, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Stansted Airport station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

What affects the cost of external mastic
Your quote is based on your job. We take into account:
- The number and length of the joints
- The old material and how stubborn it is
- How easy the joints are to reach
- Which sealant suits the joint
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- The rough size of the job
- What’s wrong with the joints now
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details, and pictures are welcome.
Should I try it myself first?
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. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. For a village or hamlet like Chickney, 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.
- 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.
Before we arrive
- Let us know about parking restrictions
- Clear the area around the work
- Let us know if you’ve seen damp or leaks

Why deal with it now?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together. Where a wall is exposed, as many are in small places like Chickney, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
