External & façade joints in Stocks Green, Essex
Our applicators work in Stocks Green on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Rain getting behind render or cladding at a joint
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
- Concrete & block
- Joints between brick and frames
- Façade panels
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
External mastic in Stocks Green
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you have brick movement joints where the sealant has split and gaps where render, brick and frames meet, we can put it right, on render & cladding joints, concrete & block and brickwork movement joints alike.
External sealant needs dry, clean surfaces, so work around Stocks Green is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Every job is covered by our 12-month guarantee.

Surface by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
External mastic in Stocks Green: local notes
Historic houses like Layer Marney Tower (about 4 miles south-east) are a reminder that the area around Stocks Green has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Kelvedon station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Parish Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why deal with it now?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Older cottages and farmhouses around Stocks Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What affects the cost of external mastic
Jobs vary more than people expect. The main factors:
- Any mould that needs treating
- The number of rooms or windows
- Which sealant suits the joint
- Any working-time requirements on site
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- What’s wrong with the joints now
- A few pictures by email, if you can
- Where the property is
Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll take it from there.
Work for landlords, hotels and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
When to call us in Stocks Green
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.
Most people get in touch when they notice one of these:
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
If you look after a building such as Feering Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- Are they insured?
- How the colour is chosen
- How hidden problems are handled
- Who does the work, and how experienced they are

Common questions in Stocks Green
Do you work for landlords with property near Kelvedon station?

Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
