External & façade joints in Lower Green, Essex
We cover Lower Green for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Plants rooting in failed movement joints
- Joints pointed up with cement by mistake
- Leaking joints around cladding and façade panels
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How we handle external mastic in Lower Green
Low-level joints can usually 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 concrete & block, façade panels and joints between brick and frames, and common reasons people get in touch are plants rooting in failed movement joints and damp patches traced to an open external joint.
Around Lower Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
A one-year guarantee comes with the work, just as it does everywhere we cover.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

External mastic in Lower Green: local notes

How we quote for external mastic
The quote reflects the job in front of us. We look at:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The product the joint needs
- The number and length of the joints
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How we’d reach the joints
- If someone has resealed it before
- How many joints, rooms or windows are involved
- The problem you’ve noticed
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
What happens on the day
On the day, there’s very little for you to do. 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. In a small place like Lower Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us about any water getting in
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
Ask for a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

More services for Lower Green
Do you need external mastic in Lower Green?
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
In the older streets around Church of St John the Evangelist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Lower Green: your questions answered
Can you do external mastic in Lower Green?
Yes. Our work covers London and the South East, and Lower Green is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Is Lower Green within the area you cover?
Yes, Lower Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
How much does external mastic cost in Lower Green?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and let us know what needs doing and where.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Around Lower Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
