External & façade joints in Broxted, Essex
Our applicators work in Broxted on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Hard, crazed mastic that has stopped moving
- Plants rooting in failed movement joints
- Panel joints letting water in
Common problems we fix in Broxted
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Common reasons people contact us are:
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
Letting a property close to Stansted Airport station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic in Broxted, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we don’t skip that step. Typical jobs include moss and dirt in joints with no sealant left and cracked joints where brick meets render or frames, on joints between brick and frames, copings & trims and brickwork movement joints.
Older homes in small places like Broxted may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
Every job is covered by a one-year guarantee, wherever you are in Essex.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Look over the joints every year, ideally after winter
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed 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.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Broxted, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
How to prepare
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Mention if the joints have been sealed before
How to get a quote

External mastic in Broxted: local notes
With historic houses such as Horham Hall (about 1.4 miles north-east) nearby, there’s older building stock in the area around Broxted as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Mary the Virgin include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
Broxted is about 7 miles north-east of Bishop's Stortford, in Essex. From the centre of Broxted to the outskirts, we cover external mastic for every kind of property. Broxted is one of 644 places in Essex where we work for external mastic. You can also see our page for Chelmsford, roughly 15 miles from Broxted.
Every address in CM6 is within our area for external mastic, from the main roads to the quietest streets. If you need external mastic at a property on St Mary's Mews and Cranham Road or anywhere close by, we can help. We also cover the places around Broxted: Brick End (1 mile south), Henham (2 miles west), Debden Green (3 miles north), Fuller's End (3 miles west) and Elsenham (3 miles west). We also work in nearby towns such as Chelmsford (15 miles south-east), Braintree (12 miles east), Harlow (13 miles south-west), Saffron Walden (7 miles north), Halstead (15 miles east) and Great Dunmow (4 miles south-east).

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Broxted, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Common questions in Broxted
Do you cover smaller places like Broxted?
Yes, Broxted is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Stansted Airport station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
How we quote for external mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- The type of sealant required
- The number and length of the joints
- The number of rooms or windows
- Whether the work is at height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Helping us quote
There’s no need for technical detail. Just tell us:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- The address or postcode of the job
- The type of property
Need a quote? Please call 0345 464 0079 or drop us an email with a few details. We will explain what we’d do and give you a clear price before we start.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
