External & façade joints in Mashbury, Essex
Problem with your movement joints in Mashbury? We cut out the old, prepare the joints and apply the right sealant.
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
External mastic in Mashbury
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you have cracked joints where brick meets render or frames and rain getting behind render or cladding at a joint, we can help.
Somewhere as small as Mashbury, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Brickwork movement joints

- Render & cladding joints
When to call us in Mashbury
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Any of these means the joints need attention:
- Joints with sealant missing in places
- Plants rooting in failed movement joints
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
Homes close to Mashbury Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- When the joint can take water or movement
- Whether VAT is included
- What happens if the job turns out different
- What guarantee comes with the work
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Outside joints around Mashbury
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.
For landlords with property near Chelmsford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
FAQs for Mashbury
Do you cover smaller places like Mashbury?
Yes. Mashbury is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Chelmsford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Are you fully insured?
Yes. We are fully insured.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
How we quote for external mastic
You’ll get a clear quote before any work starts. It’s based on:
- Any working-time requirements on site
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Where the property is
- Whether it’s a home or a business
There’s no standard price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.
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 for a handful of joints, longer for a whole elevation from start to finish. Somewhere like Mashbury needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
Getting a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
