External mastic for homes and businesses in Great Burstead
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include rain getting behind render or cladding at a joint and moss and dirt in joints with no sealant left, across façade panels, joints between brick and frames and copings & trims.
Somewhere as small as Great Burstead, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee.

How the job changes by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
External mastic in Great Burstead: local notes
With historic houses such as Ingatestone Hall (about 4.6 miles north-west) nearby, there’s older building stock in the area around Great Burstead as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as St Peter's Catholic Primary School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Billericay station? Then split movement joints are easy to miss on a rental until damp shows inside. Homes close to Church of St Mary Magdalene include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Your questions about external mastic in Great Burstead
Is Great Burstead in your area for external mastic?
Yes, Great Burstead is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Great Burstead?
Yes, Great Burstead is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
How long does external mastic take?
That depends on how much there is to do, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We’ll tell you when we quote.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Aftercare tips
Looking after new joints is easy:
- Show decorators and builders where the movement joints are
- Keep movement joints as flexible joints, not mortar
- Check external joints each spring
- Do not let climbing plants root in the sealant
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

What we do, step by step
When we get to you, 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. In a small place like Great Burstead, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Mention if the joints have been sealed before
