External mastic in Great Bentley, done properly
A movement joint is only as good as its depth. 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. Common call-outs are for sealant pulling away from one side of the joint and joints with sealant missing in places, across concrete & block, brickwork movement joints and joints between brick and frames.
In and around Great Bentley, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.

Looking after it afterwards
After the cure time, these simple habits help:
- Avoid pressure-washing directly into sealant joints
- Point out the joints to other trades
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we have said otherwise
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
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 fails, we can still redo it.
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Questions from Great Bentley
Do you work for landlords with property near Great Bentley station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will you come out to Great Bentley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How do I get a quote for external mastic in Great Bentley?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
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.
What is backing rod for?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In an older home around Great Bentley, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Walls and rooflines in Great Bentley
Historic houses like Thorpe Hall (about 4.4 miles east) are a reminder that the area around Great Bentley has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Great Bentley Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Related advice
Do you need external mastic in Great Bentley?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Keep an eye out for these signs:
- Failed sealant between panels on a façade
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
Rented homes near Great Bentley station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
