When to call us in Newney Green
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
These are the problems we are asked about most:
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
Managing a site like Hylands School? Then its movement joints, gutters and trims need looking after like any other building’s.

About our external mastic in Newney Green
For buildings in Newney Green, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We’re often asked to deal with failed seals between different materials and weathered mastic that no longer stretches, across joints between brick and frames, concrete & block and brickwork movement joints.
Somewhere as small as Newney Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Newney Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

How we quote for external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- How easy the joints are to reach
- How many rooms, windows or areas are involved
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or send us an email.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Questions from Newney Green
Is Newney Green within the area you cover?
Yes. Newney Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Chelmsford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
How do I get a quote for external mastic in Newney Green?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
External mastic in Newney Green: local notes
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. Historic houses like Hylands (about 2.7 miles south-east) are a reminder that the area around Newney Green 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.
For an older house near a landmark such as Church of St Michael and All Angels, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Chelmsford station? Then split movement joints are easy to miss on a rental until damp shows inside.

- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
