About our external mastic in Newland Green
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. If you have failed seals between different materials and sealant pulling away from one side of the joint, we can help, whatever the surface.
Somewhere as small as Newland Green, 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.

Newland Green buildings and the weather
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.
Schools such as Egerton Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of St James, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Different surfaces, different methods
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

How do I get a quote for external mastic in Newland Green?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us with a short description of the job.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on the building for a typical job. Somewhere like Newland Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Mention any tricky access

Related advice
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Older cottages and farmhouses around Newland Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why Newland Green clients choose us
- We never seal over old sealant

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Show decorators and builders where the movement joints are
- Make sure movement joints aren’t pointed over
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Should I try it myself first?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When to call us in Newland Green
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Keep an eye out for these signs:
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
If you let a flat or house near Pluckley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
