Hunters Forstal External Mastic
We cover Hunters Forstal for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Failed seals between different materials
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake
External mastic in Hunters Forstal
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. If you are dealing with movement joints filled with mortar instead of sealant and sealant pulling away from one side of the joint, we can help, whatever the surface.
In a village or hamlet like Hunters Forstal, older cottages and farm buildings often stand in the open, 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.

Questions from Hunters Forstal
Will you come out to Hunters Forstal?
Yes, Hunters Forstal is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect external mastic in Hunters Forstal?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Do you use backing rod?
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.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Will the new joint stand out?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Can I do it myself?
If you do try it yourself, take your time over the 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. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Do you need external mastic in Hunters Forstal?
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Signs it’s time to call us include:
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
If you look after a building such as Herne Church of England Infant School, its movement joints, gutters and trims need looking after like any other building’s.

What the job involves on each surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. Somewhere as small as Hunters Forstal, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any tricky access
- Clear items away from the joints we are working on
- Mention any parking rules near the property

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we will tell you before work begins. It won’t solve:
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

Hunters Forstal buildings and the weather
Hunters Forstal is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Bartholomew, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Herne Bay station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
