Horndon on the Hill External Mastic
Problem with your movement joints in Horndon on the Hill? We cut out the old, prepare the joints and apply the right sealant.
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
Different surfaces, different methods
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
About our external mastic in Horndon on the Hill
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it.

External sealant needs dry, clean surfaces, so work around Horndon on the Hill is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.

Horndon on the Hill: your questions answered
I let a flat near Stanford-Le-Hope station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Horndon on the Hill?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll say how long yours will take.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What happens on the day
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building. Somewhere as small as Horndon on the Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Advice
External mastic in Horndon on the Hill: local notes
Horndon on the Hill is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Stanford-Le-Hope station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Horndon-On-the-Hill CofE Primary School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Peter and St Paul include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Show decorators and builders where the movement joints are
- Keep soil, plants and ivy away from the joints
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
What affects the quote in Horndon on the Hill
Jobs vary more than people expect. What affects the quote:
- How much there is to do
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a small place like Horndon on the Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
