The process

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Norton Ash, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. Old sealant and any debris are cut and raked out.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height
  • Mention if the joints have been sealed before

How we handle external mastic in Norton Ash

Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. Common call-outs are for brick movement joints where the sealant has split and panel joints letting water in, on copings & trims, concrete & block and façade panels.

In a village or hamlet like Norton Ash, older cottages and farm buildings often stand in the open, 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.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Norton Ash: your questions answered

Can you help a landlord with a rental near Teynham station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Is external mastic in a coastal place like Norton Ash any different?

Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Do you cover Norton Ash?

Yes. We are based in Crawley and work across South East England, London and Scotland, Norton Ash included.

What colours does the sealant come in?

We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Do you work at height?

It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.

How do I get a quote for external mastic in Norton Ash?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

How to look after the new joints

So the new joints stay in good condition:

  • Check the sealant is paintable before painting near it
  • Keep movement joints as flexible joints, not mortar
  • Walk round the building once a year and look at the joints
  • Have failed joints looked at early

Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.

Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

What we can’t put right

New sealant cannot fix everything, and we’ll tell you before work begins. It won’t solve:

  • Walls that need new movement joints cut into them
  • Loose or hollow render, which needs re-rendering
  • Movement that is more than a sealant joint can take

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Where we work in Norton Ash

  • Façade panels
  • Render & cladding joints
  • Copings & trims
  • Concrete & block
  • Joints between brick and frames
  • Brickwork movement joints

What we are called out for in Norton Ash

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.

Most people get in touch after spotting one of these:

  • Joints pointed up with cement by mistake
  • Joints with sealant missing in places
  • Rain getting behind render or cladding at a joint
  • Weathered mastic that no longer stretches

If you let a flat or house near Teynham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

10 questions to ask before booking

DIY versus a professional finish

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.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What the job involves on each surface

Copings and trims

Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.

Render joints

Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.

What external mastic looks like in Norton Ash

Norton Ash is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you look after a building such as Teynham Parochial Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
