The process

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes anything from a few hours to several days, depending on the building. For a village or hamlet like Herne Common, 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. We cut out the failed sealant and rake out any dirt or growth.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Preparing for the visit

  • Clear the area around the work
  • Keep pets and children clear of the area while we work
  • Where the joints are inside, avoid wetting them before we arrive

Advice

About our external mastic in Herne Common

Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. Common call-outs are for joints pointed up with cement by mistake and weathered mastic that no longer stretches, across brickwork movement joints, joints between brick and frames and façade panels.

Around Herne Common, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

All of our work is guaranteed for twelve months.

How to look after the new joints

A little care helps the new joints last. Our advice:

  • Check external joints each spring
  • Clear growth from the base of walls and joints
  • Keep water from gutters off the wall
  • Have failed joints looked at early

Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

Herne Common questions

Do you work for landlords with property near Herne Bay station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Is Herne Common within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Should I point up the gap in my brickwork?

No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.

Is it messy?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

What’s an expansion joint in brickwork?

It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.

How long should I leave it?

Different products cure at different speeds, so please follow the time we give you when we finish.

What colours does the sealant come in?

The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.

Landlords, agents and businesses in Herne Common

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Housing providers, facilities teams and property managers book us too in Herne Common and across Kent. We can quote a run of properties together, and we’re fully insured for the work.

What we are called out for in Herne Common

Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.

Look out for these signs:

  • Leaking joints around cladding and façade panels
  • Damp patches traced to an open external joint
  • Brick movement joints where the sealant has split
  • Joints pointed up with cement by mistake

If you look after a building such as Herne Church of England Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Choosing a sealant specialist

What happens if it’s left?

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 damage spreads beyond the joint. Around Herne Common, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What external mastic looks like in Herne Common

Herne Common is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.

For landlords with property near Herne Bay station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of St Martin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Surface by surface

Joints between dissimilar materials

Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.

Brickwork movement joints

Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.

When something else is needed

In fairness, some problems need a different trade:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Adding movement joints to masonry that has none
  • Cracked brickwork or render that needs a builder or plasterer

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
