External mastic in Four Elms

We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you are dealing with brick movement joints where the sealant has split and rain getting behind render or cladding at a joint, we can put it right, whatever the surface.

Around Four Elms, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

All our work is covered by our one-year guarantee, wherever you are in Kent.

Four Elms questions

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

Yes, we work for landlords and letting agents. 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 any work starts.

Can you do external mastic in Four Elms?

Yes. We work across London and the South East, and Four Elms is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Do I have to be there?

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

Can you seal joints between render and window frames?

Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.

Why is there a gap in my brick wall?

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

What should I tell you?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.

How long does external mastic take?

Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. We will confirm how long when we quote.

Is it OK to seal over old sealant?

No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

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, so the problem grows beyond the joint itself. Around Four Elms, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

  • Arbo and Everbuild products
  • Fully insured
  • Anti-fungal silicone where joints get wet

What happens on the day

You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the building in most cases. Somewhere like Four Elms needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We look at every joint and agree a colour to suit the wall.
  2. We take out the old sealant until the faces are sound.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

Preparing for the visit

  • Move anything stored near the joints
  • On commercial sites, let us know about site rules
  • Keep pets and children clear of the area while we work

Advice

Different surfaces, different methods

Joints between dissimilar materials

Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.

Render joints

The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Landlords, agents and businesses in Four Elms

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

External mastic in Four Elms: local notes

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Chartwell (about 2 miles north) are a reminder that the area around Four Elms has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

In the older streets around Congregational Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Edenbridge station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Four Elms Primary School, its movement joints, gutters and trims need looking after like any other building’s.

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Keep movement joints as flexible joints, not mortar
  • Clear growth from the base of walls and joints
  • Fix overflowing gutters above sealed joints
  • Have failed joints looked at early

Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.

Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
