Trusted external mastic in Shoreditch

External mastic in Shoreditch, done properly

For buildings in Shoreditch, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have weathered mastic that no longer stretches and joints pointed up with cement by mistake, we can put it right.

Outside work in London starts with access: side passages, upper floors and where to park. In Shoreditch, joints up high may need ladders or other access, which is worth talking through when you book.

Whatever the size of the job, it’s backed by our 12-month guarantee.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Deal with leaking gutters that soak the joints below
  • Check external joints each spring
  • Keep high-pressure jets off the joints
  • Leave the joints unpainted unless we have said otherwise

Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.

FAQs for Shoreditch

Can you do external mastic in Shoreditch?

Yes, Shoreditch is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.

Is parking an issue for external mastic in Shoreditch?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Where do you work from?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.

Is it OK to fill a movement joint with cement?

No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.

Will the new joint stand out?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Walls and rooflines in Shoreditch

London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. 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.

If you let a flat or house near Shoreditch High Street station, split movement joints are easy to miss on a rental until damp shows inside. Shoreditch is in London, so parking needs planning: let us know about parking bays, permits or a driveway. In the older streets around St Leonard's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we do, step by step

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. For a job in Shoreditch, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. We start by checking each joint, agreeing the ones to redo and how we will reach them.
  2. The old mastic and anything lodged in the joint is removed.
  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. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Related advice

Leave it or put it right?

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.

Landlords, agents and businesses in Shoreditch

For anyone letting property in or around Shoreditch, several properties can be quoted together. Just tell us the addresses and what each one needs.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Can I do it myself?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

What the job involves on each surface

Render joints

Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.

Concrete and blockwork

Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.
