Spitalfields External Mastic
Our applicators work in Spitalfields on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Joints with sealant missing in places
Honest limits
It helps to know what we cannot do:
- Loose or hollow render, which needs re-rendering
- Damp that is not coming from the joint
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
What we seal
- Copings & trims
- Façade panels
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
- Brickwork movement joints
External mastic in Spitalfields
For buildings in Spitalfields, 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’re dealing with joints with sealant missing in places and damp patches traced to an open external joint, we can put it right, whatever the surface.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
To keep the joints looking good and working properly:
- Leave the joints unpainted unless we have said otherwise
- Clear growth from the base of walls and joints
- Avoid pressure-washing directly into sealant joints
- Tell anyone working on the walls about the movement joints
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
External mastic in Spitalfields: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
Letting a property close to London Liverpool Street station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Christ Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. As a London address, Spitalfields can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Leave it or put it right?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, rather than the wall around it. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Spitalfields, the repair is bigger than a sealant job.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. For a job in Spitalfields, 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.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Advice
Different surfaces, different methods
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
