East Village External Mastic
We cover East Village for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
External mastic for homes and businesses in East Village
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. If you have moss and dirt in joints with no sealant left and gaps where render, brick and frames meet, we can help, on render & cladding joints, brickwork movement joints and joints between brick and frames alike.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
We stand behind the work with a 12-month guarantee.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Act on the first splits you see
- Check external joints each spring
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
When to call us in East Village
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for any of the following:
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
Homes close to St Eleutherius include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Common questions in East Village
Do you cover East Village for external mastic?
Yes. Our work covers London and the South East, and East Village is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Is parking a problem for a job in East Village?
Parking in East Village, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels in East Village.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. In a London area like East Village, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Related advice
External mastic in East Village: local notes
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Stratford International station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Chobham Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the job changes by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
