External & façade joints in Angell Town, Greater London
We cover Angell Town for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Failed seals between different materials
External mastic in Angell Town, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Common call-outs are for cracked joints where brick meets render or frames and old sealant gone brittle and cracked, across render & cladding joints, brickwork movement joints and joints between brick and frames.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Angell Town, check the lease for who looks after the outside.
Your job is guaranteed for a year, as with all our work.

Outside joints around Angell Town
With historic houses such as Buckingham Palace (about 2.6 miles north-west) nearby, there’s older building stock in the area around Angell Town as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
As a London address, Angell Town can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Loughborough Junction station, split movement joints are easy to miss on a rental until damp shows inside.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Joints between brick and frames

How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- Access and height
- Working hours on commercial sites
- How many areas need sealing
- Any mould that needs treating
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Do not let climbing plants root in the sealant
- Act on the first splits you see
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. For a job in Angell Town, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Angell Town: your questions answered
Can you do external mastic in Angell Town?
Yes. Our work covers London and the South East, and Angell Town is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can parking be tricky for a visit in Angell Town?
Parking in Angell Town, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Why it’s worth doing now in Angell Town
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Angell Town, the repair is bigger than a sealant job.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Do you need external mastic in Angell Town?
Buildings move more than people expect. 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.
The problems people usually mention when they call include:
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
If you look after a building such as St John's Angell Town Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
