External mastic in London Fields, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. We’re often asked to deal with sealant pulling away from one side of the joint and weathered mastic that no longer stretches, on copings & trims, render & cladding joints and joints between brick and frames.
Outside work in London starts with access: side passages, upper floors and where to park. In London Fields, joints up high may need ladders or other access, which is worth talking through when you book.
Your job is guaranteed for a year, as with all our work.

What we are called out for in London Fields
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Weeds or debris growing in open joints
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
As a London address, London Fields can be tricky for parking: let us know about parking bays, permits or a driveway.
Before you book anyone
- Whether all the old sealant comes out first
- What product goes in the joint
- Who turns up on the day
- What guarantee comes with the work
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

Common questions in London Fields
Can you do external mastic in London Fields?
Yes. We work across London and the South East, and London Fields is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near London Fields station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Are you insured?
Yes. We’re fully insured.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before any work starts, matched as closely as the range allows.
How long will you be here?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Why act early in London Fields
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a flat in London Fields, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. In a London area like London Fields, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Tell us about any water getting in
- Let us know about parking restrictions
- Move anything stored near the joints
Getting a quote

How to look after the new joints
Looking after new joints is easy:
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Outside joints around London Fields
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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Michael and All Angels, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Gayhurst Community School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
