External mastic in Homerton
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We work on façade panels, concrete & block and copings & trims, and people most often call us about failed sealant between panels on a façade and gaps where render, brick and frames meet.
Outside work in London starts with access: side passages, upper floors and where to park. In Homerton, joints up high may need ladders or other access, which is worth talking through when you book.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Common problems we fix in Homerton
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Common reasons people contact us include:
- Weathered mastic that no longer stretches
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
As a London address, Homerton can be tricky for parking: let us know about parking bays, permits or a driveway.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Looking after it afterwards
So the new joints stay in good condition:
- Keep movement joints as flexible joints, not mortar
- Have failed joints looked at early
- Walk round the building once a year and look at the joints
- Keep high-pressure jets off the joints
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.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.

Landlords and agents in Homerton can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Homerton buildings and the weather
In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Homerton station, split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as United Reformed Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

FAQs for Homerton
Is Homerton in your area for external mastic?
Yes, Homerton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can parking be tricky for a visit in Homerton?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work usually takes anything from a few hours to several days, depending on the building. In Homerton, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.

What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:

- Rising or penetrating damp from elsewhere in the wall
- Cracks in the bricks or render themselves, away from the joints
