External mastic in Chingford Hatch, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. We work on render & cladding joints, joints between brick and frames and copings & trims, and the jobs we see most are cracked joints where brick meets render or frames and old sealant gone brittle and cracked.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Chingford Hatch, tell us how high the joints are and how to reach the back of the building.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Your questions about external mastic in Chingford Hatch
Do you work for landlords with property near Highams Park station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is parking a problem for a job in Chingford Hatch?
Parking in Chingford Hatch, 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.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We’ll tell you when we quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

Landlord and commercial work in Chingford Hatch
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
When something else is needed
To be straight with you, some problems need a different trade:
- Cracked brickwork or render that needs a builder or plasterer
- Damp that isn’t coming from the joint
- Subsidence or other structural problems
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
What we seal
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Copings & trims
- Façade panels
How the job changes by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Act on the first splits you see
- Don’t let climbing plants root in the sealant
- Make sure movement joints aren’t pointed over
- Show decorators and builders where the movement joints are
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
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.
Outside joints around Chingford Hatch
Historic houses like Bruce Castle (about 3.7 miles west) are a reminder that the area around Chingford Hatch has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Highams Park station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near All Saints Church of England Highams Park, the joints between older walls, newer extensions and the roofline need a sealant that can move. Chingford Hatch is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
