External mastic in Aveley
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on copings & trims, joints between brick and frames and concrete & block, and people most often call us about failed seals between different materials and sealant that has lost its bond to the brick or render.
Outbuildings, garages and conservatories around homes in places like Aveley add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

What we’re called out for in Aveley
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
Signs it’s time to call us include:
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
If you look after a building such as Ormiston Park Academy, its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- Is the old sealant removed completely?
- Is VAT in the price?
- What happens if the job turns out different
- How the joint is cleaned and prepared
The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building in most cases. A visit to Aveley is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Different surfaces, different methods
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Outside joints around Aveley
Historic houses like Rainham Hall (about 2.9 miles north-west) are a reminder that the area around Aveley 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. 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.
For landlords with property near Purfleet station, split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Church of St Michael, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Local landmarks in Aveley
Around Aveley, our work takes us to homes and buildings near Belhus, The Old Ship pub and Aveley Primary School. For rail, the closest station is Purfleet station, about 1.5 miles south-west of the centre. A little further out are Stone Castle (4.1 miles south) and Erith Museum (3.5 miles south-west).

Why it’s worth doing now in Aveley
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a smaller place like Aveley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- One-year guarantee on every job
- 180+ five-star Google reviews

- You choose the colour before work begins
Aftercare tips
So the new joints stay in good condition:
- Show decorators and builders where the movement joints are
- Clear growth from the base of walls and joints
- Act on the first splits you see
- Leave the joints unpainted unless we’ve said otherwise
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.
Your questions about external mastic in Aveley
Do you cover smaller places like Aveley?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Purfleet station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
