External mastic for homes and businesses in Thames View Estate
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We work on render & cladding joints, brickwork movement joints and joints between brick and frames, and the jobs we see most are leaking joints around cladding and façade panels and water getting into walls through failed joints.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Thames View Estate, tell us how high the joints are and how to reach the back of the building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
- Act on the first splits you see
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.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- The size of the job
- Which sealant suits the joint
- How many areas need sealing
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
To make quoting easier, let us know:
- Whether it’s a home or a business
- What’s wrong with the joints now
- If someone has resealed it before
- Roughly how big the job is
We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or email us and describe the job.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the building. For a job in Thames View Estate, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Advice
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In a flat in Thames View Estate, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Towns and villages near Thames View Estate
What else we do in Thames View Estate
Do you need external mastic in Thames View Estate?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Common reasons people contact us include:
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
For site and facilities teams at buildings such as Thames View Infants, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Whether the sealant suits the joint
- What insurance they hold
- Whether VAT is included
- Is the old sealant removed completely?

What external mastic looks like in Thames View Estate
With historic houses such as Eastbury Manor House (about 0.5 miles north-west) nearby, there’s older building stock in the area around Thames View Estate as well as newer homes. In older buildings, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Barking Riverside station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Christ Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
