External & façade joints in Temple Mills, Greater London
Professional external mastic in and around Temple Mills, with old sealant always removed completely and a 12-month guarantee.
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
How we handle external mastic in Temple Mills
For buildings in Temple Mills, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Typical jobs include cracked joints where brick meets render or frames and failed sealant between panels on a façade, across render & cladding joints, façade panels and brickwork movement joints.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall, and both kinds of building are found across London.
All our work comes with a 12-month guarantee.

Common problems we fix in Temple Mills
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and make things worse.
These are the problems we’re asked about most:
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
As a London address, Temple Mills can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Before booking anyone
- The length of the guarantee
- Who turns up on the day
- How the joint is cleaned and prepared
- Whether VAT is included
How to look after the new joints
To keep the joints looking good and working properly:
- Make sure movement joints are not pointed over
- Wash walls gently around the sealant
- Check external joints each spring
- Fix overflowing gutters above sealed joints
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Honest limits
A few problems are outside what sealant work can do:
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint

What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so neither cracks the other.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Why act early in Temple Mills
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Temple Mills, the repair is bigger than a sealant job.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Old sealant always removed completely
- Homes, businesses and hotels
- Anti-fungal silicone where joints get wet
- A sealant colour to suit the surroundings
Temple Mills buildings and the weather
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. 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.
Homes close to St Eleutherius include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Stratford International station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Common questions in Temple Mills
Do you cover Temple Mills for external mastic?
Yes, Temple Mills is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is parking an issue for external mastic in Temple Mills?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
What is backing rod for?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation. In Temple Mills, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
