What we can’t put right
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Façade panels
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
About our external mastic in Pleshey
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. We work on concrete & block, joints between brick and frames and façade panels, and people most often call us about old sealant gone brittle and cracked and failed sealant between panels on a façade.
In a village or hamlet like Pleshey, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
You get a 12-month guarantee, the same in Pleshey as everywhere else we work.

How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Pleshey needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Advice
Signs you need external mastic in Pleshey
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Keep an eye out for these signs:
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
Around Pleshey, as everywhere, external mastic is only as good as the preparation behind it.
Questions to ask before booking
- Are they insured?
- Whether they seal over old material or remove it
- Whether you can choose the colour
- What product goes in the joint
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Leave the joints unpainted unless we have said otherwise
- Act on the first splits you see
- Look over the joints every year, ideally after winter
- Deal with leaking gutters that soak the joints below
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. Catch it early and you reduce the risk.
What external mastic looks like in Pleshey
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of Holy Trinity, an extension built onto an older house moves differently, and the joint between them takes the strain.

Pleshey: your questions answered
Will you come out to Pleshey?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee on external mastic in Pleshey?
All our work, in Pleshey and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Why it’s worth doing now in Pleshey
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Pleshey, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we’ll talk you through it.
