How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. For a village or hamlet like Ninfield, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

External mastic in Ninfield
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. If you’re dealing with brick movement joints where the sealant has split and failed sealant between panels on a façade, we can help, on façade panels, joints between brick and frames and brickwork movement joints alike.
In a village or hamlet like Ninfield, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee, large or small.

What else we do in Ninfield
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Copings & trims
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
- Façade panels
- Brickwork movement joints
What affects the quote in Ninfield
The price is agreed before any work begins. It’s based on:
- Whether old sealant or filler has to be cut out
- The size of the job
- Whether the work is at height
- How many rooms, windows or areas are involved
Combining jobs into one visit normally 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.
What we need to know
You do not need to know the technical terms. Just tell us:
- The rough size of the job
- Any access issues, like height or stairs
- The type of property
- Any previous sealing or DIY work

What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Your questions about external mastic in Ninfield
Do you cover smaller places like Ninfield?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Crowhurst station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height, and we will confirm what access is needed.
Common problems we fix in Ninfield
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
It’s worth asking for a quote if you see:
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Failed seals between different materials
- Leaking joints around cladding and façade panels
For landlords with property near Crowhurst station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Comparing quotes
- Is VAT in the price?
- How the joint is cleaned and prepared
- The length of the guarantee
- How long to leave it before use
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Ninfield, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- A choice of colours where the product allows
- Approved under the ARBOMaster scheme
- Domestic, commercial and hotel work
- Any old sealant cut out fully, not covered over

Ninfield buildings and the weather
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.
Managing a site like Ninfield Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near The Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.
