About our mastic sealing in Key's Green
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms, and the failures we’re asked to look at most are open joints in brickwork or panels and worn sealant at communal door frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Key's Green, preparation and product choice get the time they need.
In and around smaller places like Key's Green, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

After the work
For the best life from the joints:
- Share your contractor requirements early
- Plan resealing building by building rather than complaint by complaint
- Have the asbestos survey to hand for older buildings
- Reduce knocks to communal area joints
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
Cost factors for mastic joints
To price the job, we consider:
- The site’s rules and procedures
- How much existing material needs removing
- The size and state of each joint
- Access and working height
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Send us:
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
- Specification clauses that apply
- Anything awkward about access or site hours
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or send details through our quote form if you’d rather talk the job through.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What the job involves on each surface
Planned maintenance
We can work into your cyclical maintenance plan on a timetable you set.
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
FAQs: Key's Green
We manage a building near Frant station. Can you help?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Will you price a mastic programme across our Key's Green portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Do you work in Key's Green?
Yes. We cover Key's Green, and the simplest way to start is to phone 01277 525 020 or email a schedule or drawings.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

Block-wide mastic in Key's Green
At about 32 miles from central London, Key's Green is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Key's Green sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Frant station, 3.5 miles to the south-west of Key's Green, frame and balcony mastic can be renewed on one programme. Older buildings near Key's Green, from historic houses such as Scotney Castle (3.6 miles south-east of Key's Green) to more modest stock, need compatible products when frames are resealed. If you’re responsible for a building such as Chapel Of Ease Of St Luke, frame and door mastic needs the same attention as any other property.

Leave it or put it right?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Around Key's Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
