How the job changes by surface
Communal areas
We keep entrances and stairs open throughout. Work is planned in sections.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Mastic sealing for commercial buildings in Flimwell
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you have patchy repairs in mismatched sealant and draughts at frames across a block, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Flimwell is the same: the right product in a properly prepared joint.
In and around smaller places like Flimwell, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Planned mastic for Flimwell portfolios
Flimwell lies roughly 39 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Older buildings near Flimwell, from historic houses such as Scotney Castle, 3.1 miles north-west of Flimwell, to more modest stock, need compatible products when frames are resealed. Landlords with units on estates such as Parsonage Farm Business Centre (2 miles south-west of Flimwell) can bring frame, door and external mastic across several units into one programme. Churches, halls and community buildings such as St Augustine's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Flimwell is about 10 miles south-east of Royal Tunbridge Wells, in East Sussex. We cover commercial sites throughout Flimwell. Flimwell is one of 308 places we cover in East Sussex. Brighton is covered too, some 29 miles away.
Work on mastic joints is covered throughout TN5, whatever the building. Buildings on High Street, London Road and Corner Farm Close are within our area. You will find Flimwell on or near the B2087, so getting applicators and materials to site is simple. If your building is just outside Flimwell, we cover Stonecrouch (2 miles north-west), Ticehurst (2 miles west), Three Leg Cross (2 miles west), Cooper's Corner (2 miles south-east) and Bedgebury Cross (2 miles north). Bigger towns within reach include Hastings (14 miles south), Bexhill-on-Sea (14 miles south), Hailsham (15 miles south-west), Crowborough (12 miles west), St Leonards (14 miles south) and Hastings Old Town (15 miles south-east).

The nearest railway station is Etchingham station, roughly 3 miles south. A little further out are Ticehurst House Hospital (2 miles west) and Finchcocks Musical Museum (3.5 miles north). For a walk, there’s Bewl Water.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
After the work
For the best life from the joints:
- Check the asbestos register before any old mastic is disturbed
- Ask residents or tenants to report leaks and draughts early
- Start inspections with the most exposed faces
- List the paperwork your organisation requires when you send details
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Flimwell need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Share the asbestos register for older buildings
- Have the specification and drawings to hand

Questions about Flimwell
Do you cover business parks and estates near Flimwell, such as Parsonage Farm Business Centre?
Yes. Estates, retail parks and business parks around Flimwell, Parsonage Farm Business Centre among them, are all within reach. A few photos and the unit address let us price the work.
Will you take on a block within reach of Etchingham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Leaks through the frame itself rather than the perimeter
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
