Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Group repairs into a planned programme
- Look at the sunniest and most exposed elevations first
- Keep bins and bikes away from communal door frames
- Track which buildings were done and when
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
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.
About our mastic sealing in Flowers Green
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints, and the usual reasons a site gets in touch are no planned programme for sealant and occupiers reporting cold air round windows. A single leaking joint is often how a building in Flowers Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Rural conversions near places like Flowers Green often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think before you book.

Our process
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Flowers Green, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Let building users know which areas are affected
- Point out any areas we must not close
- Make sure the joints can be reached

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Signs you need mastic sealing in Flowers Green
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
Typical triggers for a call:
- Communal area joints that look neglected
- Repeated reactive repairs to the same buildings
- Failed external movement joints
- Draughts at frames across a block
Schools and community buildings such as Herstmonceux Church of England Primary School need frame and external mastic kept sound like any building.

Why act early in Flowers Green
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish and one 12-month guarantee. Older rural buildings around Flowers Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Mastic sealing in Flowers Green: the local picture
Flowers Green lies roughly 46 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
Historic properties like Horselunges Manor (3.4 miles west of Flowers Green) show the age of some local stock, where frame mastic must suit soft brick or stone. Blocks of flats and mixed-use buildings often cluster around stations such as Pevensey Bay station (4.4 miles south of Flowers Green) and their window and balcony mastic tends to age at the same rate across a building.
