Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Balls Green can be grouped with others nearby. You will have a fixed quote before work starts.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Have the specification and drawings to hand
- Tell staff and tenants when we will be in
Getting a fixed quote
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or email a schedule or drawings.

How we handle construction mastic in Balls Green
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. The enquiries we see most involve frame perimeters left unsealed or poorly sealed and a long mastic snag list close to completion, across sanitary and kitchen joints, internal decorators’ caulk and brick and block movement joints. A single leaking joint is often how a building in Balls Green first comes to us: we look at the rest while we are there and tell you what we find.
Construction in and around smaller places such as Balls Green is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Your questions answered
Would you work within a site like Crowborough War Memorial Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you fit the mastic around our build programme in Balls Green?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
What does a mastic package typically include?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens.
Can you seal external joints in wet or cold weather?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. External work is sequenced with some flexibility.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Balls Green can sit alongside others in a wider programme.
Mastic packages on Balls Green sites
Rainfall across the South East, Balls Green included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Balls Green lies roughly 29 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
Older buildings in the area around Balls Green, such as Bassetts Manor, 2.2 miles north-west of Balls Green, need care when sealed: the product has to suit soft or historic materials. For a contractor working at a hospital such as Crowborough War Memorial Hospital, which lies south of Balls Green, perimeter and facade sealing is planned around patients and deliveries.
Balls Green is about 4 miles north of Crowborough, in East Sussex. Anywhere in TN7, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Balls Green is one of 308 places we cover in East Sussex for mastic packages. There’s a separate page for Brighton, about 22 miles away.
Anyone looking for construction mastic in TN7 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside Balls Green, we cover Hartfield (1 mile west), Ashurst (2 miles north-east), Groombridge (2 miles east), Teasley Mead (2 miles north) and Stone Cross (2 miles north-east). Bigger towns within reach include Crowborough (4 miles south), Uckfield (10 miles south), Heathfield (11 miles south-east), Wadhurst (9 miles east), Ridgewood (10 miles south) and Ringmer (15 miles south).
Local landmarks in Balls Green

Why it’s worth doing now in Balls Green
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Called in at the end, the same issues surface during handover. One visit to deal with every failing joint makes more sense than several trips to a place like Balls Green, rather than one at a time. Send photographs of each area and we will quote for the lot.
A quote for mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep finished joints away from paint, plaster and scrapers
- Flag uneven or tapered frame gaps early
- Keep scrapers and abrasive pads off new beads
- Put any product change through the designer first
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We raise them during our first walk of the area.
What we are called out for in Balls Green
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
These are often picked up first by site or facilities staff:
- Mastic snags holding up handover
- Sanitary sealant damaged by following trades
- New external sealant already peeling away
- Internal caulk splitting as the building dries out
Projects at schools like St Michael's Primary School work to term dates, so mastic is programmed tightly.

General trades versus a specialist
Paperwork matters too. 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.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
