About our mastic sealing in South Green
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. Most enquiries involve old repairs sealed over failed mastic and mastic failing across several blocks on an estate, on communal kitchens and washrooms, shopfronts below residential blocks and communal entrances and stairwells. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in South Green, that means joint design, primers and backing rod as standard.
For owners with a single building near South Green, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Owners, agents and contractors
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Do you need mastic sealing in South Green?
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Look out for the following:
- Cracked, hardened mastic round windows on a block
- Draught complaints from residents or tenants
- Water getting in round frames after rain
- Damaged joints in communal entrances and corridors
Churches, halls and community buildings such as St Mary Magdalene Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Frames, entrances and external joints in South Green
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. At about 35 miles from central London, South Green is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Property owners at sites such as Newington Industrial Estate, 2.9 miles north of South Green, can have mastic renewed between lettings. With historic buildings such as Leeds Castle (to the south of South Green) in the wider area, owners of older properties around South Green should expect mastic to need a product that suits old masonry.

Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Make mastic part of routine maintenance checks
- Log resealing dates block by block
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking a day or two for a single block, longer for an estate programme. For work around South Green, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- 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.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Tell staff and tenants when we will be in
- Explain the parking and delivery arrangements
- Move anything stored against the joints

Advice
Your questions answered
Is a smaller place like South Green outside your area?
No. Places such as South Green are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is Newington Industrial Estate, near South Green, within your area?
Yes, sites like Newington Industrial Estate are within our area, along with the rest of South Green. Photos and a short description are enough for a first look.
Do you do block-wide mastic programmes?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Why act early in South Green
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work with less control over timing. Around South Green, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
