About our construction mastic in South Green
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list. Our aim is joints that pass at the first inspection, whatever the size of the scheme. We work on window and door perimeters, brick and block movement joints and cladding and panel joints, and the usual reasons a site gets in touch are existing joints on a refurb that need cutting out and resealing and a long mastic snag list close to completion. For commercial sealant work in South Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For a site near South Green, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What the job involves on each surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Frames fitted out of tolerance
- Designing joint widths or choosing the specification (that sits with the designer)
- Faulty frames rather than failed sealant
If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.

Why act early in South Green
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple and a consistent finish. Older rural buildings around South Green move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

New build and refits around South Green
South Green lies roughly 35 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, South 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, which is why external dates are agreed with the site manager.
For a contractor working at a hospital such as KIMS hospital, 4.5 miles west of South Green, perimeter and facade sealing is planned around patients and deliveries. Older buildings in the area around South Green, such as Leeds Castle, 4.4 miles to the south of South Green, need care when sealed: the product has to suit soft or historic materials.
South Green is about 4 miles south-west of Sittingbourne, in Kent. Our applicators travel to South Green for work on mastic packages. Our Kent coverage takes in 931 places. For work in that direction, see our London page.

FAQs: South Green
Can you take on a job at a hospital such as KIMS hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work around term dates at a campus such as Canterbury Christ Church University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use.
What accreditations do you hold?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Common problems we fix in South Green
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Choosing the right product for each joint reduces that.
Things that typically lead to an enquiry:
- Different trades sealing to different standards
- Failed sealant in an existing building being refurbished
- Caulk cracking where joints are moving more than expected
- Snag items on joints that need redoing before handover
Units on estates such as Newington Industrial Estate, 2.9 miles to the north of South Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
