Construction mastic in South Street, done properly
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal sealing often fills those days. We work on floor and skirting junctions, brick and block movement joints and cladding and panel joints, and what we are called in for most is snag items on joints that need redoing before handover and existing joints on a refurb that need cutting out and resealing. Facilities teams, main contractors and managing agents in South Street tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In the countryside around places like South Street, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or use the quote form and we’ll come back to it.

On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like South Street are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Flag uneven or tapered frame gaps early
- Share drawings and the specification as soon as possible
- Stick to the specified sealant rather than a generic substitute
- Allow flexibility for external sealing in damp or cold weather
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades which is why protection after sealing matters.
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 flag them as soon as we see them.
Construction mastic around South Street: how the place shapes the job
South Street sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. South Street is about 47 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
School extensions, at buildings such as Boughton-under-Blean and Dunkirk Primary School, usually run to the summer holidays, mastic included. For a contractor working at a hospital such as Eastbridge Hospital of St Thomas the Martyr, 5.7 miles to the east of South Street, perimeter and facade sealing is planned around patients and deliveries. For a contractor at a hotel such as Cave Hotel and Golf Resort (1 mile north of South Street), the mastic often has to be finished before a reopening date.
South Street is about 3 miles south-east of Preston, in Kent. We cover commercial sites throughout South Street, whether it’s a single job or part of a planned programme. South Street is one of 931 places we cover in Kent for mastic packages. London is covered too, around 47 miles from South Street.
Business premises anywhere in ME13 are within our area for mastic packages. If your site is on North Lane and South Street or close by, we can quote for mastic packages. Just outside South Street, we also work in Crouch (1 mile north-west), Oversland (1 mile east), Neames Forstal (1 mile south-west), Hickmans Green (1 mile north-east) and Winterbourne (1 mile east). Bigger towns within reach include Ashford (10 miles south), Canterbury (6 miles east), Sittingbourne (10 miles north-west), Whitstable (6 miles north-east), Faversham (3 miles north-west) and Herne Bay (10 miles north-east).
Local landmarks in South Street
Locally, jobs take us to sites close to Mount Ephraim Gardens and The Sondes Arms, among other places. South Street has its own railway station: Selling station. Other landmarks nearby include Eastbridge Hospital of St Thomas the Martyr (5.7 miles east) and Tower keep castle at Chilham (2.8 miles south). Open spaces near South Street include Blean Woods RSPB Reserve.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in South Street can sit alongside others in a wider programme.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
When to bring in a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Your questions answered
Can you take on a job at a hospital such as Eastbridge Hospital of St Thomas the Martyr?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you keep pace with our programme in South Street?
Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
Do your applicators hold CSCS cards?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. We are fully insured for public liability.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you fit around our programme?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team and adjusted as things change.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Glazing units that are cracked or misted
- Oversized gaps that need packing or adjustment by others
- Joints damaged after sign-off by following trades
Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly.
Joints and surfaces we work on
- Brick and block movement joints
- Cladding and panel joints
- Window and door perimeters
- Internal decorators’ caulk
- Floor and skirting junctions
- Sanitary and kitchen joints
Why it’s worth doing now in South Street
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. If the frame is life-expired, we’ll tell you. Around South Street, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
