Mastic sealing for South Street sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
Before we quote, we look at:
- Travel to remote or island sites
- Induction, permit and paperwork requirements
- The product specified
- Removal of failed or old sealant
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- The asbestos register, for older buildings
- The product your specification calls for
- How the joints are reached, and at what height
- Any dates the work must fit around
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.
How we handle mastic sealing in South Street
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are draughts at frames across a block and open joints in brickwork or panels. For commercial sealant work in South Street, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Owners and agents with buildings around smaller places such as South Street tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Looking after buildings in and around South Street
Central London is about 22 miles from South Street. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. South Street sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
Schools and community buildings such as Culverstone Green Primary School need frame and external mastic kept sound like any building. Buildings close to stations like Meopham station, 2.4 miles north of South Street, are often flats over shops, with frame mastic to keep sound.
South Street is about 6 miles south of Gravesend, in Kent. Commercial clients in South Street can call on us for mastic joints, as part of our coverage of Kent. Our Kent coverage takes in 931 places, from busy centres to rural villages. London is covered too, some 22 miles away.
If you need mastic sealing in DA13, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on South Street and Chapman's Hill are within our area for mastic joints. Nearby places we also cover include New Street (1 mile west), Priestwood Green (1 mile east), Culverstone Green (1 mile south), Harvel (1 mile south-east) and Priestwood (1 mile east) for mastic joints. Further afield, our area takes in Maidstone (10 miles south-east), Dartford (8 miles north-west), Sevenoaks (9 miles south-west), Royal Tunbridge Wells (15 miles south), Gravesend (6 miles north) and Tonbridge (11 miles south).
What’s near South Street
In South Street, that means premises near Trosley Country Park and Meopham School, among other places. The nearest railway station is Meopham station, about 2.4 miles north. Well-known places in the area include Leybourne Castle (4.5 miles south-east) and Coldrum Long Barrow (2.3 miles south-east).
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Glazing that needs replacing
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Failed window or door frames, which need a window contractor
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Joints and surfaces we work on
- Balcony and threshold joints
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
South Street: questions and answers
Is South Street too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you quote for a block close to Meopham station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
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 inspection is the best way to catch problems early.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

What else we do in South Street
Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. Around South Street, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
Pricing mastic joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

- Over 20 years of commercial sealing
- Constructionline member
- Old sealant cut out, never sealed over
- Clear, fixed quotes
Do you need mastic sealing in South Street?
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
It’s worth sending us details if you spot any of the following:
- Open joints in brickwork or panels
- Cracked, hardened mastic round windows on a block
- Damaged joints in communal entrances and corridors
- The same joint failures repeated across a portfolio
With historic buildings such as Cobham College, 3.3 miles north-east of South Street, in the wider area, owners of older properties around South Street should expect mastic to need a product that suits old masonry.
