Mastic sealing near South Stour
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Aftercare for building managers
To get the most from the new sealant:
- Share the asbestos register when you send details
- Avoid piecemeal callouts where you can
- Make it easy for occupiers to report draughts
- Log resealing dates block by block
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
How we handle mastic sealing in South Stour
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on external wall and movement joints, window and door perimeters on blocks and communal entrances and stairwells, and what we are called in for most is communal area joints that look neglected and leaks at window and door perimeters. A single leaking joint is often how a building in South Stour first comes to us: we look at the rest while we’re there and tell you what we find.
Rural conversions near places like South Stour often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
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’re clear about what is covered before work starts.

Looking after buildings in and around South Stour
South Stour is about 51 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, South Stour included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Historic properties like Godinton House, 4.8 miles to the north-west of South Stour, show the age of some local stock, where frame mastic must suit soft brick or stone. If you look after a block within reach of Ashford International station (2.8 miles north-west of South Stour), frame and balcony mastic can be renewed on one programme.
South Stour is about 3 miles south-east of Ashford, in Kent. We send applicators to South Stour for mastic joints. South Stour is one of 931 places we cover in Kent for mastic joints. We also cover Brighton, around 49 miles from South Stour.

Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near South Stour may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- 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.
Before we start on site
- Point out any areas we must not close
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Substrate edges that need repairing first
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Surfaces we seal
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Window and door perimeters on blocks
When to call us in South Stour
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
If one of these sounds familiar, it’s time for a closer look:
- The same joint failures repeated across a portfolio
- Water getting in round frames after rain
- Window mastic that has split and shrunk
- Complaints coming in block by block
Site managers at schools like Finberry Primary School can fit frame mastic into the summer works.
What to look for in a quote
- How the joint faces will be prepared and primed
- Will CSCS-carded applicators be on site?
- What site paperwork they can supply
- Is the sealant right for the movement and the substrate?
Other services in South Stour
General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Questions about South Stour
Is South Stour off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you work at a site such as Bliby Business Centre, by South Stour?
Yes. Our area takes in South Stour and its surroundings, with estates and business parks such as Bliby Business Centre included. Send details of the unit and the work through our quote form for a quick quote.
Do you do block-wide mastic programmes?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How long will the new sealant 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.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What happens if it’s left?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. One visit to deal with every failing joint makes more sense than several trips to a place like South Stour, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
