How we handle mastic sealing in Heaverham
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 if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you have draught complaints from residents or tenants and damp patches beside frames, we can put it right, on external wall and movement joints, balcony and threshold joints and shopfronts below residential blocks alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Heaverham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Heaverham, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Every job we finish is backed by a 12-month workmanship guarantee, in Heaverham as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
- Masonry that has broken away beside the joint
If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.
Surfaces we seal
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Communal kitchens and washrooms
Common problems we fix in Heaverham
The edges of the material itself sometimes break away for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
These are often picked up first by site or facilities staff:
- Mastic failing across several blocks on an estate
- Damaged joints in communal entrances and corridors
- Movement joints with sealant missing
- Repeated reactive repairs to the same buildings
Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

How the job changes by surface
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
Owners, agents and contractors
CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Common questions from Heaverham clients
Does your area include sites such as Chaucer Business Park, near Heaverham?
Yes. Our area takes in Heaverham and its surroundings, with estates and business parks such as Chaucer Business Park included. A few photos and the unit address let us price the work.
We manage a building near Kemsing station. Can you help?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
For owners and agents in Heaverham
Rainfall across the South East, Heaverham 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. At about 20 miles from central London, Heaverham is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Buildings close to stations like Kemsing station, 0.6 miles south-west of Heaverham, are often flats over shops, with frame mastic to keep sound. If you own or manage units on a site such as Chaucer Business Park, which lies south-west of Heaverham, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

What’s near Heaverham
We work on buildings around Wrotham School, The Chequers Public House and Kemsing Down. The closest station to Heaverham is Kemsing station, roughly 0.6 miles south-west. Other landmarks nearby include Otford Heritage Centre (2.5 miles west) and Kemsing Castle Bank (1 mile west). Not far away are Dryhill Nature Reserve.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Encourage occupiers to report problems at frames
- Mention RAMS, insurance or CSCS requirements up front
- Avoid piecemeal callouts where you can
- Make mastic part of routine maintenance checks
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
