About our mastic sealing in Kingsnorth
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, communal kitchens and washrooms and shopfronts below residential blocks, and what we are called in for most is a mix of products and colours from past repairs and open joints in brickwork or panels. Whoever orders the work in Kingsnorth, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Owners and agents with buildings around smaller places such as Kingsnorth 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Questions we’re asked in Kingsnorth
Will you take on a block within reach of Gillingham (Kent) station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Is Kingsnorth too small for you to travel to?
No. Places such as Kingsnorth are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Do you need mastic sealing in Kingsnorth?
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.
Any of the following is a good reason to get the joints checked over:
- Complaints coming in block by block
- Leaks at window and door perimeters
- Estate-wide sealant that is simply worn out
- Communal area joints that look neglected
Site managers at schools like The Hundred of Hoo Academy can fit frame mastic into the summer works.
What your quote should include
- What level of public liability insurance do they hold?
- Their plan for phasing and protecting the area
- The named product and why it was chosen
- Do they follow the manufacturer’s priming guidance?
Blocks and managed buildings in Kingsnorth
The sea is no more than about 1 mile from Kingsnorth. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Kingsnorth 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 usually need attention first.
If you manage student housing near a university such as University of Greenwich - Medway, 3.4 miles south-west of Kingsnorth, the summer turnaround is the time for mastic. Blocks of flats and mixed-use buildings often cluster around stations such as Gillingham (Kent) station (3.6 miles south-west of Kingsnorth) and their window and balcony mastic tends to age at the same rate across a building.
Kingsnorth is about 4 miles north of Gillingham, in Medway. Kingsnorth sits inside our coverage and the rest of Medway, with the same fixed quotes and 12-month guarantee as everywhere else. Kingsnorth is one of 54 places we cover in Medway. We also cover London, some 30 miles away.
Postcode districts covered here: ME3 for mastic joints. For a building on Jetty Road and Jacob's Lane or nearby, send details and we will quote for mastic joints.

Near you in Kingsnorth
The nearest railway station is Gillingham (Kent) station, roughly 3.6 miles south-west of the centre. Nearby you’ll also find Medway Maritime Hospital (4.2 miles south-west) and Upnor Castle (3.5 miles south-west). The countryside around Kingsnorth includes Bishop Saltings.
Why it’s worth doing now in Kingsnorth
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Converted and older buildings near places like Kingsnorth tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a day or two for a single block, longer for an estate programme. Jobs in and around smaller places like Kingsnorth are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Getting the site ready
- Flag any permit to work we will need
- Let building users know which areas are affected
- Arrange parking or a loading space

Advice
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Kingsnorth can form part of a wider programme.
When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
If in doubt, ring 01277 525 020 or email the details over and we will say what we think.
Surfaces we seal
