Mastic sealing in Highstreet
For blocks and buildings in Highstreet and across Kent, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. Most enquiries involve draughts at frames across a block and water getting in round frames after rain, across window and door perimeters on blocks, communal kitchens and washrooms and shopfronts below residential blocks. Whoever orders the work in Highstreet, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Different surfaces, different methods
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler and easier to manage.
On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a building around Highstreet, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Share the asbestos register for older buildings
- Warn occupants and staff about the work

Advice
Common questions from Highstreet clients
Can being near the sea in Highstreet affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Does your area include sites such as Waterham Business Park, near Highstreet?
Yes. Estates, retail parks and business parks around Highstreet, Waterham Business Park among them, are all within reach. A few photos and the unit address let us price the work.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Do you cover Highstreet?
Yes. We take on work across Highstreet.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you reseal a whole block or estate?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
When to call us in Highstreet
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
If one of these sounds familiar, it’s time for a closer look:
- Damp patches beside frames
- Failed external movement joints
- Patchy repairs in mismatched sealant
- Draughts at frames across a block
If you look after a block within reach of Whitstable station, 3 miles to the north-east of Highstreet, frame and balcony mastic can be renewed on one programme.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- Will failed sealant be removed rather than covered?
- Their approach to joint depth and backing
- Who will actually carry out the work
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Check the asbestos register before any old mastic is disturbed
- Include mastic in your cyclical inspections
- Encourage occupiers to report problems at frames
- Group repairs into a planned programme
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Mastic sealing around Highstreet: what changes locally
Highstreet sits close to the coast, within about 2 miles. On buildings near the shore, the side facing the weather normally needs its mastic renewed first; plan inspections around that. Highstreet is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Student accommodation around universities such as University of Kent, 3.9 miles south-east of Highstreet, is normally managed block by block, which suits a planned mastic programme. Landlords with units on estates such as Waterham Business Park, less than half a mile to the west of Highstreet, can bring frame, door and external mastic across several units into one programme.
