From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Postling, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Getting the site ready
- Share your working hours and any access restrictions
- Flag any permit to work we’ll need
- Send asbestos survey details if the building is pre-2000

Advice
Facade sealing in Postling, done properly
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have failed sealant on precast panel joints and damp patches beside frames after rain, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Postling is the same: the right product in a properly prepared joint.
Sites around smaller places like Postling can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
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 spell out the cover before we begin.

Your questions answered
Can being near the sea in Postling 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.
Is hospital work, at somewhere like Royal Victoria Hospital, something you do?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Should we check old sealant for asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
Do you work in Postling?
Yes. Postling falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email the details over.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months on every job.
Can the building stay open while you work?
Normally, yes. We phase the work so most of the building stays in use.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Other services in Postling
Mastic packages on Postling sites
The sea is no more than about 3 miles from Postling. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Postling sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
With historic properties like Westenhanger Castle, 1.8 miles to the south-west of Postling, in the area, refurbishment work often meets old masonry that needs compatible sealants. Extensions at sites like Royal Victoria Hospital (4.9 miles east of Postling) usually sit beside working departments, and the mastic follows strict access rules.
Postling is about 3 miles north of Hythe, in Kent. Postling sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 931 places in Kent. Brighton is covered too, some 55 miles away.

Common problems we fix in Postling
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back.
Common reasons buildings call us in:
- Gaps between rainscreen or cladding panels
- Cold air coming in at window perimeters
- Perimeter joints where frames meet the structure
- Sealant pulling away from frames or panels
School extensions, at buildings such as Brockhill Park Performing Arts College, typically run to the summer holidays, mastic included.

Why deal with it now?
Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Older rural buildings around Postling move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access often affects the price as much as the sealing: 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.

When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Damaged frames that need replacing
- Providing access systems for the work
- Water getting in through cracked render or porous masonry
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly.
