Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Masonry that has broken away beside the joint
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Failed window or door frames, which need a window contractor
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- External wall and movement joints
- Shopfronts below residential blocks
- Balcony and threshold joints
Mastic sealing in Postling
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. The enquiries we see most involve open joints in brickwork or panels and draughts at frames across a block, on external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms. Whether you call it commercial sealant work, mastic application or joint sealing, in Postling it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Owners and agents with buildings around smaller places such as Postling tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Frames, entrances and external joints in Postling
Postling lies within about 3 miles of the sea. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Postling is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
Blocks of flats and mixed-use buildings often cluster around stations such as Sandling station, 1.3 miles to the south of Postling, and their window and balcony mastic tends to age at the same rate across a building. Historic properties like Westenhanger Castle (to the south-west of Postling) show the age of some local stock, where frame mastic must suit soft brick or stone. Churches, halls and community buildings such as Church of St Mary and St Radegund are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Postling is about 3 miles north of Hythe, in Kent. We cover commercial sites throughout Postling, whether it’s a single job or part of a planned programme. We work across 931 places in Kent, large and small. Our Brighton page has more on work in that area.

Common questions from Postling clients
Do you work for managing agents with blocks near Sandling station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Is a smaller place like Postling outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
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.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Share the asbestos register when you send details
- List the paperwork your organisation requires when you send details
- Ask residents or tenants to report leaks and draughts early
- Plan resealing building by building rather than complaint by complaint
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Why it’s worth doing now in Postling
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Older rural buildings around Postling move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. We plan around the site hours and access windows you give us.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
