Construction mastic in Postling, done properly
Mastic tends to be one of the final packages before handover. We work as a mastic subcontractor to main contractors and developers with projects in Postling. If you are dealing with mastic snags holding up handover and window and door perimeters that won’t pass inspection, we can help, whatever the surface. 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.
Around smaller places like Postling, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Your questions answered
Is Postling too far out for you?
Not at all. Postling is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
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. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
What happens if the weather stops external sealing?
Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems so it’s better to wait.
Do you do internal caulk as well as external mastic?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging.
Do you do fire-rated sealing on new builds?
We install fire-rated sealant where it is the specified product to the tested detail. We will flag if the detail needs a different product.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Construction mastic in Postling: the local picture
The sea is no more than about 3 miles from Postling. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Postling sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
New wings at hospitals like Royal Victoria Hospital (4.9 miles east of Postling) bring long runs of window and panel joints to seal. Historic houses such as Westenhanger Castle (to the south-west of Postling) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

- Any specification or named product

Do you need construction mastic in Postling?
Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
These are often picked up first by site or facilities staff:
- Sanitary sealant damaged by following trades
- Frame gaps too wide for sealant alone
- New external sealant already peeling away
- Cracks opening in caulked internal joints
When a school such as Brockhill Park Performing Arts College is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Their public liability cover
- Who will actually carry out the work
- What site paperwork they can supply
Looking after the joints
For the best life from the joints:
- Record the products used in the O&M file
- Release areas for mastic once other trades have finished in them
- Share drawings and the specification as soon as possible
- Keep scrapers and abrasive pads off new beads
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement, but caulk in a joint that moves more than expected may crack. If that happens, let us know.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.

What the job involves on each surface
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
