About our construction mastic in Sandway
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. The enquiries we see most involve window and door perimeters that won’t pass inspection and different trades sealing to different standards, on cladding and panel joints, window and door perimeters and internal decorators’ caulk. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Sandway is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Sites around smaller places like Sandway can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.
Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or use the quote form and we’ll arrange a return visit.

What we are called out for in Sandway
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
Most enquiries start with something like this:
- Perimeter gaps outside the sealant’s range
- Internal caulk splitting as the building dries out
- Existing joints on a refurb that need cutting out and resealing
- Different trades sealing to different standards
School extensions, at buildings such as Platts Heath Primary School, normally run to the summer holidays, mastic included.
Comparing quotes
- Proof of insurance
- Who will actually carry out the work
- Whether primer will be used where the manufacturer specifies it
- Their approach to joint depth and backing

Sandway: questions and answers
Is Sandway too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Will you take on work at estates like Roebuck Business Park, close to Sandway?
Yes. We cover Sandway and the area around it, including industrial estates, business parks and retail parks such as Roebuck Business Park. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, and each applicator is CSCS-carded. We’re fully insured for public liability.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Do you use the sealant named in the specification?
We follow the specified sealant. Specifications often reference BS EN 15651 or BS 6213.
Leave it or put it right?
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Leave it late and they turn up on the snag list. Older rural buildings around Sandway move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Construction mastic in Sandway: the local picture
Sandway is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Sandway lies roughly 39 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
For a contractor at a hotel such as Chilston Park Hotel, 0.8 miles south-east of Sandway, the mastic often has to be finished before a reopening date. Historic houses such as Leeds Castle (3.3 miles north-west of Sandway) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Sandway is about 8 miles east of Maidstone, in Kent. Our applicators travel to Sandway for work on mastic packages, handled exactly as we handle every other area. We work across 931 places in Kent. London is covered too, around 39 miles from Sandway.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Don’t force external sealing on a damp or frosty day
- Don’t schedule sealing before decorators and flooring are done
- Keep scrapers and abrasive pads off new beads
- Ask installers to correct oversized gaps first
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work.
What the job involves on each surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
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.
