Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Your questions answered
Is Conyer too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Could you schedule work at a campus like KITE College for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you clear a mastic snag list before handover?
Yes. Damaged, missed or untidy joints are stripped and done again properly to suit the programme.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
What guarantee comes with a mastic package?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Construction mastic in Conyer, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. We work on window and door perimeters, sanitary and kitchen joints and brick and block movement joints, and the failures we are asked to look at most are oversized or tapered gaps around new frames and caulk cracking where joints are moving more than expected. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Conyer, preparation and product choice get the time they need.
Construction in and around smaller places such as Conyer is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the job changes by surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area and damaged joints are redone rather than patched.
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.
Building owners, agents and FMs in Conyer
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Conyer can form part of a wider programme across Kent.
We work for building owners and managing agents on everything from one building to a spread of sites around Conyer. One quote can cover more than one site, which keeps the paperwork simple.
On site: what to expect
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Conyer need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Before we start on site
- Move anything stored against the joints
- For older buildings, check the asbestos register before work
- Warn occupants and staff about the work

Keeping the joints sound
To get the most from the new sealant:
- Share drawings and the specification as soon as possible
- Record the products used in the O&M file
- Allow flexibility for external sealing in damp or cold weather
- Brief the final clean team to avoid blades near sealant
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out and keeps handover on track.
Mastic packages on Conyer sites
Conyer lies within about 1 mile of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Conyer 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.
Sites around Conyer get mastic sealed to the drawings and the programme, nothing improvised.
Conyer is about 4 miles east of Sittingbourne, in Kent. Looking for construction mastic in Conyer? We can help, as we do across Kent. We work across 931 places in Kent, from busy centres to rural villages. For work in that direction, see our London page.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
What we’re called out for in Conyer
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
These are often picked up first by site or facilities staff:
- Different trades sealing to different standards
- Caulk cracking where joints are moving more than expected
- External joints sealed in damp or cold conditions that are now failing
- Bath and shower joints scraped during the final clean
When a college such as KITE College (3 miles west of Conyer) builds or refurbishes, the mastic package typically has to fit around students and staff.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- Their approach to joint depth and backing
- Will RAMS and insurance details be available?
- Whether primer will be used where the manufacturer specifies it
