Our process
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Several jobs near Murston can be grouped on one trip. Tell us your site hours and we will plan around them.
- Drawings, the sealant specification and your programme come to us for pricing.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Let building users know which areas are affected
- Tell us your opening times and when work is allowed

Construction mastic for commercial buildings in Murston
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Murston, send drawings and the specification through our quote form. If you have early adhesion failures on new external joints and sealant knocked or painted over by other trades, we can put it right, on window and door perimeters, floor and skirting junctions and brick and block movement joints alike. A single leaking joint is often how a building in Murston first comes to us: we look at the rest while we’re there and tell you what we find.
Around places like Murston, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

After the work
Regular inspection catches problems early. In particular:
- Don’t force external sealing on a damp or frosty day
- Check frame gaps are within the sealant’s range before sealing
- Keep product details for future maintenance
- Put any product change through the designer first
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover as agreed in the quote.
One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area, and a delay to handover. Checking perimeters before internal finishes go on avoids it.
Common questions from Murston clients
Can work at a site such as KITE College fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Sittingbourne Memorial Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is the mastic package guaranteed?
It’s backed by our 12-month guarantee, covering how we sealed. Keeping other trades off finished joints prevents most problems.
Do your applicators hold CSCS cards?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
What do you charge?
Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or use the quote form.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
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.
Mastic packages on Murston sites
Murston is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Murston 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 we time external mastic for dry faces and agree it with the site team.
New wings at hospitals like Sittingbourne Memorial Hospital, 0.8 miles to the south-west of Murston, bring long runs of window and panel joints to seal. For contractors at a school such as Sunny Bank Primary School, sealing has to be finished before term starts.
Murston is about 1 mile east of Sittingbourne, in Kent. Commercial clients in Murston use us for work on mastic packages, as part of our coverage of Kent. Murston is one of 931 places we cover in Kent for mastic packages. Sites around London have their own page, about 38 miles away.

Different surfaces, different methods
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team before sealing starts.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control.
When to call us in Murston
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
It’s worth sending us details if you spot any of the following:
- Sealant knocked or painted over by other trades
- A long mastic snag list close to completion
- Failed sealant in an existing building being refurbished
- Oversized or tapered gaps around new frames
Recladding or extending a unit at a site like Kent Science Park (2.3 miles south-west of Murston) brings panel joints and frame perimeters into the programme.

What else we do in Murston
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
