How we handle construction mastic in Hartlip
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, with public liability insurance in place. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. If you’re dealing with different trades sealing to different standards and sealant knocked or painted over by other trades, we can help. A single leaking joint is often how a building in Hartlip first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions of older rural buildings near smaller places such as Hartlip bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What else we do in Hartlip
Why it’s worth doing now in Hartlip
Sealing over damaged or contaminated new joints might save a day. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Hartlip. Send photos of each area and we will quote for the lot.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Why appoint us
- Failed material removed, not covered up
- Sealing commercial buildings since 2005
- Our applicators hold CSCS cards
- Colour agreed before work starts

What affects the price in Hartlip
We price every job individually. The main factors are:
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
- Location, for remote and island sites
- Access and working height
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
- Any dates the work must fit around
- How the joints are reached, and at what height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
Our process
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a building around Hartlip, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site

- Send your site hours and access windows
- Send any specification or drawings in advance
Ask for a quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Questions we’re asked in Hartlip
Will you take on work at estates like Newington Industrial Estate, close to Hartlip?
Yes, sites like Newington Industrial Estate are within our area, along with the rest of Hartlip. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is a hospital such as Medway Maritime Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can you clear a mastic snag list before handover?
Yes. Send the snag list or photos and we’ll price it.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Contractors’ notes for Hartlip
Hartlip is within about 3 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Hartlip sits in one of the drier corners of the country, the South East. 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.
Hospital estates such as Medway Maritime Hospital (4.8 miles north-west of Hartlip) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. When units on a site such as Newington Industrial Estate, 0.7 miles to the north-east of Hartlip, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Hartlip is about 3 miles south-east of Gillingham, in Kent. Our applicators travel to Hartlip for work on mastic packages. Across Kent, 931 places are covered, Hartlip among them. There’s a separate page for London, about 33 miles away.

Signs you need construction mastic in Hartlip
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Common reasons buildings call us in:
- Sanitary sealant damaged by following trades
- Different trades sealing to different standards
- Perimeter gaps outside the sealant’s range
- Early adhesion failures on new external joints
School extensions, at buildings such as Hartlip Endowed Church of England Primary School, usually run to the summer holidays, mastic included.
