Construction mastic for businesses in Dungate
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Ask cleaners to use soft cloths around fresh sealant
- Don’t force external sealing on a damp or frosty day
- Share drawings and the specification as soon as possible
- Record the products used in the O&M file
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.
Construction mastic in Dungate
Getting a subcontractor through site induction should be simple. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. If you’re dealing with mastic snags holding up handover and internal caulk splitting as the building dries out, we can help, on floor and skirting junctions, brick and block movement joints and internal decorators’ caulk alike. Most enquiries from Dungate start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Construction in and around smaller places such as Dungate 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Site staff or a sealant 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.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Signs you need construction mastic in Dungate
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Site and facilities staff are often the first to spot these:
- Inconsistent sealant finishes from plot to plot
- Oversized or tapered gaps around new frames
- Failed sealant in an existing building being refurbished
- Caulk cracking where joints are moving more than expected
Projects at schools like Milstead and Frinsted Church of England Primary School work to term dates, so mastic is programmed tightly.
What your quote should include
- Can the work be phased to keep areas open?
- Which product they’ll use, and why it suits the joint
- Will CSCS-carded applicators be on site?
- How they handle RAMS and site documents
Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Dungate, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Before we start on site
- Make sure the joints can be reached
- Confirm the product named in the specification
- Agree which areas must stay open

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Contractors’ notes for Dungate
Dungate is about 39 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Dungate 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, so the external programme keeps a little slack.
For contractors on a campus like Canterbury Christ Church University (3.8 miles south-west of Dungate), facade and perimeter sealing has to fit around students and term dates. Projects at colleges like Sittingbourne College (to the north-west of Dungate) tend to run to term dates, so the mastic is planned tightly.
Dungate is about 3 miles south of Sittingbourne, in Kent. Anywhere in ME9, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Kent, 931 places are covered, Dungate among them. Our London page has more on work in that area, about 39 miles away.
