Coloured sealant for Dungate sites

How we handle coloured sealant in Dungate

We take on colour-matched work across new fit-outs, refurbishments and resealing of existing joints. On resealing, matching the existing colour is often as important as the seal itself, especially on a listed or high-profile elevation. We work on office fit-out finishes, shop-fit joinery and counters and cladding panels, and the usual reasons a site gets in touch are weathered sealant that no longer matches and failed coloured sealant that has split or peeled. A single leaking joint is often how a building in Dungate first comes to us: we look at the rest while we are there and tell you what we find.

Commercial sealant work around smaller places like Dungate tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Surface by surface

Shop-fit and joinery finishes

Retail fit-outs mix many finishes in a small space. Each joint gets a colour that suits the materials it sits between from the product’s range.

Cladding panels

Panel joints form a grid on the facade, so colour matters. We pick a facade-grade sealant in a shade that sits with the panels, rated for the joint’s movement.

What Dungate’s businesses ask us to seal

At about 39 miles from central London, Dungate is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. Dungate sits in one of the drier corners of the country, the South East. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

Offices at parks like Kent Science Park (1.3 miles north-west of Dungate) have receptions, kitchens and glazed partitions where a tidy joint matters.

Dungate is about 3 miles south of Sittingbourne, in Kent. Any commercial site in Dungate is covered. Dungate is one of 931 places we cover in Kent. Our London page has more on work in that area, about 39 miles away.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If others near Dungate need work, visits can be combined. You will have a fixed quote before work starts.

  1. We confirm the joint type and the product it needs.
  2. We compare the target colour with the colours available.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

  • Flag any permit to work we will need
  • Agree which areas must stay open
  • Have the specification and drawings to hand

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Quoting for work in Dungate

Your fixed quote is built from the real scope. It allows for:

  • Travel to remote or island sites
  • Whether the work must be split into stages
  • How accessible the joints are
  • Backing rod, priming and other preparation

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • The product your specification calls for
  • Whether the building will be occupied during the work
  • Your programme or deadline
  • Where the site is, with the postcode

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Dungate: questions and answers

Can the sealant on our Dungate premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photographs and we’ll confirm what’s available for the product.

Is Kent Science Park, near Dungate, within your area?

Yes, sites like Kent Science Park are within our area, along with the rest of Dungate. Photos and a short description are enough for a first look.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Do you work in Dungate?

Yes. We cover Dungate, and you can ring 01277 525 020 or email us to get started.

Common problems we fix in Dungate

Failed sealant still has to be dealt with, whatever its colour: splits, adhesion loss and hardening all happen. The fix is a full cut-out and a new bead in the right colour.

What tends to prompt an enquiry:

  • Smeared sealant on stone or joinery
  • Dirty, discoloured joints in public areas
  • Hotel refurbishments with a set colour scheme
  • Weathered sealant that no longer matches

Offices and shops close to stations such as Sittingbourne station, 2.9 miles to the north of Dungate, tend to be busy all day, so sealant work is planned around opening hours.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the joint faces will be prepared and primed
  • Their public liability cover
  • Are they CHAS accredited or on Constructionline?

Why act early in Dungate

A mismatched or discoloured bead is a small detail that buyers, guests and clients notice. Putting it right costs little compared with the finishes around it, and the difference is obvious. Around Dungate, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
