How we handle coloured sealant in Sittingbourne

Matching to anodised or powder-coated frames is a common request. We compare the RAL reference with the colours made for the specified sealant. If the range has no close colour, a paintable sealant can sometimes be overpainted, where the specification allows. We work on cladding panels, natural stone and brick and office fit-out finishes, and what we’re called in for most is smeared sealant on stone or joinery and discoloured joints on a visible elevation. One point of contact handles commercial sealant work in Sittingbourne from the first photographs to the final walk-round, for single jobs and planned programmes alike.

In towns of Sittingbourne’s size, shops and offices often occupy older buildings with later extensions and new shopfronts. Where old meets new there are junctions between brick, render, timber and aluminium, and each needs the right sealant, in a colour that suits the frontage.

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 spell out the cover before we begin.

When to call us in Sittingbourne

When frames are recoated or a space is rebranded, the old joints may no longer suit. Refurbishments and rebrands often bring a new colour scheme.

Clients typically get in touch after noticing something like this:

  • A bead that fights the cladding or frame colour
  • Hotel refurbishments with a set colour scheme
  • Dirty, discoloured joints in public areas
  • Joints that need to match a new RAL frame colour

For a hotel such as The Bull Hotel, less than half a mile to the south-east of Sittingbourne, the colour of a joint at the bar or the bath matters to the look of the room.

  • Whether old or failed sealant will be cut out, not overlaid
  • Will RAMS and insurance details be available?
  • The named product and why it was chosen

How to choose a sealant contractor

Quoting for work in Sittingbourne

Each job is priced on its own details. The things that drive the figure:

  • Removal of failed or old sealant
  • How much there is to seal
  • Whether the work must be split into stages
  • How accessible the joints are

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Access details, including height
  • A wide shot and a close-up of the area
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

For a fixed quote, speak to us on 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.

On site: what to expect

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For a town like Sittingbourne, we try to group jobs for the same client into one visit, with one quote covering them. Tell us when the building is open and we will plan to suit.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photos of the finish are checked against the product’s range.
  3. A short trial length can be approved before the full run on visible work.
  4. We take out the existing bead, clean the joints and fit backing.
  5. The coloured sealant is applied and tooled with clean, masked edges.

Before we start on site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

Your questions answered

Does the sea air around Sittingbourne change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Will our hotel in Sittingbourne need to close for the work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Can staff carry on working while you’re here?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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. We don’t remove asbestos-containing materials.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Record the product and colour reference on the building file
  • Keep the same sealant colour across a brand
  • Approve a sample bead on high-profile areas
  • Insist on the agreed colour for any repair

Use gentle cleaning methods on coloured sealant. Harsh chemicals and scouring can change how the colour looks over time.

Standardise the sealant colour on multi-site work. It keeps repairs and new sites consistent.

Commercial clients in Sittingbourne

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Coloured sealant around Sittingbourne: what changes locally

The sea is no more than about 2 miles from Sittingbourne. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. We choose a product rated for the exposure, then confirm the colours available for it. The area within 2 miles of Sittingbourne holds a number of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, and the work can be phased so the rest of the hotel keeps trading.

Shops and cafés around stations like Sittingbourne station, less than half a mile south of Sittingbourne, trade from early, so work is timed around them. A business with units at Kent Science Park and Newington Enterprise Centre needn’t use two contractors for its sealant.

What happens if it’s left?

A mismatched or discoloured bead is a small detail that buyers, guests and clients notice, especially in shop fits and hotels. Putting it right costs little compared with the finishes around it. In a town like Sittingbourne, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
