About our coloured sealant in Brasted

Colour is often written into the specification, by RAL reference or by matching a sample. Standard sealant ranges cover many colours, so we check what the specified product is made in. We don’t promise an exact custom match, but we will show you the closest options. The enquiries we see most involve poorly tooled joints on visible finishes and weathered sealant that no longer matches, on powder-coated and anodised frames, shop-fit joinery and counters and office fit-out finishes. For commercial sealant work in Brasted, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Business units in the countryside around places like Brasted are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

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.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Brasted may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photographs 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 remove the existing bead, clean the faces and set the depth.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Before we start on site

  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions
  • Let us know about inductions and permits

What sets the cost

To price the job, we consider:

  • Location, for remote and island sites
  • Backing rod, priming and other preparation
  • Working within restricted access windows
  • How much there is to seal

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • Any dates the work must fit around
  • The postcode of the building
  • How the joints are reached, and at what height
  • Specification clauses that apply

To get a fixed quote, call the office on 01277 525 020 or email drawings and photos. You can also send details through our quote form.

What happens if it’s left?

People notice sealant lines more than you might expect, especially in shop fits and hotels. Resealing in a suitable colour is a modest cost against the finishes it sits beside, and it lifts the whole area. Older rural buildings around Brasted move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why clients in Brasted choose us

  • Failed material removed, not covered up

Different surfaces, different methods

Natural stone

Stone has variation, so the aim is a colour that sits naturally against it. A stone-safe neutral-cure product is used in the closest available colour.

Powder-coated and anodised frames

Anodised and metallic frames rarely have an identical sealant colour. We’ll suggest the nearest standard colours so you can choose.

Common questions from Brasted clients

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

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Does your area include sites such as Salters Heath Business Centre, near Brasted?

Yes. Estates, retail parks and business parks around Brasted, Salters Heath Business Centre among them, are all within reach. A few photos and the unit address let us price the work.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.

Does a coloured sealant perform differently from a standard one?

The product type decides performance, not the colour. We choose the right product for the joint first and then pick from its colour range.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Note which sealant colour was used where
  • Don’t let trades patch coloured joints with a random sealant
  • Agree the sealant colour early and write it into the specification
  • Use one colour standard across multi-site work

Colours can soften with light and weathering. That is normal for exposed sealant, and resealing restores the look when the time comes.

Approve a sample where colour really matters. Seeing the cured colour in place avoids surprises.

Shops, offices and hotels in and around Brasted

Brasted is about 18 miles from central London. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. Brasted is in the South East, one of the UK’s drier regions. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

If you run an office at a site such as Salters Heath Business Centre (2.4 miles east of Brasted), the sealant at reception desks, tea points and frames ages with each fit-out. For premises near Dunton Green station (3.1 miles north-east of Brasted), footfall is part of the plan: work is phased so shops and offices keep trading.

Brasted is about 3 miles west of Sevenoaks, in Kent. Businesses, contractors and managing agents in Brasted can call on us for colour-matched joints. Across Kent, 931 places are covered, Brasted among them. Our London page has more on work in that area (18 miles or so).

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Paintable products in joints they aren’t suited to
  • Colour variation across natural stone or brick that no single shade can match
  • Restoring stained stone or masonry next to old sealant

If you are not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer.
