How we handle coloured sealant in Keycol

Where colour is critical, a sample bead in a discreet spot settles the question. Cured sealant may look a shade different from the wet bead, and lighting changes it again, so seeing it in place helps. Tell us who needs to approve the colour and we will plan for it. We work on hotel bathrooms and public areas, cladding panels and natural stone and brick, and what we are called in for most is discoloured joints on a visible elevation and dirty, discoloured joints in public areas. Whoever orders the work in Keycol, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places such as Keycol, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Keycol need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We confirm the joint type and the product it needs.
  2. We compare the target colour with the colours available.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

Preparing the site

  • Explain the parking and delivery arrangements
  • 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.

Owners, agents and contractors

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

What sets the cost

To price the job, we consider:

  • The product specified
  • Site requirements such as inductions and permits
  • The total length or number of joints
  • Whether the work must be split into stages

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • The product your specification calls for
  • Clear photos of the problem areas
  • Your programme or deadline
  • Drawings or a marked-up plan, if available

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or email drawings and photos.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What the job involves on each surface

Cladding panels

Where panels vary in colour, the joint colour is agreed for the whole elevation. Sometimes a mid-tone suits better than matching one panel, and a sample settles it.

Natural stone

Sandstone, limestone and granite each have distinct tones. We choose from the product’s range and agree the colour with you before the full run.

Frontages, fit-outs and joints in Keycol

The sea is no more than about 3 miles from Keycol. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. We choose a product rated for the exposure, then confirm the colours available for it. Keycol 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.

Offices at parks like Newington Enterprise Centre, 1 mile to the north-west of Keycol, have receptions, kitchens and glazed partitions where a tidy joint matters. Offices and shops close to stations such as Newington station (to the west of Keycol) tend to be busy all day, so sealant work is planned around opening hours.

Keycol is about 2 miles west of Sittingbourne, in Kent. We send applicators to Keycol for colour-matched joints. Our Kent coverage takes in 931 places. Our London page has more on work in that area, about 35 miles away.

FAQs: Keycol

Does a coastal location like Keycol affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Do hotels near Keycol have to close for sealant 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.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Can you guarantee a perfect colour match?

No. We can’t promise an exact custom match. We’ll show you the closest colours in the specified product’s range so you can choose.

What we’re called out for in Keycol

Sometimes the wrong colour went in at the start, or a different product was swapped in. It seals fine but catches the eye, so someone asks for it to be changed.

Things that usually lead to an enquiry:

  • Weathered sealant that no longer matches
  • Failed coloured sealant that has split or peeled
  • Dirty, discoloured joints in public areas
  • Smeared sealant on stone or joinery

Sites a few miles apart, such as Newington Enterprise Centre and Newington Industrial Estate, can share one programme and one point of contact.

Questions to ask before you book

  • How joint depth will be controlled
  • Can the work be phased to keep areas open?
  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
