Coloured sealant for Old Tree sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Coloured sealant in Old Tree, done properly

Where colour is critical, a sample bead in a discreet spot settles the question. Sealant can look slightly different once it has cured, and again in different light, so seeing it in place helps. Tell us who needs to approve the colour and we will plan for it. If you’re dealing with hotel refurbishments with a set colour scheme and white or grey sealant that clashes with the finish, we can put it right, on cladding panels, powder-coated and anodised frames and hotel bathrooms and public areas alike. Most enquiries from Old Tree start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Business units in the countryside around places like Old Tree 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us.

  1. Photos or drawings show us the finishes and joints.
  2. Colour options from the specified product’s range are shared with you.
  3. Tell us your site hours and access windows and we will plan around them.
  4. We prepare each joint, prime where needed and fit backing.
  5. We seal in the approved colour and tool it smooth.

Advice

Your questions answered

Does the sea air around Old Tree 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. We check the specified product suits the exposure and pay close attention to preparation.

Is a smaller place like Old Tree outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can we see a sample before the full job?

Yes. Tell us who approves colour and we will plan the sample into the programme before the main run.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Will sunlight affect the sealant colour?

Some change over time is normal. How much depends on the product, the colour and the exposure, so no colour stays exactly the same for ever.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

What Old Tree’s businesses ask us to seal

Old Tree sits close to the coast, within about 3 miles. 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. Old Tree sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

Premises within reach of Herne Bay station, 2.9 miles north-west of Old Tree, often have busy frontages where joints are seen by everyone passing. On a business park such as Chislet Business Park, which lies south of Old Tree, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Old Tree is about 3 miles south-east of Herne Bay, in Kent. We send applicators to Old Tree for colour-matched joints. 931 places across Kent fall within our area, including Old Tree. Sites around London have their own page, roughly 56 miles from Old Tree.

We cover the CT3 postcode districts. We also cover Maypole (1 mile west), Hoath (1 mile south-west), Millbank (1 mile north-west), Knave's Ash (1 mile south-west) and Hollow Street (1 mile south-east) for colour-matched joints. A short drive away, we cover Canterbury (6 miles south-west), Margate (10 miles east), Dover (15 miles south), Ramsgate (10 miles east), Broadstairs (11 miles east) and Whitstable (6 miles west).

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Old Tree can form part of a wider programme.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Signs you need coloured sealant in Old Tree

Internal joints can stain from cleaning products, spills or mould. Mould that has rooted into a bead rarely cleans out, so the joint is replaced.

Site and facilities staff are often the first to spot these:

  • Shop fits that need consistent sealant colours across sites
  • Poorly tooled joints on visible finishes
  • Standard-colour sealant spoiling a high-end finish
  • A run of joints in mismatched shades

A business with units at Chislet Business Park and Canterbury Industrial Park needn’t use two contractors for its sealant.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

General trades versus a specialist

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What happens if it’s left?

Matching new joints to the existing ones is easier when the whole run is done together. Piecemeal repairs over several years tend to drift in colour. Converted and older buildings near places like Old Tree tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Site requirements such as inductions and permits
  • The size and state of each joint
  • How accessible the joints are
  • Working within restricted access windows

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • The asbestos register, for older buildings
  • The type of building and who uses it
  • The site address and postcode
  • Drawings or a marked-up plan, if available

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
