Coloured sealant near Thong

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Thong are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We confirm the joint type and the product it needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. You approve the colour, on site if it’s critical.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. We remove the masking and walk the finished joints with you.

What we need from you

  • Move anything stored against the joints
  • Share the asbestos register for older buildings
  • Tell us what induction or permit system the site runs

Advice

Coloured sealant in Thong

Natural materials vary across a single elevation: a stone or brick facade shifts in tone from one area to the next. We choose a colour that reads well across the surface rather than chasing one spot. We work on office fit-out finishes, natural stone and brick and powder-coated and anodised frames, and the failures we are asked to look at most are failed coloured sealant that has split or peeled and old sealant that has yellowed, darkened or faded. Whoever orders the work in Thong, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Commercial sealant work around smaller places like Thong tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

What affects the price in Thong

Before we quote, we look at:

  • How much existing material needs removing
  • Access and working height
  • How much there is to seal
  • The size and state of each joint

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Sending details for a quote

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

  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work
  • When you need the work done

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Coloured sealant in Thong: the local picture

Thong lies within about 3 miles of the sea. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. Where a frontage needs a particular colour, the product still has to suit that exposure. There are several hotels within about 2 miles of Thong. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet; work is planned so the hotel keeps trading.

In a retail centre such as Imperial Retail Park (2.9 miles north-west of Thong), new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. For premises near Sole Street station, 2.2 miles south-west of Thong, footfall is part of the plan: work is phased so shops and offices keep trading. Sites a few miles apart, such as Lion Business Park and Canal Industrial Park, can share one programme and one point of contact.

Thong is about 2 miles south-east of Gravesend, in Kent. Thong sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 931 places in Kent. London is covered too, some 22 miles away.

Anyone looking for coloured sealant in DA12 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside Thong, we cover Upper Ifield (1 mile east), Shorne Ridgeway (1 mile east), Shorne (1 mile east), Chalk (1 mile north) and Higham (2 miles east). Further afield, our area takes in Maidstone (11 miles south-east), Sittingbourne (15 miles east), Dartford (8 miles west), Sevenoaks (13 miles south-west), Northfleet (3 miles north-west) and Swanley (10 miles west).

Near you in Thong

We work on buildings around Shorne Woods Country Park and Thamesview School. Thong’s nearest station is Sole Street station, about 2.2 miles south-west of the centre. Other landmarks nearby include Rochester Castle (4.5 miles east) and Gravesham Museum (2.6 miles north-west). For a walk, there’s Rede Common and Gad's Hill.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units 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.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Thong can sit alongside others in a wider programme across Kent.

Questions about Thong

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

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we’ll plan around them.

Is Lion Business Park, near Thong, within your area?

Yes. Estates, retail parks and business parks around Thong, Lion Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes a day for a modest shop fit, and longer for a full building or several floors. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you take on colour-matched sealant for shop fits and multi-site roll-outs?

Yes. Send the specification or colour reference for a quick quote. Tell us your site hours and access windows and we will plan around them.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Check a trial length in real light
  • Standardise colours across a portfolio
  • Avoid abrasive pads on coloured sealant
  • Note which sealant colour was used where

Let the joints cure as the manufacturer advises before they’re cleaned. Coloured sealant marks more visibly than white while it is fresh, so keep the area clear.

Share the colour reference with anyone working on the finishes. It stops mismatched repairs creeping in.

Why act early in Thong

Leaving a failed coloured joint risks more than appearance. Water through a split seal can stain or damage the surfaces next to it. Halls, stores and units around places like Thong may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why us?

  • Old sealant cut out, never sealed over
  • Fixed quotes based on photos, drawings or a visit
