Coloured sealant near Heron Quays

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

Work for main contractors and building owners

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

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Coloured sealant in Heron Quays

A coloured bead has to perform like any other sealant. Each joint is cleaned, backed to depth and tooled firmly onto both faces, with no shortcuts because it’s decorative. Careful masking keeps the edges crisp. If you’re dealing with dirty, discoloured joints in public areas and white or grey sealant that clashes with the finish, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Heron Quays, that means joint design, primers and backing rod as standard.

Buildings in a London area such as Heron Quays rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us, and where a brand finish matters, the sealant colour is agreed first.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Stopping sealant from ever changing colour outdoors
  • Cleaning or repairing the surrounding finishes
  • Colour variation across natural stone or brick that no single shade can match

If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.

What we seal

  • Natural stone and brick
  • Cladding panels

  • Powder-coated and anodised frames
  • Office fit-out finishes

Questions about Heron Quays

Does your area include sites such as Poplar Business Park, near Heron Quays?

Yes. Estates, retail parks and business parks around Heron Quays, Poplar Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Can you work in a London building with booked loading and goods-lift slots?

Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Is Heron Quays in your area?

Yes. Heron Quays falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email drawings and photos.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Surface by surface

Brick and masonry

Vertical movement joints run the full height of many brick walls. A well-chosen colour helps them blend in while the product still suits the movement.

Natural stone

Sandstone, limestone and granite each have distinct tones. Colour is agreed on site where possible after a sample if needed.

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 move on in phases so staff and visitors can carry on around us. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. The programme and access are agreed, including any phasing.
  4. We prepare each joint, prime where needed and fit backing.
  5. The agreed colour is installed and tooled neatly.

Getting the site ready

  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

When to call us in Heron Quays

A change of finish can leave existing sealant mismatched. Refurbishments and rebrands often bring a new colour scheme that the sealant has to follow.

If one of these sounds familiar, it’s time for a closer look:

  • Hotel refurbishments with a set colour scheme
  • A run of joints in mismatched shades
  • Smeared sealant on stone or joinery
  • Old colour-matched joints lifting at the edges

A hotel such as Hotel Britannia International (to the south of Heron Quays) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

What affects the price in Heron Quays

Quotes vary with the job. Expect it to depend on:

  • Quantities, in metres or numbers
  • Working within restricted access windows
  • Travel to remote or island sites
  • Any access equipment needed

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • Asbestos survey details if the building is older
  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • When you need the work done

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
