Coloured sealant in West Silvertown

Coloured sealant is a finishing trade, so it usually comes late in a programme. We work around other trades and protect adjacent finishes. A 12-month guarantee covers our workmanship. We work on natural stone and brick, hotel bathrooms and public areas and shop-fit joinery and counters, and the usual reasons a site gets in touch are discoloured joints on a visible elevation and old colour-matched joints lifting at the edges. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in West Silvertown it comes down to the same thing: the right product in a properly prepared joint.

For managing agents and FMs looking after premises in West Silvertown, access is usually the first question: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work

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
  • Keep harsh solvents away from visible joints
  • Brief cleaners about newly sealed joints
  • Avoid piecemeal repairs on coloured joints

Check visible joints during routine inspections. Look for splits, lifting edges and staining and deal with problems early.

Put the sealant colour into the specification or finishes schedule. Late decisions lead to substitutes and mismatches.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Custom-mixed sealant colours
  • Stopping sealant from ever changing colour outdoors
  • Materials with mixed tones that defy a single match

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photos 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.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed

Why deal with it now?

A brand roll-out or multi-site fit-out benefits from a consistent sealant colour. Setting one product and colour for every site avoids variation across the programme. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Why us?

  • Commercial sealant work since 2005
  • RAL and finish matching where the product range allows
  • Failed material removed, not covered up
  • Standard and matched colours in many product ranges

FAQs: West Silvertown

Can you cope with the access rules in a London building?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

Does your area include sites such as Greenshields Industrial Estate, near West Silvertown?

Yes. We cover West Silvertown and the area around it, including industrial estates, business parks and retail parks such as Greenshields Industrial Estate. A few photographs and the unit address let us price the work.

Does weather matter for sealant work?

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

Does coloured sealant change colour outdoors?

Some change over time is normal. Exposure, product and colour all play a part, and we can’t promise a colour that never alters.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How the quote is worked out

Before we quote, we look at:

  • How much existing material needs removing
  • Location, for remote and island sites
  • The site’s rules and procedures
  • Any access equipment needed

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Before you send an enquiry

However big the job, these details speed things up:

  • Anything awkward about access or site hours
  • The product your specification calls for
  • Whether an asbestos survey exists
  • The type of building and who uses it

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email a schedule or drawings.
