Coloured sealant across Spitalfields

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

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a job in Spitalfields, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

Preparing the site

  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification
  • Move anything stored against the joints

Advice

Coloured sealant for commercial buildings in Spitalfields

A coloured bead has to perform like any other sealant. Faces are prepared, depth is fixed with rod and the bead is tooled onto two sides only. Careful masking keeps the edges crisp. We work on powder-coated and anodised frames, natural stone and brick and cladding panels, and the usual reasons a site gets in touch are sealant that no longer suits recoated frames and failed coloured sealant that has split or peeled. Looking for mastic applicators who cover Spitalfields? We have been sealing commercial buildings since 2005.

Around Spitalfields, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Preventing all fading from sunlight and weathering
  • Exact bespoke colour matches beyond the product’s range
  • Materials with mixed tones that defy a single match

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

What we seal

  • Powder-coated and anodised frames
  • Hotel bathrooms and public areas
  • Cladding panels
  • Shop-fit joinery and counters
  • Natural stone and brick
  • Office fit-out finishes

Leave it or put it right?

Agreeing the colour before work starts avoids paying twice. A short trial bead costs very little against redoing a whole elevation. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

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

Signs you need coloured sealant in Spitalfields

Colour-matched sealant is usually requested because a standard bead has spoiled the finish: a pale bead on a dark frame, or an old seal that has discoloured. Replacing it with a suitable colour restores the intended look.

What tends to prompt an enquiry:

  • Poorly tooled joints on visible finishes
  • Fit-outs with a sealant colour in the specification
  • Joints that need to match a new RAL frame colour
  • Failed coloured sealant that has split or peeled

Sites a few miles apart, such as Princes Court Business Centre and Anchor Retail Park, can share one programme and one point of contact.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • How the joint faces will be prepared and primed
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Working on commercial sites near Spitalfields

Spitalfields has a good number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes. London premises typically come with a building manager, booked loading and house rules for contractors. We plan around them and agree phasing so tenants and customers aren’t disrupted.

If you run an office at a site such as Princes Court Business Centre, 0.9 miles to the south-east of Spitalfields, the sealant at reception desks, tea points and frames ages with each fit-out. Access in Spitalfields needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple.

Your questions answered

Do you take on jobs in Spitalfields where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

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

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Does a coloured sealant perform differently from a standard one?

The product type decides performance, not the colour. The joint gets the product it needs, in a colour from that product’s range, installed in exactly the same way.

Can staff carry on working while you are here?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

What hours do you work?

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.
