Coloured sealant for businesses in Soho

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Looking after the joints

For the best life from the joints:

  • Brief cleaners about newly sealed joints
  • Note which sealant colour was used where
  • Don’t let trades patch coloured joints with a random sealant
  • Use one colour standard across multi-site work

Don’t let anyone patch a coloured joint with whatever sealant is to hand. A mismatched repair stands out.

Ask for a trial bead on high-profile areas. A sample in real light shows how it will look.

Coloured sealant in Soho

Where colour is critical, a sample bead in a discreet spot settles the question. Cured sealant may look a shade different from the wet bead, and lighting changes it again, so seeing it in place helps. Tell us who needs to approve the colour and we’ll plan for it. We work on hotel bathrooms and public areas, powder-coated and anodised frames and natural stone and brick, and what we’re called in for most is poorly tooled joints on visible finishes and marked sealant in hotel bathrooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Soho is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Buildings in a London area such as Soho 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Soho: questions and answers

Do you cover business parks and estates near Soho, such as Grand Vitesse Industrial Estate?

Yes. We cover Soho and the area around it, including industrial estates, business parks and retail parks such as Grand Vitesse Industrial Estate. A few photos and the unit address let us price the work.

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. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

Do you work on hotel and retail fit-outs?

Yes. We work with shop fitters, hotel groups and office fit-out contractors. Our area takes in Greater London, the South East and Scotland, so a consistent colour can run across several sites.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What do you charge?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Can you match any colour exactly?

No. An exact bespoke match isn’t something we can promise. Sealants come in a wide range of standard colours, and we’ll confirm the colours available for the specified product.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

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.

Hotel interiors

Hotels use colour-matched sealant in bathrooms, bedrooms and public areas. Wet-area sealants come in colours other than white too, including shades for tiled and stone bathrooms.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In Soho, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  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. The existing bead comes out, then faces are cleaned and backed.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows
  • Share the asbestos register for older buildings

Coloured sealant in Soho: the local picture

Less than 3 miles from Soho there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it. The area within 2 miles of Soho holds a good number of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, and the work can be phased so the rest of the hotel keeps trading.

In hotels such as The Piccadilly London West End Hotel, which lies south-west of Soho, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. A business with units at Grand Vitesse Industrial Estate and Southwark Bridge Business Centre needn’t use two contractors for its sealant. Trade counters and showrooms on estates such as Grand Vitesse Industrial Estate, 1.4 miles to the south-east of Soho, need neat joints where clients see them.

Soho is about 1 mile east of City of Westminster, in Greater London. We cover Soho and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 764 places across Greater London fall within our area, including Soho.

Work on colour-matched joints is covered throughout W1F, W1T and W1D, for business premises of every kind. Among the streets we cover are Duck Lane, Drury Lane and Bridle Lane, and sites on any of them can send details for a fixed quote. You will find Soho on or near the A4 and A301, so getting applicators and materials to site is simple. We also cover West End (1 mile east), Chinatown (1 mile south), Seven Dials (1 mile east), St Giles (1 mile north-east) and St James's (1 mile south) for colour-matched joints. Further afield, our area takes in Kensington (3 miles west), Walthamstow (7 miles north-east), Whitechapel (3 miles east), Hampstead (3 miles north-west), Ruislip (13 miles west) and Stockwell (3 miles south).

Landmarks near Soho

We work on buildings around Bar Soho, St Anne's Churchyard and Harris Westminster Sixth Form and the streets around them. Nearby too are LITE Regal International School (0.6 miles west) and London Library (0.5 miles south-west). Soho has its own railway station: Tottenham Court Road station. Nearby you will also find Kingly Court (under half a mile west) and Montfichet's Tower (1.3 miles east). Open spaces near Soho include St. James's Park Lake and Ludgate Hill.

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Soho. Several sites can go on one quote, which keeps the paperwork simple.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Soho can form part of a wider programme across Greater London.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What sealant work can’t fix

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

  • Preventing all fading from sunlight and weathering
  • Overpainting a joint that needs a non-paintable product
  • Colour variation across natural stone or brick that no single shade can match

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think.
