Coloured sealant near Shadwell

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

Different surfaces, different methods

Shop-fit and joinery finishes

In shops, joints are at eye level and inspected by customers. A sharp, even bead is as important as the colour.

Hotel interiors

In hotels, sealant shows in rooms, bathrooms and front-of-house. Sanitary silicone comes in colours too.

Coloured sealant in Shadwell

Stone, brick and cladding each bring their own colour challenge: a stone or brick facade shifts in tone from one area to the next. The aim is a sealant colour that sits comfortably against the whole surface, with a sample on site if colour is critical. We work on shop-fit joinery and counters, powder-coated and anodised frames and hotel bathrooms and public areas, and what we’re called in for most is a run of joints in mismatched shades and marked sealant in hotel bathrooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Shadwell is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

London’s commercial stock mixes period buildings turned into offices with modern glass and steel, 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.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Building owners, agents and FMs in Shadwell

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

What affects the price in Shadwell

The price varies from site to site. Expect it to depend on:

  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • Specialist products, such as fire-rated or hygienic sealants
  • Location, for remote and island sites

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • The site address and postcode
  • A wide shot and a close-up of the area
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos to discuss it first.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Shadwell, 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. Photos or drawings show us the finishes and joints.
  2. Colour options from the specified product’s range are shared with you.
  3. Tell us your site hours and access windows and we’ll plan around them.
  4. Joints are prepared, primed where specified and backed.
  5. The agreed colour is installed and tooled neatly.

Before we start on site

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Share your working hours and any access restrictions

Sealant on show in Shadwell’s commercial buildings

Shadwell has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal. Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We work within them, one zone at a time.

On a business park such as Princes Court Business Centre, 0.5 miles west of Shadwell, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. In hotels such as Dockside Hotel, 0.5 miles north-west of Shadwell, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Premises within reach of Wapping station, less than half a mile south-west of Shadwell, often have busy frontages where joints are seen by everyone passing.

Questions about Shadwell

Does a hotel in Shadwell need to shut while its sealant is renewed?

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.

Do you work in London buildings with loading restrictions?

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. All of Greater London is inside the ULEZ, and our planning allows for it

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Can you work to a RAL reference?

Yes. RAL references are a common way to specify sealant colour. We check what that product is made in and agree the nearest option.

Can wet areas have colour-matched sealant?

Yes, in many cases. Hotel bathrooms, washrooms and kitchens often use coloured sanitary silicone to suit tiles or stone.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Paint over sealant on joints that move too much
  • Colour variation across natural stone or brick that no single shade can match
  • Custom-mixed sealant colours

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think.
