Coloured sealant for Bow sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Coloured sealant in Bow, done properly

Shop fits, hotels and offices are where colour-matched sealant earns its place. A grey bead on a black shopfront or a white line against oak looks like a defect, even when the seal is sound. We pick a colour from the product’s range that sits with the finish. If you’re dealing with sealant that no longer suits recoated frames and failed coloured sealant that has split or peeled, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Bow it comes down to the same thing: the right product in a properly prepared joint.

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. The right product goes on each, in a colour chosen to suit where the joint is seen.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we’ll come back to it.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Repairing damaged frames or cladding
  • Paint over sealant on joints that move too much
  • A guaranteed perfect match to every finish

Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Joints and surfaces we work on

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

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Commercial premises in Bow

17 care or nursing homes sit less than 2 miles from Bow. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms. There are a good number of hotels within about 2 miles of Bow. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme; work is planned so the hotel keeps trading.

Sites a few miles apart, such as Old Ford Trading Estate and Stour Road Industrial Estate, can share one programme and one point of contact. Shops and cafés around stations like Hackney Wick station, 0.9 miles north of Bow, trade from early, so work is timed around them. Trade counters and showrooms on estates such as Old Ford Trading Estate (to the north-east of Bow) need neat joints where customers see them.

Bow is about 1 mile south-east of Hackney, in Greater London. Bow sits inside our coverage and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Across Greater London, 764 places are covered, Bow among them.

What affects the price in Bow

We price every job individually. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • Any access equipment needed
  • Backing rod, priming and other preparation
  • The product specified

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.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • The type of building and who uses it
  • Access details, including height
  • Where the site is, with the postcode

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Common questions from Bow clients

Must a hotel around Bow close while you work?

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

Can you work at a site such as Old Ford Trading Estate, by Bow?

Yes, sites like Old Ford Trading Estate are within our area, along with the rest of Bow. A few photos and the unit address let us price the work.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Can wet areas have colour-matched sealant?

Yes. Wet-area sealants are made in colours as well as white. We will confirm what’s available for the specified product.

Does a coloured sealant perform differently from a standard one?

Performance comes from the sealant type and the installation. We choose the right product for the joint first and then pick from its colour range, installed in exactly the same way.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Surface by surface

Natural stone

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

Powder-coated and anodised frames

Metallic and anodised finishes are hard to match exactly with sealant. We will suggest the nearest standard colours so you can choose.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We confirm the product the joint needs before talking about colour.
  2. We compare your RAL reference or sample with the colours made for that sealant.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  4. We remove the existing bead, clean the faces and set the depth.
  5. The coloured sealant is applied and tooled with clean, masked edges.

Preparing the site

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached

Request a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or use the quote form.
