Coloured sealant across Staples Corner

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

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Whether old sealant has to be cut out first
  • The product specified
  • Any access equipment needed
  • Location, for remote and island sites

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • How the joints are reached, and at what height

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or send details through our quote form.

Coloured sealant in Staples Corner, done properly

A colour-matched bead still has to work as a seal. Each joint is cleaned, backed to depth and tooled firmly onto both faces, exactly as for a standard colour. Careful masking keeps the edges crisp. We work on natural stone and brick, hotel bathrooms and public areas and cladding panels, and what we are called in for most is standard-colour sealant spoiling a high-end finish and patch repairs in several different colours. Most enquiries from Staples Corner start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Around Staples Corner, 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.

Every job we finish is backed by a 12-month workmanship guarantee, in Staples Corner as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Different surfaces, different methods

Natural stone

Stone facades and stone interiors vary widely. Colour is agreed on site where possible before the full run.

Shop-fit and joinery finishes

Counters, display units and wall linings are seen close up. A sharp, even bead is as important as the colour.

Coloured sealant around Staples Corner: what changes locally

Three care or nursing homes sit less than 2 miles from Staples Corner. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. Our planning starts from those rules rather than working round them later.

Retail sites such as Brent Cross Shopping Park, under half a mile to the east of Staples Corner, are typical of where shop-fit joints, frontages and staff areas need neat, colour-matched sealant. A business with units at Brent Cross Shopping Park and Silk Bridge Retail Park needn’t use two contractors for its sealant.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Exact bespoke colour matches beyond the product’s range
  • Colour variation across natural stone or brick that no single shade can match
  • Overpainting a joint that needs a non-paintable product

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

What we seal

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

Common problems we fix in Staples Corner

Exposure takes its toll on colour. UV, grime and weathering alter how a bead looks after a few years. A reseal brings the colour back in line.

Clients usually get in touch after noticing one or more of the following:

  • Smeared sealant on stone or joinery
  • Shop fits that need consistent sealant colours across sites
  • Colour changes after a rebrand or refit
  • Patch repairs in several different colours

Shops and cafés around stations like Brent Cross West station, less than half a mile to the south of Staples Corner, trade from early, so work is timed around them.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Will failed sealant be removed rather than covered?
  • Their public liability cover
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Our process

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Planning a London job such as one in Staples Corner starts with access. Send the building rules and access times with your enquiry.

  1. We confirm the joint type and the product it needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  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.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Tell us which areas need to stay in use

Related advice

Site staff or a sealant specialist?

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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

Staples Corner: questions and answers

Do hotels near Staples Corner have to close for sealant work?

In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

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. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Can you match any colour exactly?

No, not in every case. We choose the nearest standard colour and a sample can be approved before the full run.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
