Coloured sealant in Angel

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What affects the price in Angel

Before we quote, we look at:

  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits
  • Joint width, depth and condition

A quote for colour-matched joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Send us:

  • Any dates the work must fit around
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Coloured sealant in Angel

Shop fits, hotels and offices are where colour-matched sealant earns its place. A mismatched bead can make good joinery look unfinished. The aim is a colour from the product’s range that disappears into the surface. We work on shop-fit joinery and counters, cladding panels and hotel bathrooms and public areas, and what we are called in for most is a run of joints in mismatched shades and hotel refurbishments with a set colour scheme. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Angel it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Surface by surface

Powder-coated and anodised frames

Frames finished to a RAL reference are a frequent colour-matching job. We compare the reference with the specified product’s colour range, and the nearest option is agreed.

Office fit-outs

In offices, sealant appears at partitions, tea points, washrooms and reception desks. A consistent colour across floors looks deliberate.

On site: what to expect

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 the job ends with a walk round and sign-off. Planning a London job such as one in Angel starts with access. Send the building rules and access times with your enquiry.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. Tell us your site hours and access windows and we will plan around them.
  4. Joints are prepared, primed where specified and backed.
  5. We seal in the approved colour and tool it smooth.

Preparing the site

  • Arrange parking or a loading space
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Ask for a quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or send details through our quote form.

Related advice

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Check a trial length in real light
  • Keep the area clear while the sealant cures
  • Don’t let trades patch coloured joints with a random sealant
  • Agree the sealant colour early and write it into the specification

Colours can soften with light and weathering. That is normal for exposed sealant, and resealing restores the look when the time comes.

Approve a sample where colour really matters. Seeing the cured colour in place avoids surprises.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Materials with mixed tones that defy a single match
  • Restoring stained stone or masonry next to old sealant
  • Custom-mixed sealant colours

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

  • Natural stone and brick

  • Office fit-out finishes

Do you need coloured sealant in Angel?

Most enquiries start with a joint that looks wrong: a pale bead on a dark frame, or an old seal that has discoloured. A better-matched colour fixes the appearance without changing the joint’s job.

Look out for the following:

  • Weathered sealant that no longer matches
  • Hotel refurbishments with a set colour scheme
  • Sealant that no longer suits recoated frames
  • White or grey sealant that clashes with the finish

Shops and cafés around stations like London Kings Cross station (0.7 miles west of Angel) trade from early, so work is timed around them.

What your quote should include

  • What level of public liability insurance do they hold?
  • Are they CHAS accredited or on Constructionline?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What site paperwork they can supply

Choosing a commercial sealant contractor

Angel: questions and answers

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

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

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

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Does coloured sealant change colour outdoors?

Exposed sealant can change in appearance over the years. Sunlight, dirt and weathering affect how it looks, which is why exposed joints are inspected and resealed when needed.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Do you do a sample bead?

Yes. Where colour is critical, we can agree a short sample bead in a discreet spot. Cured sealant can look slightly different from the wet bead, so it’s worth checking in real light.

Coloured sealant around Angel: how the place shapes the job

A 2-mile radius around Angel takes in a good number of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme. Three care or nursing homes sit less than 2 miles from Angel. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean, often in colours that suit the décor.

In a retail centre such as Brunswick Centre, 0.9 miles to the south-west of Angel, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. In hotels such as Swinton Hotel (0.5 miles south-west of Angel), refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.
