Coloured sealant across Highbury

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Coloured sealant in Highbury, done properly

Coloured sealant work ranges from a new shop fit to replacing failed joints on an existing building. When replacing old joints, the new colour usually has to match what’s already there, especially on a listed or high-profile elevation. If you’re dealing with joints that need to match a new RAL frame colour and coloured joints that have cracked with movement, we can put it right. Whoever orders the work in Highbury, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What Highbury’s businesses ask us 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. The area within 2 miles of Highbury holds a good number of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let.

Units at places like Arena Shopping Park, 1.7 miles to the north of Highbury, are refitted as brands change, and the joints have to suit each new scheme. Industrial estates such as Frogmore Industrial Estate, under half a mile north of Highbury, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Highbury is about 4 miles north-east of City of Westminster, in Greater London. Highbury sits inside our coverage and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Highbury is one of 764 places we cover in Greater London for colour-matched joints.

Work on colour-matched joints is covered throughout N1, N16 and N5. We cover commercial and managed buildings on Prah Road, Dove Road and Lough Road and the roads nearby. Access to Highbury is via the A1199 among other routes, so getting applicators and materials to site is simple. Nearby places we also cover include Newington Green (1 mile east), Mildmay (1 mile east), Canonbury (1 mile south-east), De Beauvoir Town (1 mile south-east) and Stoke Newington (1 mile north-east). A short drive away, we cover London (4 miles south), City of Westminster (4 miles south-west), Marylebone (3 miles south-west), Kensington (6 miles south-west), Walthamstow (4 miles north-east) and Whitechapel (3 miles south-east).

Landmarks near Highbury

We work on buildings around Highbury Fields, Musical Theatre Academy and The Snooty Fox pub. Highbury has its own railway station: Canonbury station. Other landmarks nearby include Arsenal Football Club Museum (0.6 miles north-west) and Montfichet's Tower (2.7 miles south). The countryside around Highbury includes Gillespie Park and Dartmouth Park Hill.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. 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. Photos or drawings show us the finishes and joints.
  2. Colour options from the specified product’s range are shared with you.
  3. The programme and access are agreed, including any phasing.
  4. Joints are prepared, primed where specified and backed.
  5. The agreed colour is installed and tooled neatly.

Before we start on site

  • Tell staff and tenants when we will be in
  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work

After the work

To get the most from the new sealant:

  • Avoid abrasive pads on coloured sealant
  • Agree the sealant colour early and write it into the specification
  • Look at the cured colour before the full run
  • Note which sealant colour was used where

Don’t let anyone patch a coloured joint with whatever sealant is to hand. A mismatched repair stands out, so it is better to reseal the section properly.

Settle the colour early in the project. When colour is left to the last minute, it is often wrong.

What sets the cost

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

  • Site requirements such as inductions and permits
  • Any access equipment needed
  • Backing rod, priming and other preparation
  • Location, for remote and island sites

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Your programme or deadline
  • The product your specification calls for
  • What the building is and how it’s used
  • A wide shot and a close-up of the area

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Questions we are asked in Highbury

Do hotels near Highbury have to close for sealant work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Do you work to architects’ specifications?

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

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

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.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Common problems we fix in Highbury

Mould and staining discolour coloured joints in some areas. Mould that has grown into sealant usually can’t be cleaned out, so the joint is replaced.

If one of these sounds familiar, it’s time for a closer look:

  • Discoloured joints on a visible elevation
  • Colour changes after a rebrand or refit
  • White or grey sealant that clashes with the finish
  • Poorly tooled joints on visible finishes

Offices and shops close to stations such as Canonbury station, less than half a mile south-east of Highbury, tend to be busy all day, so sealant work is planned around opening hours.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Can the work be phased to keep areas open?
  • Proof of insurance
  • Health and safety accreditation such as CHAS

Our contractor checklist

Why act early in Highbury

A mismatched or discoloured bead is a small detail that buyers, guests and clients notice, especially in shop fits and hotels. Resealing in a suitable colour is a modest cost against the finishes it sits beside, and it lifts the whole area. Getting scaffold, permits or access booked in Highbury takes effort, so it makes sense to deal with every failing joint while access is in place.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • Fully insured, including public liability cover
  • Joints cleaned back to sound surfaces
  • Specification-led, product-correct work
  • One number for every site we cover
