Coloured sealant for commercial buildings in Wembley

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. We work on hotel bathrooms and public areas, cladding panels and office fit-out finishes, and what we are called in for most is failed coloured sealant that has split or peeled and white or grey sealant that clashes with the finish. A single leaking joint is often how a building in Wembley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around Wembley, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. The right product goes on each, in a colour chosen to suit where the joint is seen.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Building owners, agents and FMs in Wembley

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Preventing all fading from sunlight and weathering
  • Paintable products in joints they aren’t suited to
  • Exact bespoke colour matches beyond the product’s range

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

What we seal

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

Different surfaces, different methods

Cladding panels

Panel joints form a grid on the facade, so colour matters. The colour is picked from the range of a sealant that suits the panel joint, suited to the expected movement.

Hotel interiors

Phased work can be planned so areas stay in use. We plan around your occupancy with areas kept in use.

What happens if it’s left?

People notice sealant lines more than you might expect, particularly on high-end finishes. Resealing in a suitable colour is a modest cost against the finishes it sits beside. In Wembley, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

There’s no price list, since every building and every scope is different. Call for a quote.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a job in Wembley, access comes first. Give us the hours we can be on site and we’ll schedule to suit.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photos of the finish are checked against the product’s range.
  3. A short trial length can be approved before the full run on visible work.
  4. We remove the existing bead, clean the faces and set the depth.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Before we start on site

  • Move anything stored against the joints
  • Tell staff and tenants when we will be in
  • Point out any areas we must not close

Advice

Your questions answered

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

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.

Does your area include sites such as East Lane Business Park, near Wembley?

Yes. Estates, retail parks and business parks around Wembley, East Lane Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Does a coloured sealant perform differently from a standard one?

The product type decides performance, not the colour. We choose the right product for the joint first and then pick from its colour range.

Do you cover Wembley?

Yes. We cover Wembley and the rest of Greater London. To discuss a job, ring 01277 525 020 or use the quote form.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Clean coloured joints with mild products
  • Approve a sample bead on high-profile areas
  • Put the colour reference on the finishes schedule
  • Standardise colours across a portfolio

Keep a record of the product and colour reference used. It makes matching later repairs much easier.

Include coloured joints in a planned maintenance cycle. Replacing them on a schedule keeps finishes looking right across the building.

What Wembley’s businesses ask us to seal

Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We fit into those systems and phase the work so the building keeps operating. There are two care or nursing homes within about 2 miles of Wembley. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean, often in colours that suit the décor.

With Wembley inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site. Occupiers with premises at both East Lane Business Park and Stadium Retail Park could have the sealant at each handled under one quote. For a hotel such as OYO The Green Man Pub And Hotel, under half a mile south-east of Wembley, the colour of a joint at the bar or the bath matters to the look of the room.

Wembley is about 5 miles west of Hampstead, in Greater London. We cover commercial sites throughout Wembley, whether it’s a single job or part of a planned programme. We work across 764 places in Greater London. We also cover London, around 10 miles from Wembley.
