Coloured sealant near Broadfields Estate

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

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Plan full-run reseals on visible elevations
  • Keep the area clear while the sealant cures
  • Don’t let trades patch coloured joints with a random sealant
  • Check a trial length in real light

If other trades disturb a coloured joint, ask them to tell you rather than patch it. A mismatched repair stands out, so it is better to reseal the section properly.

Standardise the sealant colour on multi-site work. Consistency makes future work simpler and easier to manage.

Coloured sealant for commercial buildings in Broadfields Estate

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. The aim is a colour from the product’s range that disappears into the surface. We work on natural stone and brick, hotel bathrooms and public areas and shop-fit joinery and counters, and the failures we’re asked to look at most are a bead that fights the cladding or frame colour and shop fits that need consistent sealant colours across sites. A single leaking joint is often how a building in Broadfields Estate 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.

For managing agents and FMs looking after premises in Broadfields Estate, access is usually the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the colour-matched joints are resealed in sections so tenants are disturbed as little as possible.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Finishes that change colour from one area to another
  • Repairing damaged frames or cladding
  • A guaranteed perfect match to every finish

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think.

Surfaces we seal

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

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For managing agents and facilities managers

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.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Why deal with it now?

Leaving a failed coloured joint risks more than appearance. Behind the bead, moisture can damage substrates and finishes, so it’s worth fixing early. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. 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. 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 take out the existing bead, clean the joints and fit backing.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Getting the site ready

  • Point out any areas we must not close
  • Tell staff and tenants when we’ll be in
  • Explain the parking and delivery arrangements
