Coloured sealant for commercial buildings in East Wickham

We can agree a short trial length before the full run. Sealant can look slightly different once it has cured, and again in different light. Let us know who signs off colour, and we will fit the sample into the programme. The enquiries we see most involve old sealant that has yellowed, darkened or faded and failed coloured sealant that has split or peeled, across office fit-out finishes, natural stone and brick and powder-coated and anodised frames. Most enquiries from East Wickham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

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: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

For managing agents and facilities managers

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • A colour that never alters with age
  • Cleaning or repairing the surrounding finishes
  • Paint over sealant on joints that move too much

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly.

What we seal

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

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. In East Wickham, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  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.

What we need from you

  • For older buildings, check the asbestos register before work
  • Flag any permit to work we will need
  • Share your working hours and any access restrictions

FAQs: East Wickham

Can you work at a site such as Gateway Business Centre, by East Wickham?

Yes. Estates, retail parks and business parks around East Wickham, Gateway Business Centre among them, are all within reach. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.

Do you offer colour-matched sealant for buildings in East Wickham?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Plan full-run reseals on visible elevations
  • Approve a sample bead on high-profile areas
  • Put the colour reference on the finishes schedule
  • Insist on the agreed colour for any repair

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

Plan resealing of visible joints before they look tired. A planned reseal avoids a run of patch repairs over the years.

How the quote is worked out

These are the things that shape the price:

  • The product specified
  • Site requirements such as inductions and permits
  • Removal of failed or old sealant
  • How much there is to seal

Pricing colour-matched joints depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Any specification or named product
  • Any dates the work must fit around
  • What the building is and how it’s used
  • Where the site is, with the postcode

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

What we’re called out for in East Wickham

When frames are recoated or a space is rebranded, the old joints may no longer suit. Refurbishments and rebrands often bring a new colour scheme, and the joints need to match.

Any of the following is a good reason to get the joints checked over:

  • Standard-colour sealant spoiling a high-end finish
  • Smeared sealant on stone or joinery
  • Marked sealant in hotel bathrooms
  • A run of joints in mismatched shades

If you run an office at a site such as Gateway Business Centre, which lies north of East Wickham, the sealant at reception desks, tea points and frames ages with each fit-out.

Before you book anyone

  • The named product and why it was chosen
  • How long is the guarantee, and what does it include?
  • How the existing material will be dealt with
  • Proof of insurance
