Coloured sealant for St Paul's Cray sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Maintenance after handover

To get the most from the new sealant:

  • Avoid abrasive pads on coloured sealant
  • Check a trial length in real light
  • Put the colour reference on the finishes schedule
  • Reseal whole runs rather than patching single joints

Clean coloured joints with mild, non-abrasive products. Harsh chemicals and scouring can change how the colour looks over time.

Standardise the sealant colour on multi-site work. Consistency makes future work simpler.

Coloured sealant in St Paul's Cray

On a finished interior or a high-quality elevation, the sealant is part of the look. Our coloured sealant work blends joints into the surrounding materials, from powder-coated frames to stone and brick. Performance decides the product; the colour is chosen from that product’s range. We work on powder-coated and anodised frames, office fit-out finishes and hotel bathrooms and public areas, and what we’re called in for most is marked sealant in hotel bathrooms and failed coloured sealant that has split or peeled. Most enquiries from St Paul's Cray 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.

In London, most commercial sealant work happens in buildings that stay open: occupied offices, ground-floor retail under residential floors and busy shared entrances. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • How much there is to seal
  • Joint width, depth and condition
  • Site requirements such as inductions and permits
  • Travel to remote or island sites

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • When you need the work done
  • Anything awkward about access or site hours
  • The postcode of the building
  • What the building is and how it’s used

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email us.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

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, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in St Paul's Cray can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We confirm the product the joint needs before talking about colour.
  2. We compare your RAL reference or sample with the colours made for that sealant.
  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. The coloured sealant is applied and tooled with clean, masked edges.

What we need from you

  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings
  • Warn occupants and staff about the work

Different surfaces, different methods

Paintable sealants

Overpainting is most common on internal joints with little movement. If the joint needs a product that can’t be painted, we say so.

Cladding panels

Multi-coloured cladding needs a joint colour that works across it. Sometimes a mid-tone suits better than matching one panel and we can trial it first.

Coloured sealant around St Paul's Cray: what changes locally

At least three named trading, business or retail sites lie within about 3 miles of St Paul's Cray. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. A number of hotels sit less than 2 miles from St Paul's Cray. 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.

If you have premises on more than one site, say at Brook Industrial Estate and Nugent Retail Park, one contractor and one quote can cover both. In hotels such as TLK Apartments & Hotel, 0.5 miles to the south-east of St Paul's Cray, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. If you run a unit on an estate such as Brook Industrial Estate (less than half a mile south-east of St Paul's Cray), the trade counter, offices and staff facilities have joints to look after as well as the warehouse.

Questions about St Paul's Cray

Will you take on work at estates like Brook Industrial Estate, close to St Paul's Cray?

Yes. We cover St Paul's Cray and the area around it, including industrial estates, business parks and retail parks such as Brook Industrial Estate. Photos and a short description are enough for a first look.

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. 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

Can you work to a RAL reference?

Yes. We compare the RAL reference with the colours made for the specified sealant. You will see the nearest options before work starts.

Do you take on colour-matched sealant for shop fits and multi-site roll-outs?

Yes. Shop fits, hotels and office fit-outs are a regular part of our work. Our area takes in Greater London, the South East and Scotland, so one colour reference can carry across every site.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

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.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
