Coloured sealant for businesses in South Street

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

Surface by surface

Powder-coated and anodised frames

Metallic and anodised finishes are hard to match exactly with sealant. We’ll suggest the nearest standard colours for approval.

Brick and masonry

Brickwork joints normally look best in a colour close to the mortar or brick. We choose a suitable shade from the product’s range.

Coloured sealant in South Street, done properly

We can agree a short trial length before the full run. Cured sealant may look a shade different from the wet bead, and lighting changes it again, so seeing it in place helps. Tell us who needs to approve the colour and we will plan for it. If you are dealing with joints that need to match a new RAL frame colour and dirty, discoloured joints in public areas, we can put it right, on shop-fit joinery and counters, office fit-out finishes and natural stone and brick alike. Facilities teams, main contractors and managing agents in South Street tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Business units in the countryside around places like South Street are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

Every job we finish is backed by a 12-month workmanship guarantee, in South Street as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common problems we fix in South Street

Failed sealant still has to be dealt with, whatever its colour: splits, adhesion loss and hardening all happen. We cut out and reseal in the agreed colour.

Things that normally lead to an enquiry:

  • Joints that need to match a new RAL frame colour
  • Old sealant that has yellowed, darkened or faded
  • A bead that fights the cladding or frame colour
  • A run of joints in mismatched shades

A hotel such as Cave Hotel and Golf Resort, 1 mile to the north of South Street, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Questions to ask before you appoint anyone

What South Street’s businesses ask us to seal

At about 47 miles from central London, South Street is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. If you have premises across the region, one contractor can cover them all. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Offices and shops close to stations such as Selling station, under half a mile south-west of South Street, tend to be busy all day, so sealant work is planned around opening hours.

South Street is about 3 miles south-east of Preston, in Kent. Any commercial site in South Street is covered. South Street is one of 931 places we cover in Kent. Sites around London have their own page, roughly 47 miles from South Street.

What sets the cost

The price varies from site to site. It mainly depends on:

  • The total length or number of joints
  • Travel to remote or island sites
  • Any access equipment needed
  • Which sealant the job calls for

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Sending details for a quote

A good diagnosis starts with the right details. Tell us:

  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • Your programme or deadline
  • Any specification or named product

For a fixed quote, speak to us on 01277 525 020 or send details through our quote form. You can also send details through our quote form.

Commercial clients in South Street

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

South Street: questions and answers

Which documents can you supply for work in South Street?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is South Street too small for you to travel to?

No. Places such as South Street are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

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

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

Can wet areas have colour-matched sealant?

Yes, in many cases. Hotel bathrooms, washrooms and kitchens often use coloured sanitary silicone to suit tiles or stone in commercial interiors.

Can we specify the colour by RAL number?

Yes. Give us the RAL reference and we will check it against the product’s range. We’ll tell you which colour is closest before work starts.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like South Street are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance
