Coloured sealant in Steel Cross

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Different surfaces, different methods

Office fit-outs

Office joinery and frames typically follow a colour scheme. We choose sealant colours to suit and agree them before work starts.

Paintable sealants

Some joints are better sealed with a paintable product and decorated. That only works where the joint and specification allow it, as paint can crack on a moving joint.

Coloured sealant for commercial buildings in Steel Cross

Where colour is critical, a sample bead in a discreet spot settles the question. Cured sealant may look a shade different from the wet bead, and lighting changes it again. Let us know who signs off colour, and we’ll fit the sample into the programme. We work on natural stone and brick, cladding panels and shop-fit joinery and counters, and the failures we are asked to look at most are patch repairs in several different colours and fit-outs with a sealant colour in the specification. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Steel Cross is the same: the right product in a properly prepared joint.

Rural business units near smaller places such as Steel Cross are frequently converted agricultural buildings. 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions we’re asked in Steel Cross

Does your area include sites such as Crowborough Business Park, near Steel Cross?

Yes. Our area takes in Steel Cross and its surroundings, with estates and business parks such as Crowborough Business Park included. Photos and a short description are enough for a first look.

Can the sealant on our Steel Cross premises match the finishes?

Yes, we can typically get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Why act early in Steel Cross

A standard colour is quicker to source, though not always right. Where joints are on show, choosing a better colour is usually worth it at handover. Halls, stores and units around places like Steel Cross may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The price depends on the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

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, which is what makes a joint last.

Coloured sealant in Steel Cross: the local picture

Steel Cross lies roughly 32 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. Multi-site occupiers here often want one sealant contractor across all their buildings. Steel Cross has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.

Occupiers with premises at both Crowborough Business Park and Lexden Lodge Industrial Estate could have the sealant at each handled under one quote. Offices at parks like Crowborough Business Park (to the west of Steel Cross) have receptions, kitchens and glazed partitions where a tidy joint matters. For premises near Crowborough station, 1.2 miles south of Steel Cross, footfall is part of the plan: work is phased so shops and offices keep trading.

Steel Cross is about 1 mile north-east of Crowborough, in East Sussex. We cover commercial sites throughout Steel Cross, whether it’s a single job or part of a planned programme.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

We work for building owners and managing agents on everything from one building to a spread of sites around Steel Cross. One quote can cover more than one site, which keeps the paperwork simple.

On site: what to expect

Working in a building that stays open takes some planning. 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. If others near Steel Cross need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. The sealant type is chosen for the joint first, then the colour.
  2. We compare your RAL reference or sample with the colours made for that sealant.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  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.

Getting the site ready
