Coloured sealant across Longcroft

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

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • A colour that never alters with age
  • A guaranteed perfect match to every finish
  • Repairing damaged frames or cladding

If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Where we work in Longcroft

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

Coloured sealant in Longcroft, done properly

Stone, brick and cladding each bring their own colour challenge: sandstone, granite, brick and stained timber rarely have one flat colour. The aim is a sealant colour that sits comfortably against the whole surface. Most enquiries involve fit-outs with a sealant colour in the specification and sealant that no longer suits recoated frames, across hotel bathrooms and public areas, shop-fit joinery and counters and cladding panels. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Longcroft is the same: the right product in a properly prepared joint.

For work in and around Longcroft, we’d rather do everything on one trip: send photographs and a complete list so the right products and colours come on the day. If neighbouring businesses have work too, the visits can be grouped.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to call us in Longcroft

Sometimes the wrong colour went in at the start. The joint may work perfectly but look out of place.

If one of these sounds familiar, it’s time for a closer look:

  • Discoloured joints on a visible elevation
  • Shop fits that need consistent sealant colours across sites
  • Dirty, discoloured joints in public areas
  • Smeared sealant on stone or joinery

A unit on an estate like Chattan Industrial Estate, 2.1 miles to the east of Longcroft, typically has an office front, a trade counter and staff facilities with joints of their own.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?

Choosing a commercial sealant contractor

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Travel to smaller Scottish places like Longcroft is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. Tell us your site hours and access windows and we’ll plan around them.
  4. Joints are prepared, primed where specified and backed.
  5. We seal in the approved colour and tool it smooth.

What we need from you

  • Tell us which areas need to stay in use
  • Flag any permit to work we will need
  • Explain the parking and delivery arrangements

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Related advice

Different surfaces, different methods

Natural stone

Sandstone, limestone and granite each have distinct tones. Colour is agreed on site where possible.

Paintable sealants

Overpainting is most common on internal joints with little movement. We’ll tell you if a joint needs a non-paintable product.

What affects the price in Longcroft

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • The product specified
  • Removal of failed or old sealant
  • Travel to remote or island sites

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back
  • When you need the work done
  • Whether the building will be occupied during the work

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email a schedule or drawings.

Your questions answered

Can you work at a site such as Chattan Industrial Estate, by Longcroft?

Yes, sites like Chattan Industrial Estate are within our area, along with the rest of Longcroft. A few photographs and the unit address let us price the work.

Is a smaller place like Longcroft outside your area?

No. Places such as Longcroft are covered as much as the big towns. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.

Are you fully insured?

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

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Does coloured sealant change colour outdoors?

It can, to a degree. How much depends on the product, the colour and the exposure.

Can you work to a RAL reference?

Yes. RAL references are a common way to specify sealant colour. We will confirm the colours available for the specified product and agree the nearest option.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Leave it or put it right?

It’s far cheaper to approve a sample than to strip and redo a full run. A short trial bead costs very little against redoing a whole elevation. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Longcroft before they leak.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Why us?

  • One contact handling all your sites
  • Work carried out by CSCS-carded applicators
  • A range of standard colours, depending on the product
  • 12-month guarantee on workmanship
