Questions about Portskerra

Is a smaller place like Portskerra outside your area?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.

Do you offer colour-matched sealant for buildings in Portskerra?

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.

Can staff carry on working while you’re here?

Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How many days will you need on site?

It depends on the scope, but the work usually takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

How do you deal with asbestos in old sealant?

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. We don’t remove asbestos-containing materials.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Coloured sealant in Portskerra

A coloured bead has to perform like any other sealant. Faces are prepared, depth is fixed with rod and the bead is tooled onto two sides only, exactly as for a standard colour. Clean masking and steady tooling give the sharp lines colour work needs. Most enquiries involve standard-colour sealant spoiling a high-end finish and coloured joints that have cracked with movement, on natural stone and brick, cladding panels and shop-fit joinery and counters. For commercial sealant work in Portskerra, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Scottish weather decides a lot about outside work in a place like Portskerra: sealant needs a dry joint and the right temperature, so external work has a weather window built in. Internal joints can be done whatever the day brings.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • A colour that never alters with age
  • Colour variation across natural stone or brick that no single shade can match
  • Repairing damaged frames or cladding

If you’re not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer.

Where we work in Portskerra

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

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Approve a sample bead on high-profile areas
  • Clean coloured joints with mild products
  • Reseal whole runs rather than patching single joints
  • Keep the area clear while the sealant cures

Expect some change in appearance over the years. Some fading is part of normal ageing outdoors, and a reseal brings it back.

Approve a sample where colour really matters. Seeing the cured colour in place avoids surprises.

For managing agents and facilities managers

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Portskerra can form part of a wider programme across Highland.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Tell us who will meet us and how to get in at your building near Portskerra. We’ll confirm the plan with the fixed quote.

  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. The coloured sealant is applied and tooled with clean, masked edges.

Getting the site ready

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows

Surface by surface

Shop-fit and joinery finishes

Shop fits bring laminate, timber, metal and stone together, each with its own colour. We choose sealant colours that suit each junction as agreed with the designer.

Office fit-outs

In offices, sealant appears at partitions, tea points, washrooms and reception desks. Colour-matched joints keep the finish consistent across floors.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Sealant on show in Portskerra’s commercial buildings

The sea is no more than about 1 mile from Portskerra. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. Where a frontage needs a particular colour, the product still has to suit that exposure. Portskerra is in the east of Scotland, which is drier than the west. Frost and condensation on winter mornings can still hold up external sealing. In winter, outside joints are timed for when surfaces are dry and within the product’s range

A lasting commercial joint around Portskerra begins with the old bead fully out and the faces clean and dry. For a hotel such as Melvich Hotel, which lies south of Portskerra, the colour of a joint at the bar or the bath matters to the look of the room.

Portskerra is about 15 miles west of Thurso, in Highland. Across the KW14 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 256 places in Highland.

Postcode districts covered here: KW14. Buildings on Bayview Avenue, Mackay Terrace and Shore Street are within our area. Close to Portskerra, our area also takes in Melvich (1 mile south-east), Strathy (3 miles west), Reay (5 miles east), Am Blàran Odhar (11 miles west) and Forss (11 miles east). For island and remote sites, travel and materials need planning ahead.
