How we handle construction mastic in Sandwick

Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on cladding and panel joints, brick and block movement joints and window and door perimeters, and the failures we’re asked to look at most are failed sealant in an existing building being refurbished and external joints sealed in damp or cold conditions that are now failing. One point of contact handles commercial sealant work in Sandwick from the first photographs to the final walk-round, for single jobs and planned programmes alike.

In smaller places such as Sandwick, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Tell us who will meet us and how to get in at your building near Sandwick. That goes into the plan alongside the quote.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Flag any permit to work we’ll need
  • Share the asbestos register for older buildings

Construction mastic in Sandwick: the local picture

The sea is no more than about 1 mile from Sandwick. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Sandwick is on Scotland’s drier eastern side. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External mastic is planned with the site manager for workable conditions.

Sites around Sandwick get mastic sealed to the drawings and the programme, nothing improvised.

Sandwick is about 14 miles north of Lerwick, in the Shetland Islands. Sandwick sits inside our coverage and the rest of the Shetland Islands, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Sandwick is one of 63 places we cover in the Shetland Islands.

We take on mastic packages across the ZE2 postcode area, for business premises of every kind. We cover commercial and managed buildings on Rocky Road, Saeter and Harlsdale. If your building is just outside Sandwick, we cover Clate (1 mile south), Symbister (1 mile north-east), Hamister (1 mile north), Huxter (1 mile east) and Tripwell (2 miles north-east). Nearby towns on our patch include Lerwick (14 miles south), Sound (14 miles south) and Brae (12 miles west). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you phone 01277 525 020 or email us.

Different surfaces, different methods

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services. Record requirements are agreed with the quote.

Kitchens and utility areas

Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.

Signs you need construction mastic in Sandwick

Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.

Look out for the following:

  • Snag items on joints that need redoing before handover
  • Existing joints on a refurb that need cutting out and resealing
  • A mastic package split between trades with no clear owner
  • Frame perimeters left unsealed or poorly sealed

A facade joint near Sandwick lasts when width, depth and backing are right, not just the finish.

Questions to ask before you book

  • How joint depth will be controlled
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?
  • How long is the guarantee, and what does it include?

Questions to ask before you appoint anyone

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Common questions from Sandwick clients

Will you travel to Sandwick on the island?

Yes. Our area covers all of Scotland, cities, towns and islands alike, and that includes island locations such as Sandwick. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Can the mastic package for our job in Sandwick follow the site programme?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Why deal with it now?

When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Around smaller places like Sandwick, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
