How we handle mastic sealing in Sgalpaigh

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you are dealing with water getting in round frames after rain and open joints in brickwork or panels, we can put it right, on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints alike. A single leaking joint is often how a building in Sgalpaigh first comes to us: we look at the rest while we’re there and tell you what we find.

In smaller Scottish places like Sgalpaigh, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic typically fails first.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Quoting for work in Sgalpaigh

We price every job individually. The main factors are:

  • Phasing around occupants
  • How accessible the joints are
  • Travel to remote or island sites
  • The site’s rules and procedures

A quote for mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Approximate linear metres or a joint schedule
  • Specification clauses that apply
  • Access details, including height
  • What the building is and how it’s used

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or send details through our quote form if you’d rather talk the job through.

FAQs: Sgalpaigh

Can you take on a job in Sgalpaigh, on the island?

Yes. Every Scottish council area is within our area, and that includes island locations such as Sgalpaigh. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Can you quote for mastic across several buildings in and around Sgalpaigh?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

Do you work for managing agents and housing associations?

Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.

Do you supply RAMS and insurance details?

Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Can you seal joints high up on a block?

We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

How long does a job like this take?

It depends on the scope, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.

What we’re called out for in Sgalpaigh

Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.

Clients usually get in touch after noticing one or more of the following:

  • Movement joints with sealant missing
  • Estate-wide sealant that is simply worn out
  • Draught complaints from residents or tenants
  • Damp patches beside frames

Around Sgalpaigh, a planned programme renews failed mastic across a building or estate in one go.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Their approach to joint depth and backing
  • Whether their applicators hold CSCS cards
  • Will failed sealant be removed rather than covered?

Choosing a commercial sealant contractor

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Where we can, we combine work around Sgalpaigh with other jobs nearby. Let us know if your dates have any give.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

What we need from you

  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand

Planned mastic for Sgalpaigh portfolios

Sgalpaigh is within about 2 miles of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Sgalpaigh is in the west of Scotland, the wetter side of the country. Exposed elevations on blocks take a soaking and their mastic shows it. External work is booked for dry spells, with a little give in the dates.

Near Sgalpaigh, we review each elevation first so the quote covers what actually needs doing.

Sgalpaigh (Gaelic: Scalpay) is in Na h-Eileanan Siar. Sgalpaigh sits inside our coverage and the rest of Na h-Eileanan Siar, with the same fixed quotes and 12-month guarantee as everywhere else. Our Na h-Eileanan Siar coverage takes in 87 places, large and small.

We cover the HS4 postcode districts. Sites close to Sgalpaigh are covered too, including Plocrapool (3 miles south-west), Drinisiadar (3 miles west), Scadabhagh (3 miles south-west), Miabhaig (4 miles west) and Greosabhagh (4 miles south-west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Masonry that has broken away beside the joint
  • Misted or failed double-glazed units
  • Failed window or door frames, which need a window contractor

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Where we work in Sgalpaigh

  • External wall and movement joints

Owners, agents and contractors
