Mastic sealing in Na h-Eileanan Siar: how it works

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms, and what we’re called in for most is draughts at frames across a block and cracked, hardened mastic round windows on a block.

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Blocks and managed buildings across Na h-Eileanan Siar

Across Na h-Eileanan Siar, from Stornoway, Tarbert and Plasterfield outwards, managing agents, landlords and housing associations look after blocks, mixed-use buildings and estates. Mastic around frames, doors and on external joints wears out in time, and block-wide programmes deal with it in one go.

The west of Scotland is wetter than the east, but external sealing anywhere in Scotland needs a dry joint and the right temperature, with a little give in the programme for wet or frosty days. In the parts of Na h-Eileanan Siar near the sea, the elevations facing the weather are where sealant gives up first.

Stornoway: Owners near Stornoway can renew frame and external mastic block by block on one programme. If you own or manage units on a site such as Gleann Seileach Business Park, 0.8 miles to the north-west of Stornoway, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

What happens if it’s left?

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • Their public liability cover
  • Their pre-qualification and accreditations

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Check the asbestos register before any old mastic is disturbed
  • Track which buildings were done and when
  • Plan resealing building by building rather than complaint by complaint
  • Reduce knocks to communal area joints

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

Quoting for work in Na h-Eileanan Siar

Before we quote, we look at:

  • Working within restricted access windows
  • Travel to remote or island sites
  • Which sealant the job calls for
  • How much there is to seal

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Your programme or deadline

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email us.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Substrate edges that need repairing first
  • Leaks from above rather than through a joint
  • Leaks through the frame itself rather than the perimeter

FAQs: Na h-Eileanan Siar

Can you send RAMS and CSCS details before starting?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

How do you handle work on occupied blocks?

The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you take on resealing for a block portfolio?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

How do we ask for a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
