Mastic sealing in Eòlaigearraidh

For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve draught complaints from residents or tenants and a mix of products and colours from past repairs, across shopfronts below residential blocks, window and door perimeters on blocks and communal kitchens and washrooms. Most enquiries from Eòlaigearraidh start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Common questions from Eòlaigearraidh clients

Is Eòlaigearraidh inside the area you cover, given it’s on an island?

Yes, Eòlaigearraidh is within the area we cover. We cover the whole of Scotland. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Does a coastal location like Eòlaigearraidh affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you work with property factors and landlords?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

Which sealant will you use?

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.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Should maintenance staff do it?

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.

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

Signs you need mastic sealing in Eòlaigearraidh

Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.

Typical triggers for a call:

  • Occupiers reporting cold air round windows
  • Worn sealant at communal door frames
  • Damp patches beside frames
  • Brittle perimeter mastic across a building

For a building around Eòlaigearraidh, a look at every elevation first shows which joints need renewing now and which can wait.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will failed sealant be removed rather than covered?
  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?

How to choose a sealant contractor

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Water coming in from the roof or rainwater goods
  • Masonry that has broken away beside the joint
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • Communal entrances and stairwells
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Shopfronts below residential blocks

How the job changes by surface

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.

External movement joints

Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.

Frames, entrances and external joints in Eòlaigearraidh

The sea is no more than about 1 mile from Eòlaigearraidh. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. Eòlaigearraidh is in the west of Scotland, the wetter side of the country. The most exposed elevations need checking most often. We plan block programmes with the forecast in mind.

Owners near Eòlaigearraidh can renew frame and external mastic block by block on one programme.
