Construction mastic for Branahuie sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle construction mastic in Branahuie

Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Branahuie, send drawings through our quote form, or phone or email us to talk it through. If you are dealing with failed sealant in an existing building being refurbished and early adhesion failures on new external joints, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Branahuie, that means joint design, primers and backing rod as standard.

External sealing around Branahuie depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Contractors’ notes for Branahuie

The sea is no more than about 1 mile from Branahuie. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Island jobs, Branahuie among them, are planned around the ferry and the forecast. With drawings and the programme in hand, the whole mastic package comes with us.

For a contractor working at a hospital such as Western Isles Hospital, 2.6 miles to the west of Branahuie, perimeter and facade sealing is planned around patients and deliveries.

Branahuie is about 2 miles east of Stornoway, in Na h-Eileanan Siar. Across the HS2 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 87 places across Na h-Eileanan Siar fall within our area, Branahuie among them.

Anyone looking for construction mastic in HS2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. We also cover Bràigh na h-Aoidhe (1 mile south-east), Sanndabhaig (1 mile west), Sandwick (1 mile west), Steinis (1 mile north-west) and Plasterfield (1 mile west). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Near you in Branahuie

Nearby you will also find Western Isles Hospital (2.6 miles west) and Lewis Loom Centre (2.6 miles west). Green spaces nearby include Loch Àirigh na Lic.

Signs you need construction mastic in Branahuie

Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.

What tends to prompt an enquiry:

  • Oversized or tapered gaps around new frames
  • Missed perimeter joints on a new elevation
  • Early adhesion failures on new external joints
  • Sanitary sealant damaged by following trades

When units on a site such as Parkend Industrial Estate, 1 mile south-west of Branahuie, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • What level of public liability insurance do they hold?
  • Their pre-qualification and accreditations
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Keep product details for future maintenance
  • Release areas for mastic once other trades have finished in them
  • Check frame gaps are within the sealant’s range before sealing
  • Stick to the specified sealant rather than a generic substitute

Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.

Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out and keeps handover on track.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Deciding which fire-stopping product a penetration needs
  • Glazing units that are cracked or misted
  • Frames fitted out of tolerance

If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think before you book.

What we seal

  • Brick and block movement joints
  • Window and door perimeters
  • Floor and skirting junctions
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Sanitary and kitchen joints

Why deal with it now?

Sealing over damaged or contaminated new joints might save a day, but it won’t last. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. We cut out and redo the joint properly. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why appoint us

  • Coloured sealants to suit the setting, where available
  • Colours confirmed for the specified product
  • 12 months’ guarantee on every job
  • Colours chosen to suit frames, cladding or finishes where possible

Branahuie: questions and answers

Does your area include sites such as Parkend Industrial Estate, near Branahuie?

Yes, sites like Parkend Industrial Estate are within our area, along with the rest of Branahuie. A few photos and the unit address let us price the work.

Would you work within a site like Western Isles Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you do fire-rated sealing on new builds?

We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we will tell you.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you use the sealant named in the specification?

We work to the specification and the manufacturer’s installation guidance. Primers, backing and joint depth follow what the manufacturer sets out.

Is the mastic package guaranteed?

The work is guaranteed for 12 months, covering how we sealed. Protecting sealed areas from following trades helps avoid damage.

Can you clear a mastic snag list before handover?

Yes, we can. Send the snag list or photos and we will price it.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Branahuie, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Warn occupants and staff about the work
  • Arrange parking or a loading space
  • Have the specification and drawings to hand

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email us with what you know.
