Facade sealing across Tarbert

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

Facade sealing in Tarbert

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. The enquiries we see most involve failed seals around shopfront and entrance frames and staining on stone next to old sealant, on coping and flashing joints, window and door perimeters and stone and brick facade joints. Most enquiries from Tarbert 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.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Tarbert that means watching the forecast. We build some give into the plan and agree it with the site manager.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Building owners, agents and FMs in Tarbert

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

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.

Different surfaces, different methods

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

Sites and facades in and around Tarbert

The sea is no more than about 1 mile from Tarbert. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Tarbert is on Scotland’s wetter western side. Outside mastic is booked around the forecast, and internal sealing fills the gaps.

Hotels like Hotel Hebrides, under half a mile south-east of Tarbert, rarely close for long, so refurbishment mastic is phased floor by floor. For contractors building in or near Tarbert, we seal to the drawings, the specification and the programme.

Tarbert (Gaelic: An Tairbeart) is in Na h-Eileanan Siar. We cover commercial sites throughout Tarbert, whether it’s a single job or part of a planned programme. 87 places across Na h-Eileanan Siar fall within our area, Tarbert among them.

We cover the HS3 postcode districts for facade joints. Among the streets we cover are Main Street, Scott Road and Sraid Mhiccuinn, and sites on any of them can send details for a fixed quote. Being close to the A868, Tarbert is easy to get to with materials and equipment. Just outside Tarbert, we also work in Direcleit (1 mile south), Miabhaig (2 miles south), Drinisiadar (3 miles south), Plocrapool (4 miles south-east) and Greosabhagh (4 miles south). Tarbert is one of the busier places in Na h-Eileanan Siar, and its commercial and public buildings are all within our area. Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you call the office on 01277 525 020 or use the quote form.

Tarbert: questions and answers

Can being near the sea in Tarbert affect the sealant we need?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Will you fit the mastic around our build programme in Tarbert?

Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

How many days will you need on site?

It depends on the scope, but the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we will set out a timescale with the quote.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Can you handle several sites?

Yes. Several buildings can share a single quote, with one point of contact.

Maintenance after handover

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

  • Insist on a full cut-out when joints are renewed
  • Brief window cleaners about newly sealed joints
  • Investigate damp beside windows promptly
  • Clear debris that holds water against joints

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For work around Tarbert, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Send any specification or drawings in advance
  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Related advice

Should maintenance staff do it?

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

For most general trades, sealant is a sideline. 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.

When it isn’t the sealant

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

  • Joints too narrow for the movement they take, which need redesign
  • Cracked or spalling substrates that need repair before sealing
  • Work on the window or framing system itself

If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think before you book.
