Commercial mastic work in An t-Ob

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. If you’re dealing with layers of sealant, all of them failing and untidy joints in a reception, shop floor or lobby, we can put it right, whatever the surface. Looking for mastic applicators who cover An t-Ob? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

The most common commercial job in An t-Ob is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

Around smaller places such as An t-Ob, the commercial buildings tend to be hospitality, local shops, schools, health centres and converted rural buildings. Each has kitchens, washrooms and frames that depend on sound joints.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Owners, agents and contractors

We work for building owners and managing agents on everything from one building to a spread of sites around An t-Ob. Several sites can go on one quote, so there’s one set of paperwork to deal with.

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, and each stage is agreed with your contact.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • The product specified
  • Induction, permit and paperwork requirements
  • The size and state of each joint
  • Travel to remote or island sites

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • Specification clauses that apply

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Have extract fans checked so wet areas dry out
  • Look at the sealant around anything that has been moved or replaced
  • Keep a record of which joints were resealed and when
  • Respect the cure time before reopening an area

In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, and mould follows damp. It’s worth having fans checked while the sealant is fresh.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

Working on commercial sites near An t-Ob

An t-Ob is within about 1 mile of the coast. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Sea-facing elevations are normally where failed joints show first. Island jobs, An t-Ob among them, are planned around the ferry and the forecast. Photos and a full list before we travel, with any colour references, mean everything comes on the first crossing.

For premises around An t-Ob where the joint is seen, colour options for the product are confirmed with the quote. A lasting commercial joint around An t-Ob begins with the old bead fully out and the faces clean and dry.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Structural cracks or movement the joints weren’t designed for

If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in An t-Ob

Questions we’re asked in An t-Ob

Can you match sealant colours for premises in An t-Ob?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we will confirm what’s available for the product.

Will you travel to An t-Ob on the island?

Yes, An t-Ob is within the area we cover. We cover the whole of Scotland. We group island work where we can and plan around the crossings.

How is commercial sealant work priced?

Photos, drawings or a schedule of the joints are usually enough to start through our quote form. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.

How many days will you need on site?

It depends on the scope, but the work normally takes a few hours for one area, or a planned series of visits across a bigger building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you work for facilities managers and managing agents?

Yes. FMs, managing agents and landlords are among our regular clients as well as contractors. Tell us how you issue work and we’ll fit in.

Does commercial sealant work come with a guarantee?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a few hours for one area, or a planned series of visits across a bigger building. Travel to smaller Scottish places like An t-Ob is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. We start with the evidence: photos, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

What we need from you

  • Make sure the joints can be reached
  • Let building users know which areas are affected
  • Send your site hours and access windows

Advice

What happens if it’s left?

Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise. Exposed buildings in Scotland take a lot of weather, and for a smaller place like An t-Ob, a repair visit takes planning, so it’s better to act early.

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