Aftercare for building managers

A few simple habits keep the new joints working:

  • Keep finished joints away from paint, plaster and scrapers
  • Note which sealant went where at handover
  • Check frame gaps are within the sealant’s range before sealing
  • Ask cleaners to use soft cloths around fresh sealant

Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.

Construction mastic for commercial buildings in Port Appin

On a new build, the mastic package is one of the last trades through each area. Mastic Doctor takes on mastic packages for main contractors and developers on schemes in Port Appin, sealing plot by plot or floor by floor as areas are released. Site teams most often ask us about inconsistent sealant finishes from plot to plot and sanitary sealant damaged by following trades, across sanitary and kitchen joints, internal decorators’ caulk and brick and block movement joints. Most enquiries from Port Appin start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

External sealing around Port Appin 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.

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Where we can, we combine work around Port Appin with other jobs nearby. Let us know if your dates have any give.

  1. First we look at the scope on site or from drawings.
  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.

Getting the site ready

  • Let us know about inductions and permits
  • Make sure the joints can be reached
  • Explain the parking and delivery arrangements

Quotes

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email us.

What we are called out for in Port Appin

Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.

Most enquiries start with something like this:

  • External joints sealed in damp or cold conditions that are now failing
  • Failed sealant in an existing building being refurbished
  • Cracks opening in caulked internal joints
  • Sealant knocked or painted over by other trades

For contractors building in or near Port Appin, we seal to the drawings, the specification and the programme.

What to look for in a quote

  • Their plan for phasing and protecting the area
  • Whether their applicators hold CSCS cards
  • How they handle RAMS and site documents
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

Mastic packages on Port Appin sites

The sea is no more than about 1 mile from Port Appin. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Scotland has its own building regulations, and in Port Appin warrants come from the local authority verifier. Our job is to seal to that specification.

Around Port Appin, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

Port Appin: questions and answers

Is a smaller place like Port Appin outside your area?

No. Small places get the same service as large ones. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.

Does a coastal location like Port Appin 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.

What accreditations do you hold?

We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

What the job involves on each surface

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product, food-safe where food contact is possible.

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Glazing units that are cracked or misted
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Oversized gaps that need packing or adjustment by others

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Surfaces we seal

  • Internal decorators’ caulk
  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Cladding and panel joints
