Facades, frames and programmes in Diuranais

The sea is no more than about 1 mile from Diuranais. 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. The west of Scotland, where Diuranais is, gets more rain than the east. Outside mastic is booked around the forecast, and internal sealing fills the gaps.

On any site in or around Diuranais, the mastic follows the specification and the programme.

Facade sealing in Diuranais

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces. Most enquiries involve weathered facade joints that have lost their grip and unsightly perimeter sealant on a visible elevation, on coping and flashing joints, cladding panel joints and window and door perimeters. Searching for sealant specialists in Diuranais? We’ve been sealing commercial buildings since 2005.

For a site around Diuranais, we plan the mastic in as few trips as the programme allows. Send drawings, photographs and the programme so everything needed arrives on the first day.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Why act early in Diuranais

Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Around smaller places like Diuranais, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why clients in Diuranais choose us

  • Failed material removed, not covered up
  • One phone line for London, the South East and Scotland

FAQs: Diuranais

Is a smaller place like Diuranais outside your area?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

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

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.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can one quote cover more than one building?

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

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

What affects the price in Diuranais

The price varies from site to site. Expect it to depend on:

  • Phasing around occupants
  • Travel to remote or island sites
  • The product specified
  • Whether old sealant has to be cut out first

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.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • The postcode of the building
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email the details over if you’d rather talk the job through.

Do you need facade sealing in Diuranais?

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

Typical triggers for a call:

  • Gaps between rainscreen or cladding panels
  • Staining on stone next to old sealant
  • Air leaks through failed facade joints
  • Perimeter joints where frames meet the structure

Work at a hotel such as Smoo Cave Hotel, 1.2 miles east of Diuranais, tends to be programmed around bookings, mastic included.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • How they’ll work around occupants
  • Will RAMS and insurance details be available?
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

Our process

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Travel to smaller Scottish places like Diuranais 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 look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Point out any areas we must not close
  • Make sure the joints can be reached

Advice

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Work on the window or framing system itself
  • Water getting in through cracked render or porous masonry
  • Cracked or spalling substrates that need repair before sealing

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