Facade sealing for commercial buildings in Stromness

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. The enquiries we see most involve previous reseals run over old sealant and failed seals around shopfront and entrance frames, on stone and brick facade joints, window and door perimeters and shopfront frames. Most enquiries from Stromness 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.

Sites near smaller places like Stromness can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Mastic packages on Stromness sites

Stromness sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Stromness has a number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Projects at schools like stromness primary school work to term dates, so mastic is programmed tightly. Hotel extensions and refits, at places such as Royal Hotel (less than half a mile east of Stromness), typically run between busy periods, so the sealing is squeezed into short windows. University estates such as Heriot-Watt University - Orkney Campus, under half a mile north of Stromness, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Stromness is about 12 miles west of Kirkwall, in the Orkney Islands. Commercial clients in Stromness can call on us for facade joints. Stromness is one of 51 places in the Orkney Islands on our list for facade joints.

We cover the KW16 postcode districts. Buildings on Franklin Road, Manse Lane and Springfield Crescent are within our area. With the A965 nearby, Stromness is straightforward for us to reach. If your building is just outside Stromness, we cover Cairston (1 mile north-east), Clouston (3 miles north-east), Stenness (4 miles north-east), Hoy (4 miles south) and Wasbister (4 miles north-east). Among the larger centres in the Orkney Islands is Stromness, and its commercial and public buildings are all within our area. For island and remote sites, we plan travel and materials carefully, so the full address helps from the start.

FAQs: Stromness

Will you travel to Stromness on the island?

Yes. We work across every Scottish council area, and that includes island locations such as Stromness. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

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

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What type of sealant goes on window perimeters?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

Will you come and look before quoting?

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

Different surfaces, different methods

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building near Stromness, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Advice

What sets the cost

These are the things that shape the price:

  • Travel to remote or island sites
  • The size and state of each joint
  • Quantities, in metres or numbers
  • Phasing around occupants

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What to include in your enquiry

We can often quote from photographs and a few details. Please tell us:

  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Whether an asbestos survey exists
  • What the building is and how it’s used

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or send photos by email.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Check the asbestos register before old mastic is disturbed
  • Combine resealing with other works that need access
  • Walk the elevations once or twice a year
  • Brief window cleaners about newly sealed joints

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.

Leave it or put it right?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Stromness before they leak.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
