Facade sealing across Rothesay

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

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 usually takes a day or two for a few elevations, and longer where access has to be moved around the building. For work around Rothesay, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot

Facade sealing for commercial buildings in Rothesay

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. Most enquiries involve unsightly perimeter sealant on a visible elevation and air leaks through failed facade joints, across cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure. Facilities teams, main contractors and managing agents in Rothesay tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

External sealing around Rothesay depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When something else is needed

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

  • Damaged frames that need replacing
  • Damp caused by condensation inside the building
  • Work on the window or framing system itself

Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.

Surfaces we seal

  • Stone and brick facade joints
  • Shopfront frames
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Window and door perimeters
  • Cladding panel joints

Facades, frames and programmes in Rothesay

The sea is no more than about 1 mile from Rothesay. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Projects in Rothesay follow Scotland’s building regulations, with the local authority acting as verifier. The mastic follows the specification that goes with the warrant.

Extensions at sites like Victoria Hospital (to the south of Rothesay) usually sit beside working departments, and the mastic follows strict access rules. For contractors at a school such as Rothesay Academy, sealing has to be finished before term starts.

Rothesay is about 13 miles south-west of Greenock, in Argyll and Bute. We send applicators to Rothesay for facade joints, handled exactly as we handle every other area. Our Argyll and Bute coverage takes in 124 places, from busy centres to rural villages. Glasgow is covered too, some 30 miles away.

We take on facade joints across the PA20 postcode area. Streets here include High Street, Ladeside Place and Ladeside Street. Access to Rothesay is via the A844 and B878 among other routes. Nearby places we also cover include Craigmore (1 mile east), Ardbeg (1 mile north), Port Bannatyne (2 miles north), Toward (4 miles north-east) and Innellan (5 miles north-east). Further afield, our area takes in Dunoon (10 miles north-east), An Tairbeart (14 miles west) and Sandbank (11 miles north-east). Rothesay is one of the busier places in Argyll and Bute, 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 give the site location in your enquiry.

How the quote is worked out

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

  • How accessible the joints are
  • The site’s rules and procedures
  • Joint width, depth and condition
  • The product specified

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

However big the job, the same details help:

  • Your programme or deadline
  • Any specification or named product
  • Asbestos survey details if the building is older
  • The site address and postcode

Your questions answered

Is Rothesay too small for you to travel to?

No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Bute Business Park, close to Rothesay?

Yes. Our area takes in Rothesay and its surroundings, with estates and business parks such as Bute Business Park included. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

Do you seal facades in winter?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings.

Can you work while the building is occupied?

Typically, yes. Phased work can be planned so areas stay in use.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is it fine to apply new sealant on top of old?

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

Signs you need facade sealing in Rothesay

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

Most enquiries start with one or more of the following:

  • Draughts around frames and panels
  • Old perimeter mastic that has dried out
  • Patch repairs that keep failing
  • Water coming in around window frames

Historic houses such as Ascog House (to the south-east of Rothesay) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Should maintenance staff do it?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Leave it or put it right?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Rothesay, a repair visit takes planning, so it’s better to act early.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
