Facade sealing for Carndu sites

About our facade sealing in Carndu

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. Most enquiries involve old perimeter mastic that has dried out and cold air coming in at window perimeters, on shopfront frames, cladding panel joints and coping and flashing joints. A specialist sealant contractor works differently from a general builder: on jobs in Carndu, preparation and product choice get the time they need.

Sites near smaller places like Carndu can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photos and the programme so everything needed arrives on the first day.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Mastic packages on Carndu sites

Carndu sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Scotland has its own building regulations, and in Carndu warrants come from the local authority verifier. The mastic package follows the approved specification.

When units on a site such as Ardelve Industrial Estate, 1 mile to the south-west of Carndu, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hotel extensions and refits, at places such as Dornie Hotel, which lies south-west of Carndu, normally run between busy periods, so the sealing is squeezed into short windows.

Carndu is in Highland. Anywhere in IV40, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Carndu is one of 256 places we cover in Highland for facade joints.

We take on facade joints across the IV40 postcode area, whatever the building. Buildings on Helen Street, Princes Street and William Street are within our area. If your building is just outside Carndu, we cover Bundalloch (1 mile north-east), Dornie (1 mile south-west), Auchtertyre (3 miles west), Inverinate (5 miles south-east) and Reraig (5 miles west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Landmarks near Carndu

The nearest railway station is Stromeferry station, roughly 4.8 miles north-west. A little further out are Eilean Donan Castle (1.1 miles south-west). The countryside around Carndu includes Loch Anna.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Render or concrete edges that have broken away
  • Work on the window or framing system itself
  • Joints too narrow for the movement they take, which need redesign

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

Surfaces we seal

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

FAQs: Carndu

Our building in Carndu is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Can you work at a site such as Ardelve Industrial Estate, by Carndu?

Yes, sites like Ardelve Industrial Estate are within our area, along with the rest of Carndu. Send details of the unit and the work through our quote form for a quick quote.

Do you replace failed glazing units?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels on commercial buildings.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Work for main contractors and building owners

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.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Surface by surface

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.

Why deal with it now?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Renewing every failing joint on one visit is the sensible approach for a place like Carndu. Photos of each area help us quote the whole job.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. Where we can, we combine work around Carndu with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
