How the job changes 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, not the framing or glazing itself.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.

About our facade sealing in Caol

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have weathered facade joints that have lost their grip and water coming in around window frames, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Caol, preparation and product choice get the time they need.

For a site around Caol, 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.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Combine resealing with other works that need access
  • Keep pressure washers away from fresh sealant
  • Never let anyone seal over old sealant
  • Ask about asbestos in pre-2000 mastic

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

What affects the price in Caol

Quotes vary with the job. Expect it to depend on:

  • Distance, for remote addresses
  • Induction, permit and paperwork requirements
  • How much existing material needs removing
  • Working within restricted access windows

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Whether the building will be occupied during the work
  • When you need the work done
  • A wide shot and a close-up of the area
  • The postcode of the building

Facades, frames and programmes in Caol

The sea is no more than about 2 miles from Caol. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Projects in Caol follow Scotland’s building regulations, with the local authority acting as verifier. Our job is to seal to that specification.

When units on a site such as Blar Mhor Industrial Estate (to the east of Caol) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hospital estates such as Belford Hospital, 1.3 miles south of Caol, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. For a contractor at a hotel such as Ben Nevis Hotel and Leisure Club, 0.9 miles south-east of Caol, the mastic often has to be finished before a reopening date.

Caol is in Highland. Businesses, contractors and managing agents in Caol use us for work on facade joints. Our Highland coverage takes in 256 places. Our Glasgow page has more on work in that area (75 miles or so).

We take on facade joints across the PH33 postcode area, whatever the building. We cover commercial and managed buildings on Glen Nevis Road, Camesky Road and Macquarrie Court. Nearby places we also cover include Taobh Lochaidh (1 mile east), Banbhaidh (1 mile north), Inverlochy (1 mile south), Corpach (1 mile north-west) and Fort William (2 miles south). 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 Caol

Locally, jobs take us to sites close to Black Parks and Lochaber High School and the streets around them. Caol has its own railway station: Banavie station. Other landmarks nearby include Treasures Of The Earth (1.1 miles west) and Belford Hospital (1.3 miles south).

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Caol is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance

Your questions answered

Can you work at a site such as Blar Mhor Industrial Estate, by Caol?

Yes. Estates, retail parks and business parks around Caol, Blar Mhor Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

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

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can speak to us on 01277 525 020 or email the details over to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

General trades versus a specialist

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

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Damaged frames that need replacing
  • Movement beyond what any sealant can handle
  • Water getting in through cracked render or porous masonry

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

Surfaces we seal

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