Facade sealing around Kilmartin: what changes locally

Kilmartin lies within about 3 miles of the sea. 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. Kilmartin is in the west of Scotland, the wetter side of the country. External mastic dates are agreed with the site manager, with internal sealant kept ready for wet days.

On any site in or around Kilmartin, the mastic follows the specification and the programme. Work at a hotel such as Kilmartin Hotel (to the south of Kilmartin) tends to be programmed around bookings, mastic included.

Kilmartin is about 30 miles north-west of Greenock, in Argyll and Bute. Kilmartin sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 124 places in Argyll and Bute. Our Glasgow page has more on work in that area.

Facade sealing in Kilmartin, done properly

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have perimeter sealant that has split or peeled away and draughts around frames and panels, we can put it right, on stone and brick facade joints, perimeter joints where frames meet the structure and coping and flashing joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Kilmartin is the same: the right product in a properly prepared joint.

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

Our 12-month guarantee is about workmanship, not 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.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Where we can, we combine work around Kilmartin with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  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. 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.

Before we start on site

  • Let us know about inductions and permits
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Don’t wait for a second leak before calling
  • Confirm the survey covers external sealants in older buildings
  • Clear debris that holds water against joints
  • 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.

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

Different surfaces, different methods

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Specialist high-level access methods
  • Water getting in through cracked render or porous masonry
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Where we work in Kilmartin

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

Cost factors for facade joints

To price the job, we consider:

  • Any access equipment needed
  • Site requirements such as inductions and permits
  • The product specified
  • The total length or number of joints

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • What the building is and how it’s used
  • Access details, including height
  • Your programme or deadline
  • The product your specification calls for

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or use the quote form to discuss it first.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Your questions answered

Can you keep pace with our programme in Kilmartin?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like Kilmartin outside your area?

No. Places such as Kilmartin are covered as much as the big towns. We cover the whole of Scotland. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.
