How we handle facade sealing in Balloch

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. The enquiries we see most involve weathered facade joints that have lost their grip and gaps between rainscreen or cladding panels, on coping and flashing joints, perimeter joints where frames meet the structure and shopfront frames. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Balloch it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site around Balloch, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email us and we’ll arrange a return visit.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. Tell us who will meet us and how to get in at your building near Balloch. We will confirm the plan with the fixed quote.

  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. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open
  • Explain the parking and delivery arrangements

Advice

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Maintenance after handover

To get the most from the new sealant:

  • Brief window cleaners about newly sealed joints
  • Ask about asbestos in pre-2000 mastic
  • Avoid patch repairs on failed facade joints
  • Record the product and colour used on each elevation

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

Questions we are asked in Balloch

Is hospital work, at somewhere like Vale of Leven District General Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Balloch off your patch?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

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.

Do you seal facades in winter?

Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated as the work goes on.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.

How long does a job like this take?

It depends on the scope, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

Will you just go over the old sealant?

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

Building and refurbishing in Balloch

Building work in Balloch comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. The mastic follows the specification that goes with the warrant. The west of Scotland, where Balloch is, gets more rain than the east. Outside mastic is booked around the forecast, and internal sealing fills the gaps.

Hotel extensions and refits, at places such as Lomond Park Hotel, which lies west of Balloch, normally run between busy periods, so the sealing is squeezed into short windows. New units and refits on sites such as Vale of Leven Industrial Estate, 2.5 miles south of Balloch, need their panel and perimeter joints sealed to the specification. On a healthcare site such as Vale of Leven District General Hospital, 1.1 miles to the south-west of Balloch, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Travel to remote or island sites
  • The product specified
  • The site’s rules and procedures
  • Whether the work must be split into stages

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Sending details for a quote

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

  • When you need the work done
  • Photos of the joints, close up and from further back
  • Specification clauses that apply
  • Whether an asbestos survey exists

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What we can’t put right

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

  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle
  • Replacing glass or failed glazing units

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

Joints and surfaces we work on

  • Cladding panel joints
  • Coping and flashing joints
  • Shopfront frames
  • Stone and brick facade joints
  • Window and door perimeters
