About our construction mastic in Shandon
We work to the specification and the programme. Where the specification names a product, we use it. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. The enquiries we see most involve a mastic package split between trades with no clear owner and failed sealant in an existing building being refurbished, across cladding and panel joints, sanitary and kitchen joints and window and door perimeters. Most enquiries from Shandon start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sites near smaller places like Shandon can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
A 12-month guarantee applies to all our work in Argyll and Bute. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we will come back to it.

Questions we’re asked in Shandon
Can you work on a hospital site such as Victoria Infirmary?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Shandon outside your area?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Our process
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Where we can, we combine work around Shandon with other jobs nearby. Let us know if your dates have any give.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
What we need from you
- Explain the parking and delivery arrangements
- Tell staff and tenants when we’ll be in
- Send your site hours and access windows

Related advice
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Get the mastic subcontractor involved early in the programme
- Check frame gaps are within the sealant’s range before sealing
- Keep scrapers and abrasive pads off new beads
- Don’t force external sealing on a damp or frosty day
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
How the job changes by surface
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team before sealing starts.
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.
Contractors’ notes for Shandon
Shandon sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Shandon is on Scotland’s wetter western side. We keep internal mastic in hand so wet days aren’t lost.
Hotels like Rosslea Hall Hotel (1.4 miles south of Shandon) rarely close for long, so refurbishment mastic is phased floor by floor. Hospital estates such as Victoria Infirmary, 3.9 miles south-east of Shandon, 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. Historic houses such as Hill House, 2.9 miles south-east of Shandon, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

- Joint width, depth and condition
- Phasing around occupants
- Site requirements such as inductions and permits
- Location, for remote and island sites
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The product your specification calls for
- Any dates the work must fit around
- How the joints are reached, and at what height
- The asbestos register, for older buildings
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email a schedule or drawings.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Oversized gaps that need packing or adjustment by others
- Deciding which fire-stopping product a penetration needs
- Specifying the product where the designer hasn’t
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think before you book.
