New build and refits around Rahane
The sea is no more than about 1 mile from Rahane. 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. The west of Scotland, where Rahane is, gets more rain than the east. External mastic dates are agreed with the site manager, with internal sealant kept ready for wet days.
Hospital estates such as Victoria Infirmary, 5.5 miles to the south-east of Rahane, 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.
Rahane is about 5 miles north-west of Helensburgh, in Argyll and Bute. We send applicators to Rahane for mastic packages. 124 places across Argyll and Bute fall within our area, Rahane among them. We also cover Glasgow, some 25 miles away.

Construction mastic for commercial buildings in Rahane
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on cladding and panel joints, sanitary and kitchen joints and brick and block movement joints, and what we are called in for most is different trades sealing to different standards and sealant knocked or painted over by other trades. Searching for sealant specialists in Rahane? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Rahane that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frame gaps too wide for sealant, which the installer needs to correct
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Surfaces we seal
- Cladding and panel joints
- Brick and block movement joints
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Internal decorators’ caulk
From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Where we can, we combine work around Rahane with other jobs nearby. Let us know if your dates have any give.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Tell staff and tenants when we’ll be in
- Tell us what induction or permit system the site runs
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

How the quote is worked out
What shapes the price:
- Travel to remote or island sites
- Joint width, depth and condition
- Removal of failed or old sealant
- Specialist products, such as fire-rated or hygienic sealants
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What to include in your enquiry
A few photographs plus some basic facts will normally do. Please tell us:
- How the joints are reached, and at what height
- What the building is and how it’s used
- Any dates the work must fit around
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Doing it in-house
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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Do you need construction mastic in Rahane?
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
Typical triggers for a call:
- Inconsistent sealant finishes from plot to plot
- Mastic snags holding up handover
- Internal caulk splitting as the building dries out
- Sanitary sealant damaged by following trades
Older buildings in the area around Rahane, such as Hill House, which lies south-east of Rahane, need care when sealed: the product has to suit soft or historic materials.
What to look for in a quote
- What site paperwork they can supply
- Their approach to joint depth and backing
- Do they follow the manufacturer’s priming guidance?
- How they’ll work around occupants
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Plan external elevations with the weather in mind
- Put any product change through the designer first
- Keep finished joints away from paint, plaster and scrapers
- Bring the mastic contractor in after the last trades are through
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We raise them during our first walk of the area.

Rahane: questions and answers
Is Rahane too far out for you?
Not at all. Rahane is within our area. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
Can you take on a job at a hospital such as Victoria Infirmary?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
What joints do you seal on a new build?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. The scope follows your specification.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
