How we handle construction mastic in Black Crofts
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. Most enquiries involve oversized or tapered gaps around new frames and failed sealant in an existing building being refurbished, on brick and block movement joints, cladding and panel joints and window and door perimeters. One point of contact handles commercial sealant work in Black Crofts from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For a site around Black Crofts, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Contractors’ notes for Black Crofts
Black Crofts lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Being in the west of Scotland, Black Crofts gets more rain than eastern areas. Outside mastic is booked around the forecast, and internal sealing fills the gaps.
On any site in or around Black Crofts, the mastic follows the specification and the programme. Hotels like Falls of Lora Hotel (1.3 miles south-west of Black Crofts) rarely close for long, so refurbishment mastic is phased floor by floor.
Black Crofts is about 40 miles north-west of Helensburgh, in Argyll and Bute. Black Crofts sits inside our coverage and the rest of Argyll and Bute, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Argyll and Bute, 124 places are covered, including Black Crofts. Our Glasgow page has more on work in that area, about 60 miles away.
Anyone looking for construction mastic in PA37 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside Black Crofts, we cover Ardchattan (1 mile north-east), North Connel (1 mile south-west), Connel (2 miles south-west), Benderloch (2 miles north-west) and Dunbeg (4 miles south-west). 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.

Surface by surface
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Specifying the product where the designer hasn’t
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Approving fire stopping as compliant
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think.
Surfaces we seal
- Floor and skirting junctions
- Internal decorators’ caulk
- Cladding and panel joints
- Brick and block movement joints
- Sanitary and kitchen joints
- Window and door perimeters
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- How accessible the joints are
- Whether old sealant has to be cut out first
We don’t publish prices, since every building and every scope is different. Call for a quote.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- What the building is and how it’s used
- The postcode of the building
- Any specification or named product
- Clear photographs of the problem areas
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, call the office on 01277 525 020 or email us.
Questions about Black Crofts
Is Black Crofts too far out for you?
No. Small places get the same service as large ones. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
Can being near the sea in Black Crofts affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can you fit around our programme?
We work to your programme. Share the release dates and we’ll match our work to them.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Are you CHAS accredited?
CHAS and Constructionline are both in place, and each applicator is CSCS-carded. We are fully insured for public liability.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Leave it or put it right?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple, with the same standard on every plot. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Black Crofts, a repair visit takes planning, so it’s better to act early.
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
