Mastic sealing in Arrochar, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you have worn sealant at communal door frames and no planned programme for sealant, we can help, on communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms alike. Looking for mastic applicators who cover Arrochar? We’ve been sealing commercial buildings since 2005.
Around smaller places such as Arrochar, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Exposed walls take Scottish weather hard, and frame mastic shows it first.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Quoting for work in Arrochar
A fixed quote reflects the actual work. It allows for:
- The site’s rules and procedures
- How much there is to seal
- Joint width, depth and condition
- Location, for remote and island sites
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What we need to price the job
To price the job accurately, we need to understand the site. Send us:
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- Photos of the joints, close up and from further back
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or use the quote form.
FAQs: Arrochar
Will you take on a block within reach of Arrochar & Tarbet station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Does the sea air around Arrochar change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Frames, entrances and external joints in Arrochar
The sea is no more than about 1 mile from Arrochar. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. The west of Scotland, where Arrochar is, gets more rain than the east. The weather side of a block typically needs attention first. Outside mastic goes on in dry spells, with some flexibility in the programme.
Trustees of buildings like Arrochar Church can bring frame and external mastic into a planned maintenance list.

When to call us in Arrochar
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
If one of these sounds familiar, it’s time for a closer look:
- Damaged joints in communal entrances and corridors
- Brittle perimeter mastic across a building
- Estate-wide sealant that is simply worn out
- Open joints in brickwork or panels
If you look after a block within reach of Arrochar & Tarbet station, 1 mile north-east of Arrochar, frame and balcony mastic can be renewed on one programme.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Asbestos-containing sealant, which we don’t remove
- Substrate edges that need repairing first
- Frames that are rotten, warped or broken
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly.
