Mastic sealing in Cliasmol
For blocks and buildings in Cliasmol and across Na h-Eileanan Siar, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on communal kitchens and washrooms, window and door perimeters on blocks and communal entrances and stairwells, and the failures we’re asked to look at most are communal area joints that look neglected and a mix of products and colours from past repairs. Looking for mastic applicators who cover Cliasmol? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Travel to smaller places like Cliasmol is planned so several buildings can be done on one trip. A list of addresses and photographs lets us quote for them together.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Questions about Cliasmol
Can one quote cover a number of our buildings near Cliasmol?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Can being near the sea in Cliasmol 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 work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Is Cliasmol in your area?
Yes. Sites across Cliasmol are covered, with one number for every area we cover.

What sets the cost
Each job is priced on its own details. The main factors are:
- Removal of failed or old sealant
- How much there is to seal
- Location, for remote and island sites
- The site’s rules and procedures
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- The postcode of the building
- Whether the building will be occupied during the work
- Specification clauses that apply
- Asbestos survey details if the building is older
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email drawings and photos with what you know.
Why act early in Cliasmol
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. For buildings near Cliasmol, dealing with all the failing joints at once saves return trips. Send photographs and we’ll quote for everything together.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Mastic sealing around Cliasmol: how the place shapes the job
Cliasmol lies within about 1 mile of the sea. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. For an island location such as Cliasmol, work is planned around ferry crossings and the weather. Send photos and addresses so every building can be covered on as few trips as possible.
Wherever your building is in or near Cliasmol, we look at the whole elevation before quoting, so you know what needs doing now. Owners near Cliasmol can renew frame and external mastic block by block on one programme.

Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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.
