Mastic sealing near Lìonal
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What we are called out for in Lìonal
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.
These are often picked up first by site or facilities staff:
- Damp patches beside frames
- Complaints coming in block by block
- A mix of products and colours from past repairs
- Open joints in brickwork or panels
Owners near Lìonal can renew frame and external mastic block by block on one programme.

Mastic sealing in Lìonal
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you are dealing with complaints coming in block by block and draught complaints from residents or tenants, we can put it right, on window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lìonal, that means joint design, primers and backing rod as standard.
Travel to smaller places like Lìonal is planned so several buildings can be done on one trip. A list of addresses and photos lets us quote for them together.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Track which buildings were done and when
- Start inspections with the most exposed faces
- Plan resealing building by building rather than complaint by complaint
- Encourage occupiers to report problems at frames
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
What affects the price in Lìonal
Each job is priced on its own details. The things that drive the figure:
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- How accessible the joints are
- Removal of failed or old sealant
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
- What the building is and how it’s used
- The product your specification calls for
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email the details over if you’d rather talk the job through.
How a job runs
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Travel to smaller Scottish places like Lìonal is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Explain the parking and delivery arrangements
Getting a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send details through our quote form.
Related advice
Lìonal: questions and answers
Does the sea air around Lìonal change the choice of sealant?
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.
Can you take on a job in Lìonal, on the island?
Yes, Lìonal is within the area we cover. We cover the whole of Scotland. We group island work where we can and plan around the crossings.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Who decides which product is used?
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.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
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 everything comes out first.
Planned mastic for Lìonal portfolios
Lìonal is within about 1 mile of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Island jobs, Lìonal among them, are planned around the ferry and the forecast. Send photographs and addresses so every building can be covered on as few trips as possible.
Schools and community buildings such as Lionel School need frame and external mastic kept sound like any building.
Lìonal (Gaelic: Lionel) is in Na h-Eileanan Siar. Our applicators travel to Lìonal for work on mastic joints. We work across 87 places in Na h-Eileanan Siar, from busy centres to rural villages.

- Broken glass or failed sealed units
- Frames that are rotten, warped or broken
