How the job changes by surface
Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
Mastic sealing in Inverarnan, done properly
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you have open joints in brickwork or panels and occupiers reporting cold air round windows, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Inverarnan, preparation and product choice get the time they need.
Around Inverarnan, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Plan resealing building by building rather than complaint by complaint
- Ask residents or tenants to report leaks and draughts early
- Check sealant joints during planned building inspections
- Prioritise elevations facing the weather
If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it unless told otherwise.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
How the quote is worked out
We price every job individually. The main factors are:
- Joint width, depth and condition
- How much existing material needs removing
- Working within restricted access windows
- Induction, permit and paperwork requirements
A quote for mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Your programme or deadline
- What the building is and how it’s used
- Specification clauses that apply
- Whether an asbestos survey exists
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, give us a call on 01277 525 020 or email us.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or two for a single block, longer for an estate programme. Travel to smaller Scottish places like Inverarnan is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
- Have the specification and drawings to hand
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Why it’s worth doing now in Inverarnan
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Inverarnan, a repair visit takes planning, so it’s better to act early.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Questions about Inverarnan
Do you work for managing agents with blocks near Ardlui station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is Inverarnan too small for you to travel to?
No. Places such as Inverarnan are covered as much as the big towns. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
Can you send RAMS and CSCS details before starting?
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 will confirm with the quote.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you need mastic sealing in Inverarnan?
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
These are often picked up first by site or facilities staff:
- Damaged joints in communal entrances and corridors
- Old repairs sealed over failed mastic
- Draught complaints from residents or tenants
- Window mastic that has split and shrunk
If you’re responsible for a building such as Ardlui Church, frame and door mastic needs the same attention as any other property.
