Mastic sealing in Appin, done properly
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you have damp patches beside frames and estate-wide sealant that is simply worn out, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Appin it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places such as Appin, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic typically fails first.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Common questions from Appin clients
Our building in Appin is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Appin too small for you to travel to?
No. Places such as Appin are covered as much as the big towns. We cover the whole of Scotland. Good photos up front let us bring everything on the first visit.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Can people stay in the building while you reseal?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Common problems we fix in Appin
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
Common reasons buildings call us in:
- Repeated reactive repairs to the same buildings
- Estate-wide sealant that is simply worn out
- Draught complaints from residents or tenants
- Cracked, hardened mastic round windows on a block
Older community buildings, Appin Parish Church among them, often have frames of mixed ages whose mastic varies.
Questions to ask before you book
- Will RAMS and insurance details be available?
- Whether their applicators hold CSCS cards
- Proof of insurance
- The terms of the workmanship guarantee
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Misted or failed double-glazed units
- Frames that are rotten, warped or broken
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Cost factors for mastic joints
Before we quote, we look at:
- Travel to remote or island sites
- Quantities, in metres or numbers
- Access and working height
- How much existing material needs removing
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- Whether an asbestos survey exists
- A wide shot and a close-up of the area
- What the building is and how it’s used
- When you need the work done
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
