Mastic sealing in Kilbarchan
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: 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 along with complaints. Site teams most often ask us about cracked, hardened mastic round windows on a block and complaints coming in block by block, on window and door perimeters on blocks, balcony and threshold joints and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, in Kilbarchan it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Kilbarchan is planned with the forecast. Programmes allow for the weather.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: for example 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.
Surface by surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks from above rather than through a joint
- Broken glass or failed sealed units
If you’re not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Surfaces we seal
- Shopfronts below residential blocks

Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For work around Kilbarchan, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Before we start on site
- Move anything stored against the joints
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs

Advice
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Reduce knocks to communal area joints
- Avoid piecemeal callouts where you can
- Start inspections with the most exposed faces
- List the paperwork your organisation requires when you send details
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
