Surface by surface
External movement joints
Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Mastic sealing in Stronmilchan, done properly
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. If you have leaks at window and door perimeters and a mix of products and colours from past repairs, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Stronmilchan, that means joint design, primers and backing rod as standard.
In smaller Scottish places like Stronmilchan, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic normally fails first.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites around Stronmilchan. Several sites can go on one quote, which keeps the paperwork simple.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Track which buildings were done and when
- Check the asbestos register before any old mastic is disturbed
- Make it easy for occupiers to report draughts
- Reduce knocks to communal area joints
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Your questions answered
We manage a building near Dalmally station. Can you help?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Stronmilchan too far out for you?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What about access for upper-floor joints?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Can you reseal a whole block or estate?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
