About our mastic sealing in Duntocher
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. We work on external wall and movement joints, communal entrances and stairwells and shopfronts below residential blocks, and what we’re called in for most is damp patches beside frames and failed external movement joints. Facilities teams, main contractors and managing agents in Duntocher tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Duntocher is planned with the forecast. We agree a window with some flexibility.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Is mastic sealing guaranteed?

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.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Surface by surface
External movement joints
External movement joints take up expansion and contraction. Once that sealant goes, rain can reach the wall.
Planned maintenance
We can work into your cyclical maintenance plan, building by building.
From enquiry to sign-off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in 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. Where we can, we combine work around Duntocher with other jobs nearby. Let us know if your dates have any give.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.

Advice
Why it’s worth doing now in Duntocher
Failed perimeter mastic lets cold air in around frames and the windows usually get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Duntocher, a repair visit takes planning, so it’s better to act early.
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

For owners and agents in Duntocher
Duntocher is within about 3 miles of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Being in the west of Scotland, Duntocher gets more rain than eastern areas. The most exposed elevations need checking most often. Outside mastic goes on in dry spells, with some flexibility in the programme.
Blocks of flats and mixed-use buildings often cluster around stations such as Kilpatrick station, 1.5 miles to the south-west of Duntocher, and their window and balcony mastic tends to age at the same rate across a building. Site managers at schools like Clydebank High School can fit frame mastic into the summer works.
Duntocher is about 1 mile north of Clydebank, in West Dunbartonshire. Any commercial site in Duntocher is covered, whether it’s a single job or part of a planned programme. Our West Dunbartonshire coverage takes in 22 places. There’s a separate page for Glasgow, roughly 8 miles from Duntocher.
