How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Travel to smaller Scottish places like Cardross is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work
- Move anything stored against the joints

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Look at the sunniest and most exposed elevations first
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
- Group repairs into a planned programme
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer.
Surfaces we seal

Mastic sealing in Cardross: the local picture
Cardross is within about 1 mile of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. The west of Scotland, where Cardross is, gets more rain than the east. The weather side of a block usually needs attention first. Programmes allow for wet days.
With historic buildings such as Hill House (to the north-west of Cardross) in the wider area, owners of older properties around Cardross should expect mastic to need a product that suits old masonry. Churches, halls and community buildings such as Parish Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If you look after a block within reach of Cardross station (less than half a mile south of Cardross), frame and balcony mastic can be renewed on one programme.
Cardross is about 3 miles north of Port Glasgow, in Argyll and Bute. Our applicators travel to Cardross for work on mastic joints. Our Argyll and Bute coverage takes in 124 places. For work in that direction, see our Glasgow page, about 17 miles away.
Anyone looking for mastic sealing in G82 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Buildings on Station Road, Muirend Road and Fernie Gardens are within our area for mastic joints. Nearby places we also cover include Colgrain (2 miles north-west), Woodhall (2 miles south), Castlehill (2 miles south-east), Port Glasgow (3 miles south) and Bogston (3 miles south-west). Bigger towns within reach include Helensburgh (4 miles north-west), Dunoon (11 miles west), Rhu (6 miles north-west), Garelochhead (11 miles north-west), Sandbank (11 miles west) and Innellan (13 miles south-west). Cardross is one of the busier places in Argyll and Bute, and we take on mastic joints for its commercial and public buildings.

Different surfaces, different methods
Tenement and older buildings
Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
Questions we are asked in Cardross
We manage a building near Cardross station. Can you help?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is a smaller place like Cardross outside your area?
No. Places such as Cardross are covered as much as the big towns. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Cardross before they leak.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
