Different surfaces, different methods
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.
Facade sealing for commercial buildings in Garnethill
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. We work on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints, and what we are called in for most is cladding panel joints that have opened up and air leaks through failed facade joints. A single leaking joint is often how a building in Garnethill first comes to us: we look at the rest while we’re there and tell you what we find.
City-centre sites in Scotland usually mean booked deliveries, tight storage and shared access. Our CSCS-carded applicators work to the site induction, the programme and the sequence of trades.
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.

What we’re called out for in Garnethill
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.
Most enquiries start with one or more of the following:
- Leaks at window and door perimeters
- Cladding panel joints that have opened up
- Weathered facade joints that have lost their grip
- Failed seals around shopfront and entrance frames
When a college such as City of Glasgow College - City Campus (to the east of Garnethill) builds or refurbishes, the mastic package normally has to fit around students and staff.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- Is the sealant right for the movement and the substrate?
- Can the work be phased to keep areas open?
- What site paperwork they can supply
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. City jobs in Garnethill usually need parking and loading planned. Shared closes, stairs and the property factor may need to be part of the plan.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
What we need from you
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work
- Tell us which areas need to stay in use

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Related advice
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Brief window cleaners about newly sealed joints
- Inspect facade joints on a regular cycle
- Share access with other external trades
- Ask about asbestos in pre-2000 mastic
Record the sealant type and date on the building file. Future work can then match the product and colour.
Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.

Questions we’re asked in Garnethill
Can you work at a site such as Oakbank Industrial Estate, by Garnethill?
Yes, sites like Oakbank Industrial Estate are within our area, along with the rest of Garnethill. Send details of the unit and the work through our quote form for a quick quote.
Can you work around term dates at a campus such as Glasgow Caledonian University?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work on upper floors?
We agree access with the client at the start. Let us know what access is in place or planned.
Do you run new sealant over the existing bead?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. That is what makes the new joint last.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can staff carry on working while you’re here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Is old mastic on our building likely to contain asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
