About our mastic sealing in Cornhill
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have estate-wide sealant that is simply worn out and no planned programme for sealant, we can put it right. Whoever orders the work in Cornhill, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Scotland’s city blocks are largely sandstone or, in Aberdeen, granite, so perimeter mastic around replacement windows has to be neutral-cure and kind to the masonry.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Work on a big city site in Scotland usually involves inductions and permits. Tell us the rules and we’ll work to them.
- 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.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work

Questions we’re asked in Cornhill
Do you work for managing agents with blocks near Aberdeen station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Who do we deal with for shared-part sealing on a tenement in Cornhill?
In most tenements, the owners agree shared repairs, and many use a property factor to arrange them. One quote can cover a close or the whole block.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you cover Cornhill?
Yes. We cover Cornhill, and the simplest way to start is to speak to us on 01277 525 020 or send photos by email.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
General trades versus a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Keeping the joints sound
To get the most from the new sealant:
- Include mastic in your cyclical inspections
- Reduce knocks to communal area joints
- Have the asbestos survey to hand for older buildings
- Track which buildings were done and when
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
Common problems we fix in Cornhill
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.
Clients normally get in touch after noticing something like this:
- Failed external movement joints
- A mix of products and colours from past repairs
- Mastic failing across several blocks on an estate
- Water getting in round frames after rain
Blocks of flats and mixed-use buildings often cluster around stations such as Aberdeen station, 1.8 miles south-east of Cornhill, and their window and balcony mastic tends to age at the same rate across a building.
What to look for in a quote
- How long is the guarantee, and what does it include?
- Will failed sealant be removed rather than covered?
- Their approach to joint depth and backing
- Will RAMS and insurance details be available?
Mastic sealing in Cornhill: the local picture
Cornhill lies within about 3 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. There are five care or nursing homes within about 2 miles of Cornhill. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
Site managers at schools like Northfield Academy can fit frame mastic into the summer works. Student blocks close to universities like University of Aberdeen - Foresterhill Campus, under half a mile to the south of Cornhill, are easiest to work on between tenancies.
Cornhill is about 1 mile north-west of Aberdeen, in Aberdeen. Looking for mastic sealing in Cornhill? We can help, as we do across Aberdeen. Across Aberdeen, 40 places are covered, including Cornhill.

Local landmarks in Cornhill
Around Cornhill, our work takes us to commercial buildings near Oakbank School, Gilcomstoun Primary School and Stewart Park and the streets around them. For rail, the closest station is Aberdeen station, roughly 1.8 miles south-east of the centre. A little further out are King's Museum (1.3 miles north-east) and Cowdray Medical Pavilion (less than half a mile south). Open spaces near Cornhill include Rubislaw Quarry and Gallows Hill.
Why deal with it now?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Failed sealant in a shared building in Cornhill can affect more than one owner, which makes early repair simpler for everyone. Fixing it promptly keeps repairs small.
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 rules also count.
