Signs you need facade sealing in Cornhill
Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and the joint opens with the first real movement.
Typical triggers for a call:
- Failed sealant on precast panel joints
- Failed seals around shopfront and entrance frames
- Sealant pulling away from frames or panels
- Discoloured or dirty facade joints
For contractors at a school such as Northfield Academy, sealing has to be finished before term starts.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- Their public liability cover
- Can the work be phased to keep areas open?
- What the guarantee covers, and for how long
Facade sealing in Cornhill
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. We work on stone and brick facade joints, coping and flashing joints and cladding panel joints, and the usual reasons a site gets in touch are perimeter sealant that has split or peeled away and failed sealant on precast panel joints. One point of contact handles commercial sealant work in Cornhill from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Sites in Scottish city centres tend to be hemmed in, with deliveries and storage to plan. We work to the programme and the site rules, with CSCS-carded applicators.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email the details over and we’ll come back to it.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Pass on the site’s contractor rules when you get in touch.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Getting the site ready
- Arrange parking or a loading space
- Move anything stored against the joints
- Tell us what induction or permit system the site runs

Advice
Mastic packages on Cornhill sites
Cornhill lies within about 3 miles of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. In Cornhill, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. We seal to the specification that sits behind the warrant.
Hospital estates such as Royal Cornhill Hospital, 0.7 miles south-east of Cornhill, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. When units on a site such as Kittybrewster Shopping Centre, 0.7 miles east of Cornhill, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Cornhill is about 1 mile north-west of Aberdeen, in Aberdeen. We cover Cornhill and the rest of Aberdeen, with the same fixed quotes and 12-month guarantee as everywhere else. Our Aberdeen coverage takes in 40 places, from busy centres to rural villages.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Arranging specialist high-level access, which is planned with the client
- Cracked or spalling substrates that need repair before sealing
- Joints too narrow for the movement they take, which need redesign
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Your questions answered
Will you plan work around the academic year at somewhere like University of Aberdeen - Foresterhill Campus?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Who do we deal with for shared-part sealing on a tenement in Cornhill?
Typically the owners agree it together, and a property factor often handles the arrangements. Send details and photos, and we will quote to whoever is arranging it.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Confirm the survey covers external sealants in older buildings
- Brief window cleaners about newly sealed joints
- Report water ingress at frames as soon as it shows
- Note when each elevation was last resealed
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
What affects the price in Cornhill
We price every job individually. The things that drive the figure:
- Phasing around occupants
- Which sealant the job calls for
- How much there is to seal
- Joint width, depth and condition
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
