Commercial sealant contractors in Aberdeen
Aberdeen’s nickname, the Granite City, comes from the grey stone that gives its buildings a hard, durable face. That durability does not extend to the joints. Mastic between granite and window frames, movement joints in newer blockwork and cladding, and seals in washrooms and plant areas all wear out in the North East’s cold, windy climate. We cover Aberdeen, Aberdeenshire and the rest of Scotland for commercial clients and contractors.
Typical requests include window and door perimeter resealing, external movement joints, floor joints in workshops and warehouses, fire-rated sealing at service penetrations where specified, and washroom and changing room sealing. Send your details, get a fixed quote, and we seal the joints and back the work with a 12-month guarantee. Start with the quote form.
Granite buildings, offices and blocks
Granite is dense and hard-wearing, but it is unforgiving if a joint is prepared badly. Every trace of the old mastic must be removed, the stone face must be sound and dry, and a primer is used where the sealant maker specifies one for that substrate. On granite fronts a neutral-cure sealant is the normal choice, with a colour chosen to sit quietly against the grey; see facade and window perimeter sealing.
The city centre mixes traditional granite terraces and tenements with later office blocks, many built during the growth of the oil and gas industry. Those offices often have panel or cladding joints and window perimeters that have been resealed once already, or never at all. Where buildings are older, the asbestos register should be checked before old mastic is disturbed; why old mastic may be hazardous is covered in our guide.
Housing associations, councils and factors in Aberdeen look after flatted blocks, granite tenements and sheltered housing, each with communal windows, doors and external joints. Our mastic sealing service can be planned as a programme across a building or an estate, and housing and factors covers how we work with agents.
North Sea weather and short winter days
With the North Sea on its doorstep, Aberdeen gets weather that can be cold, windy and changeable. Exposed elevations take wind-driven rain and salt-laden air, which test both the sealant and its bond to the frame. Low temperatures and frosty mornings can push the start of external work back, and in midwinter the short daylight hours limit how much external sealing fits into a day. We plan around those limits and keep internal work for days when the outside joints are too wet or cold.
Choosing the right product for an exposed joint matters here: a sealant with the right movement capability for the joint, a correctly sized backing rod and good tooling all help it cope with the conditions. Our guide to joint width, depth and backing explains the basics.
Energy sector, industry, campuses and healthcare
Aberdeen’s economy has long been tied to the energy industry, and the city is ringed by industrial estates, workshops, yards and offices serving it. Workshop and warehouse floors take forklift and heavy plant traffic across saw-cut joints, so our floor joint sealing service is a natural fit; see also industrial units and warehouses. The harbour sits close to the city centre and its buildings face the full force of the coastal weather.
Robert Gordon University and the University of Aberdeen run large estates, and Aberdeen Royal Infirmary at Foresterhill is a major hospital site where infection control and occupied areas shape the work (healthcare). Hotels, shopping centres and restaurants in the centre need washroom and kitchen sealing that can be phased around trading.
Workshops and yards often have large welfare blocks with changing rooms and showers used by shift crews. Mould grows into sanitary sealant in busy wet areas and usually can’t be cleaned out, so the joints are cut out and replaced with anti-mould silicone. Main contractors building new offices, housing or industrial units across Aberdeen and Aberdeenshire can also pass us the mastic package, sealed to the programme and the specification; see construction mastic.

Questions from Aberdeen
Do you cover Aberdeen and Aberdeenshire?
Yes. We cover Aberdeen, Aberdeenshire and every other council area in Scotland.
What goes into joints on granite?
Normally a stone-compatible neutral-cure sealant, with a primer where the manufacturer specifies one. Acetoxy silicone is avoided on stone because it can mark or attack some surfaces.
Can you seal workshop and warehouse floor joints?
Yes. We use the right filler or sealant for the traffic and movement, phase the work so areas stay in use, and tell you if joint edges need repairing before sealing.
Will the weather delay external work?
It can. Sealant needs a dry joint within the product’s temperature range, so cold, wet or frosty conditions may hold work back. We plan for that and switch to internal work where possible.
Do you install fire-rated sealant in offices and plant rooms?
Yes, where it is specified. We install fire-rated and intumescent sealant at service penetrations and linear gaps to the manufacturer’s tested details. The designer and building warrant process set what is required.
Can you supply RAMS and insurance details?
Tell us what site paperwork you need, such as RAMS, our insurance certificate or CSCS details, and we’ll list what we can provide alongside the price.
Can you reseal communal windows in granite tenements for factors?
Yes. We can price a single stair, a whole building or a programme across a factor’s portfolio. Old mastic is cut out, the granite and frames are cleaned and dried, and the joints are resealed with a product that suits the stone.
Is the work guaranteed?
Yes. Our workmanship carries a 12-month guarantee.
