Mastic man in Aberdeen

Mastic and sealant work in Aberdeen

We cover Aberdeen and Aberdeenshire for every kind of sealant job: baths, showers and kitchens resealed, window and door mastic replaced, external joints sealed and sash and case windows pointed with sand mastic. We work for homeowners, landlords, hotels and businesses. Kitchens are part of it too: worktops, upstands and sinks are resealed with a colour-matched sealant, food-safe beside the sink where it’s needed.

The method doesn’t change because the stone does. Old sealant is cut out, the joint is cleaned back to sound material and dried, and the new sealant is chosen for what it has to stick to. In Aberdeen, that is very often granite.

Granite tenements, terraces and newer estates

Aberdeen is known as the Granite City, and its grey granite tenements, terraces and villas give it a look like nowhere else. In the centre and areas such as Rosemount and the West End, many homes are granite tenement flats or large granite terraces, often with sash and case windows. Further out, post-war housing and modern estates bring a mix of harled walls, brick and newer window frames.

Granite is hard and dense, but the joints around it still move. Window frames expand and shrink, and the mastic between timber and stone dries and cracks with age. Where original sash and case windows survive, burnt sand mastic is the traditional pointing. Where windows have been replaced, we use a flexible modern sealant that bonds well to stone. Our guide on mastic on granite and sandstone covers the detail.

Inside, tenement flats share a weakness found across Scotland: a failed bath or shower seal leaks into the flat below. We fill the bath before resealing, use flexible anti-fungal silicone and check tray and screen joints, because small gaps there are a common leak path.
