Mastic man in Dundee

Mastic and sealant work in Dundee

We cover Dundee and the surrounding area for bath and shower resealing, kitchen sealant, window and door mastic, sand mastic pointing and external joints. Whether it’s a tenement flat in the West End, a family home in Broughty Ferry or a student let near the universities, the work is done the same careful way.

All old sealant comes out, because new silicone won’t stick to old. The joint is cleaned, any mould is treated, and the new bead is chosen for the surface and the movement it has to handle. Inside, that is usually anti-fungal sanitary silicone; outside, a flexible weatherproof sealant set at the right depth.

Sandstone tenements and Victorian villas

Dundee grew rapidly in the 19th century on the jute trade, and much of the housing from that time still stands: sandstone tenements in the West End, Lochee, Stobswell and the Hilltown, and large villas in Broughty Ferry and on the slopes above the Tay. Many still have sash and case windows set into stone.

Tenements in Dundee share the same risk as those in Glasgow or Edinburgh. A failed seal around a bath or shower lets water into the floor, and it can reach the flat below. We reseal with the bath filled, use flexible anti-fungal silicone and pay close attention to shower tray corners and screen edges.

Around original timber windows in sandstone, traditional burnt sand mastic is often the right pointing, and our sand mastic page explains it. Post-war and newer homes across the city have uPVC frames whose mastic is now hard and cracked, and we replace it with a flexible, weatherproof sealant in a colour to suit the frame, using backing rod where the gap is deep.
