Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

About our sand mastic in Scatness
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you are redecorating. We work on brick reveals, sash and case windows and period & listed homes, and people most often call us about a silicone bead on a sash window that spoils the look and mastic that needs renewing before redecorating.
Mastic can only go onto a dry joint, so outside work in Scatness depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Whatever the size of the job, it’s backed by our 12-month guarantee in Scatness and across the Shetland Islands.

Surface by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
For landlords and businesses

Scatness homes and the weather
Scatness is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Island jobs need planning around ferries and the weather, so the more notice, the better.
For jobs in and around Scatness, choosing the right material for each joint is as important as a tidy finish.
