Sand mastic in Crieff
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We’re often asked to deal with draughty sash windows at the surround and patchy fillers round a sash window, across timber door frames, stone surrounds and sash and case windows.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Common questions in Crieff
Can you do sand mastic in Crieff?

Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you replace silicone on a period window with sand mastic?

What’s sand mastic made of?

How the job changes by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Stone surrounds
The stone is treated with care while raking out the old mastic.
Why deal with it now?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. In a place like Crieff, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Crieff homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In the older streets around St Michael's Hall, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Morrison's Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

What else we do in Crieff
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
