Sand mastic in Juniper Green, done properly
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Common call-outs are for a silicone bead on a sash window that spoils the look and window mastic to renew ahead of painting, on sash and case windows, tenement windows and brick reveals.
In and around a place like Juniper Green, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Different surfaces, different methods
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Juniper Green: your questions answered
Will you come out to Juniper Green?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Juniper Green for sand mastic?
Yes, Juniper Green is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Is it possible to take out silicone and use sand mastic instead?
In most cases. We remove the silicone and clean the joint before the sand mastic goes in.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Juniper Green.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

What else we do in Juniper Green
Why deal with it now?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
