Sand mastic in Blackridge
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. Common call-outs are for mastic dropping out of the joint and failed mastic on an exposed elevation, on period & listed homes, sash and case windows and tenement windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Common questions in Blackridge
Is Blackridge within the area you cover?
Yes, Blackridge is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Blackridge in your area for sand mastic?
Yes, Blackridge is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and finished to sit neatly against the masonry.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Common problems we fix in Blackridge
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Look out for any of the following:
- Draughty sash windows at the surround
- Crumbling sand mastic round a window
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
Managing a site like Armadale Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in Blackridge
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a single window, longer for several in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
