About our sand mastic in Pathhead
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you have gaps between timber frames and stone or brick and tired mastic found when preparing windows for paint, we can put it right, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Pathhead is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, you get the same one-year guarantee.

How we quote for sand mastic
The price is agreed before any work begins. It’s based on:

- The number of rooms or windows
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What sand mastic looks like in Pathhead
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Around Pathhead, as everywhere, sand mastic is only as good as the preparation behind it.

Why act early in Pathhead
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Common problems we fix in Pathhead
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they generally need raking out.
It’s worth asking for a quote if you see:
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
- Silicone on a period window that looks wrong
- Mastic dropping out of the joint
Rented homes near Gorebridge station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

How the job changes by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
How the visit works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours for a single window, longer for several, and we tell you how long to leave it before we go. Outdoor work around Pathhead depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.

It depends on the job, so we quote each one individually. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Should I use sand mastic or silicone?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
