Sand mastic for homes and businesses in Gorebridge
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we will explain which is best for yours. If you have old sand mastic that has cracked, crumbled or fallen out and gaps where the frame meets the masonry, we can help, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
When to call us in Gorebridge
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Common reasons people contact us are:
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
For site and facilities teams at buildings such as Newbattle Community High School, its window and door frames need their mastic kept sound, just like a home’s.

- How the colour is chosen
- Whether the sealant suits the joint
- How much experience the applicator has
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. Outside jobs in Gorebridge need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Move anything stored near the joints

Advice
What sand mastic looks like in Gorebridge
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Rented homes near Gorebridge station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Gorebridge Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Where is Mr Mastic based?

Is sand mastic better than silicone for my windows?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
Is consent needed for window work on a listed home?
Check with your local planning authority. They decide whether consent is needed for work to your windows.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we will tell you how long to expect.
What the job involves on each surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Gorebridge, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
