Common questions in Longmorn
Is Longmorn within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Elgin station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will advise.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Sand mastic for homes and businesses in Longmorn
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We are often asked to deal with mastic round period door frames that has failed and mastic dropping out of the joint, across sash and case windows, stone surrounds and brick reveals.
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.
Whatever the size of the job, you get the same 12-month guarantee.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours per window, depending on the condition of the joints. Outdoor work around Longmorn depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cracked or broken glass
- Sashes that need overhauling
- Masonry that needs repairing
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Surfaces we seal
- Sash and case windows
- Brick reveals
- Period & listed homes
- Tenement windows
- Stone surrounds
- Timber door frames
Frames and glazing around Longmorn
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. 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.
If you let a flat or house near Elgin station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Surface by surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Why it’s worth doing now in Longmorn
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
