Landlords, agents and businesses in Fort Augustus
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Sand mastic in Fort Augustus
Across Fort Augustus, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and mastic worn away on windows facing the weather, across timber door frames, tenement windows and sash and case windows.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Whatever the size of the job, you get the same 12-month guarantee in Fort Augustus and across Highland.

How the job changes by surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Stone surrounds
The stone is treated with care when the old mastic comes out.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Timber that has rotted
- Putty and glazing repairs
- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
What we seal
- Sash and case windows
- Brick reveals
- Tenement windows
- Stone surrounds
- Period & listed homes
- Timber door frames
Signs you need sand mastic in Fort Augustus
Timber frames move with the seasons. That movement opens up the mastic joint over time.
The most common problems we see are:
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes
Schools such as Kilchuimen Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic in Fort Augustus: local notes
Many older homes in Scotland have sash and case windows, 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 failed outside joints work against that.
In and around Fort Augustus, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Common questions in Fort Augustus
Is there a guarantee on sand mastic in Fort Augustus?
All our work, in Fort Augustus and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you do sand mastic in Fort Augustus?
Yes. We work across all of Scotland, and Fort Augustus is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you work for landlords and businesses?
Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours per window, depending on the condition of the joints. Outdoor work around Fort Augustus depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
