Sand mastic in Bridge of Orchy, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. We work on stone surrounds, period & listed homes and tenement windows, and people most often call us about window mastic to renew ahead of painting and draughts and rain around sash boxes.
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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours per window, depending on the condition of the joints. Outside jobs in Bridge of Orchy need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

Is it worth trying it myself?

Do you have insurance?
Yes. We’re fully insured.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Landlord and commercial work in Bridge of Orchy
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How the job changes by surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
What we are called out for in Bridge of Orchy
Timber frames move with the seasons. The movement cracks the mastic little by little.
It’s worth asking for a quote if you see:
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- Mastic that needs renewing before redecorating
- Draughts and rain around sash boxes
For landlords with property near Bridge of Orchy station, any sash windows need sound mastic to keep draughts and rain out.
Before booking anyone
- When the joint can take water or movement
- Whether the sealant suits the joint
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
