Sand mastic in Cullivoe
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with wind and rain getting in round a sash window and mastic dropping out of the joint, we can help, whatever the surface.
In and around a place like Cullivoe, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Our work is backed for twelve months.

Windows and doors in Cullivoe
Cullivoe is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near St Olaf's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Your questions about sand mastic in Cullivoe
Will you come out to Cullivoe?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Cullivoe affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames normally get a flexible sealant.
What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Do you need sand mastic in Cullivoe?
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
The most common problems we see are:
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
In and around Cullivoe, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Cullivoe
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. Around Cullivoe, 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.
What it costs depends on the size of the job, 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.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
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.
What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Outdoor work around Cullivoe 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.
