Sand mastic for homes and businesses in Kirbister
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. If you are dealing with a silicone bead on a sash window that spoils the look and mastic worn away on windows facing the weather, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a one-year guarantee.

Different surfaces, different methods
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Damaged stone surrounds
- Sash cords, weights and draught-proofing of the sashes

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Clear items away from the joints we are working on
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
Getting a quote
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

Kirbister homes and the weather
Kirbister 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. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For jobs in and around Kirbister, choosing the right material for each joint is as important as a tidy finish.
Kirbister is about 6 miles south-west of Kirkwall, in the Orkney Islands.

Why it’s worth doing now in Kirbister
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

How long does sand mastic take?
That depends on how much there is to do, but most jobs take a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Are you insured?
Yes. We’re fully insured for every job we do.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
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.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
