About our sand mastic in Creetown
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include cement or filler used on old window joints that has cracked and window mastic to renew ahead of painting, on stone surrounds, timber door frames and sash and case windows.
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.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
FAQs for Creetown
Is Creetown within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do sand mastic in Creetown?
Yes. Our work covers the whole of Scotland, and Creetown is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is it worth trying it myself?
It depends on the job. 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.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How much does sand mastic cost in Creetown?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Looking after it afterwards
After the cure time, these simple habits help:
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Outdoor work around Creetown depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.

Creetown homes and the weather
Creetown 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 is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
In and around Creetown, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
