About our sand mastic in Potarch
Across Potarch, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you have draughts and rain around sash boxes and mastic round period door frames that has failed, we can help.
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.
You get a one-year guarantee, the same in Potarch as everywhere else we work.

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Whether work needs listed building consent
- Crumbling stone or brickwork round the window
- Cracked or broken glass

Do you need sand mastic in Potarch?
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint and we normally remove them.
Any of these means the joints need attention:
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
Around Potarch, as everywhere, sand mastic is only as good as the preparation behind it.
Questions to ask before booking
- How long the guarantee is
- What insurance they hold
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Can I do it myself?
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.
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.
Common questions in Potarch
Is Potarch in your area for sand mastic?
Yes. We work across all of Scotland, and Potarch is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Is there a guarantee on sand mastic in Potarch?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Is sand mastic better than silicone for my windows?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What sand mastic looks like in Potarch
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
Whether the job is in Potarch itself or nearby, the right material for each joint matters as much as a neat finish.
