Sand mastic for homes and businesses in Auchinairn
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for weathered mastic on the most exposed windows and cracked mastic round a front door frame, on brick reveals, timber door frames and period & listed homes.
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.
You get a 12-month guarantee, the same in Auchinairn as everywhere else we work.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. For a place like Auchinairn, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

How we quote for sand mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- Access and height
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
What to tell us when you ask for a quote:

Why it’s worth doing now in Auchinairn
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. In a place like Auchinairn, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What sand mastic looks like in Auchinairn
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Schools such as Bishopbriggs Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Bishopbriggs station? Then any sash windows need sound mastic to keep draughts and rain out. Homes close to Colston Wellpark Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
Looking after new joints is easy:
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Ask a joiner to look at soft timber first
- Ask the planning authority about consent for listed or conservation-area homes
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
