Sand mastic in Stoneywood
We work across Stoneywood renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you have failed mastic on an exposed elevation and draughts and rain around sash boxes, we can help, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
- Crumbling stone or brickwork round the window
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Why it’s worth doing now in Stoneywood
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Find out about consent before window work on a listed home
- Take care around the mastic when scraping paint
- Don’t run silicone over sand mastic
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Stoneywood: your questions answered
Do you cover smaller places like Stoneywood?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Larbert station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will talk you through it.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
How long does the job take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer.
Frames and glazing around Stoneywood
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Larbert station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

It’s worth asking for a quote if you see:
- Cement or filler used on old window joints that has cracked
- Draughty sash windows at the surround
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
Managing a site like Denny High School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- What guarantee comes with the work
- Is the old sealant removed completely?
- What the cure time is
- Who does the work, and how experienced they are
The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a single window, longer for several, depending on the amount of work. Outside jobs in Stoneywood need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check each window surround and the condition of the joint.
- 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
- Tell us about any previous sealing or DIY attempts

- Keep pets and children clear of the area while we work
