Sand mastic for homes and businesses in Kingswells
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. Typical jobs include mastic worn away on windows facing the weather and crumbling sand mastic round a window, across period & listed homes, sash and case windows and brick reveals.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. Whether you are in a tenement flat or a house in Kingswells, the joint between frame and wall is what keeps the weather out.
All our work comes with a 12-month guarantee, wherever you are in Aberdeen.

Your questions about sand mastic in Kingswells
I let a flat near Dyce station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Kingswells?
The owners of the flats generally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you work in Kingswells?
Yes. We are based in Crawley and work across South East England, London and Scotland, Kingswells included.
Do you offer different sealant colours?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before work begins.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
How long does sand mastic take?
Most jobs take a few hours per window, depending on the condition of the joints. Your quote will say how long we expect yours to take.
Is consent needed for window work on a listed home?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Aftercare tips
A little care helps the new joints last. We recommend:
- Get any rot dealt with first
- Don’t paint over the new mastic
- Keep modern sealant off the mastic
- Ask the planning authority about consent for listed or conservation-area homes
Avoid painting over the new mastic, which is the traditional advice. If you’re redecorating, ask us first.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
When something else is needed
A few problems are outside what sealant work can do:
- Timber that has rotted
- Damaged stone surrounds
- Putty and glazing repairs
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

Do you need sand mastic in Kingswells?
Water gets into small cracks in the mastic and pushes it out. Exposed elevations usually fail first.
The most common problems we see are:
- Mastic dropping out of the joint
- Patchy fillers round a sash window
- Cracked mastic round a front door frame
- Tired mastic found when preparing windows for paint
Managing a site like Hazlehead Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Windows and doors in Kingswells
Aberdeen’s nickname, the Granite City, comes from its stone buildings, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip. With historic houses such as Friendville (about 3.6 miles south-east) nearby, there’s older building stock in the area around Kingswells as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church Of Scotland, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Dyce station, older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
