About our sand mastic in Kingseat
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on tenement windows, period & listed homes and stone surrounds, and common reasons people get in touch are gaps between timber frames and stone or brick and silicone on a period window that looks wrong.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You get a 12-month guarantee, the same in Kingseat as everywhere else we work.

What affects the cost of sand mastic
There’s no set price list, because no two jobs are the same. What we look at:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- How much there is to do
- Mould in or behind the old joints
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Kingseat: your questions answered
I let a flat near Dyce station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you do sand mastic in Kingseat?
Yes, Kingseat is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.

What else we do in Kingseat
Why it’s worth doing now in Kingseat
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. Around Kingseat, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Take a look at what affects the cost and our reviews.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into 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 to call us in Kingseat
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
Signs it’s time to call us include:
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
Schools such as New Machar Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Whether they’re fully insured
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
- When the joint can take water or movement
Looking after it afterwards
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Do not run silicone over sand mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Windows and doors in Kingseat
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. 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.
Letting a property close to Dyce station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Newmachar Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

What we do, step by step
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. Outdoor work around Kingseat depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on
