Sand mastic for sash & case windows in St Cyrus, Aberdeenshire
Sand mastic in St Cyrus from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Draughts and rain around sash boxes
- Patchy fillers round a sash window
- Silicone on a period window that looks wrong
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Sand mastic in St Cyrus
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on timber door frames, tenement windows and stone surrounds, and common reasons people get in touch are mastic worn away on windows facing the weather and tired mastic found when preparing windows for paint.
In and around a place like St Cyrus, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
All our work is covered by our one-year guarantee, wherever you are in Aberdeenshire.

When to call us in St Cyrus
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
For an older house near a landmark such as St Cyrus Uf Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

St Cyrus: your questions answered
Will you come out to St Cyrus?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in St Cyrus affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What do you need from me for a quote?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is sand mastic better than silicone for my windows?
We will talk it through with you. Sand mastic suits many period homes and newer frames suit modern sealant.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you are set on DIY, put the effort into 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.

Sand mastic in St Cyrus: local notes
St Cyrus is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Rented homes near Montrose station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
St Cyrus is about 4 miles north-east of Montrose, in Aberdeenshire. We carry out sand mastic for homes and businesses in St Cyrus and the surrounding area, as part of our work across Aberdeenshire.

What the job involves on each surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. Around St Cyrus, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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.
- We finish the mastic to a tidy line.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
