Sand mastic for sash & case windows in Portlethen Village, Aberdeen

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are 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.
About our sand mastic in Portlethen Village
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include a silicone bead on a sash window that spoils the look and tired mastic found when preparing windows for paint, on sash and case windows, period & listed homes and brick reveals.
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.
All our work is covered by a 12-month guarantee.

What sand mastic looks like in Portlethen Village
Portlethen Village is close to 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. 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.
If you look after a building such as Portlethen Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Portlethen station, any sash windows need sound mastic to keep draughts and rain out.
Portlethen Village is about 7 miles south of Aberdeen, in Aberdeen. Whether you’re in the middle of Portlethen Village or further out, we cover sand mastic for every kind of property. Portlethen Village is one of 63 towns and villages in Aberdeen where we work. For nearby work, see our Aberdeen page.

Well-known places in the area include Pitfoddels Castle (4.4 miles north). The countryside around Portlethen Village includes Blue Hill and Loirston Loch.
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Portlethen Village: your questions answered
Do you cover smaller places like Portlethen Village?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect sand mastic in Portlethen Village?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.

What we are called out for in Portlethen Village
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
People usually contact us when they notice something like this:
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
- Cement or filler used on old window joints that has cracked
- Mastic worn away on windows facing the weather
For an older house near a landmark such as Portlethen Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- How much experience the applicator has
- Whether you can choose the colour
- What the quote includes, VAT included or not
- How long to leave it before use
What the job involves on each surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
