Sand mastic in Backmuir of Pitfirrane, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you are dealing with gaps between timber frames and stone or brick and weathered mastic on the most exposed windows, we can put it right.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
There’s a 12-month guarantee on every job, large or small.

I let a flat near Dunfermline City station. Can you help?

Is Backmuir of Pitfirrane within the area you cover?

Do you work for hotels and businesses?

Can you seal over the old sealant?

When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Is the work guaranteed?
Our 12-month guarantee covers every job, sand mastic included.
What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- 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

- Tell us about any water getting in

Sash and case windows

Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.

Backmuir of Pitfirrane homes and the weather
Backmuir of Pitfirrane is within about 3 miles 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. Historic houses like Pittencrieff House (about 1.8 miles south-east) are a reminder that the area around Backmuir of Pitfirrane has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Queen Anne High School Dunfermline are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Pittencrieff House, about 1.8 miles south-east, is one of the historic houses in the wider area around Backmuir of Pitfirrane, and older homes nearby need a sealant that suits their walls.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
If you’re 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 fails, we can still redo it.
Aftercare tips
So the new joints stay in good condition:
- Do not run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Look over the window mastic once a year
- Renew mastic before redecorating the windows
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
