How we handle sand mastic in Queensferry
Across Queensferry, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on tenement windows, brick reveals and sash and case windows, and common reasons people get in touch are open joints round the window box and patchy fillers round a sash window.
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.
All our work is covered by a 12-month guarantee, wherever you are in Edinburgh.

How it works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a single window, longer for several for a typical job. Around Queensferry, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Why deal with it now?
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 an older home around Queensferry, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Queensferry questions
Will you come out to Queensferry?
Yes. Queensferry is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Dalmeny station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How long does sand mastic take?
It depends on the size of the job, but most jobs take a few hours for a single window, longer for several. We will give you a better idea when we quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Timber that has rotted
- Damaged stone surrounds
- Sashes that rattle, stick or will not open
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.

Surface by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.
What sand mastic looks like in Queensferry
Queensferry is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Dalmeny station change hands often, and any sash windows need sound mastic to keep draughts and rain out. In the older streets around Queensferry Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like Queensferry High School? Then its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
After the cure time, these simple habits help:
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Clear gutters so water does not pour onto the windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
What affects the cost of sand mastic
There’s no set price list. What we look at:
- The number of rooms or windows
