About our sand mastic in Provanhall
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. Common call-outs are for failed mastic on an exposed elevation and draughts and rain around sash boxes, on period & listed homes, sash and case windows and timber door frames.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
There’s a 12-month guarantee on every job, whatever its size.

What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
How long will you be here?
A typical job takes a few hours per window, depending on the condition of the joints. Your quote will say how long we expect yours to take.
How much does sand mastic cost in Provanhall?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Decisions on consent for listed homes
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. Outside jobs in Provanhall need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Frames and glazing around Provanhall
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. With historic houses such as Provand's Lordship (about 4.1 miles west) nearby, there’s older building stock in the area around Provanhall as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Saint Benedict's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Garrowhill station, any sash windows need sound mastic to keep draughts and rain out.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Plan mastic work ahead of painting
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Should I try it myself first?
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 doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens if it’s left?
Cement-based fillers and modern sealants don’t always suit a period 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: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
