About our sand mastic in Kirkpatrick-Fleming
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on sash and case windows, brick reveals and period & listed homes, and people most often call us about gaps between timber frames and stone or brick and mastic dropping out of the joint.
In and around a place like Kirkpatrick-Fleming, 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 a one-year guarantee.

Why deal with it now?
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. In a place like Kirkpatrick-Fleming, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why choose Mr Mastic in Kirkpatrick-Fleming

DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.

Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
Most people get in touch when they notice one of these:
- Weathered mastic on the most exposed windows
- Wind and rain getting in round a sash window
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look

Sand mastic in Kirkpatrick-Fleming: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Letting a property close to Gretna Green station? Then any sash windows need sound mastic to keep draughts and rain out.

What happens on the day
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours per window, depending on the condition of the joints. Outside jobs in Kirkpatrick-Fleming need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure water runs off the sill
- Don’t paint over the new mastic
- Keep modern sealant off the mastic
- Sort the mastic before the decorators arrive
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
