Grantshouse Window Mastic
Our applicators work in Grantshouse on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

About our window mastic in Grantshouse
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Typical jobs include gaps left after new windows were fitted and whistling draughts around closed windows, on timber windows & doors, composite doors and aluminium frames.
In and around a place like Grantshouse, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Every job comes with a 12-month guarantee, wherever you are in the Scottish Borders.

Questions from Grantshouse
Do you cover Grantshouse for window mastic?
Yes, Grantshouse is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Will you come out to Grantshouse?

What does window mastic cost?
It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Are you insured?
Yes. We’re fully insured.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Looking after it afterwards
Aftercare is simple:
- Use gentle cleaners on frames and sealant
- Paint up to the joint, not over it
- Check the mastic once a year
- Do not aim a pressure washer at the joints
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

Grantshouse homes and the weather
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Letting a property close to Reston station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Do you need window mastic in Grantshouse?
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
These are the problems we’re asked about most:
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
- A bead that does not match the frame
Homes close to Grantshouse Church (Church Of Scotland) include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
