What we do, step by step
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Craigmillar, tell us the floor, how the door entry system works and where we can park nearby.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

About our window mastic in Craigmillar
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on uPVC windows, aluminium frames and patio & French doors, and common reasons people get in touch are water coming in at the bottom corners of a door and draughty joints inside around the window.
Craigmillar is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Your job is guaranteed for a year, as with all our work.

FAQs for Craigmillar
How do repairs to the shared parts of a tenement in Craigmillar get organised?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.
Can you help a landlord with a rental near Brunstane station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Use gentle cleaners on frames and sealant
- Check the mastic once a year
- Avoid harsh chemicals near the mastic
- Keep timber frames painted
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a tenement flat in Craigmillar, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

Craigmillar homes and the weather
Craigmillar is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces 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.
For an older house near a landmark such as Robin Chapel, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Brunstane station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Do you need window mastic in Craigmillar?
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
It’s worth asking for a quote if you see:
- Leaking joints at the ends of sills
- Cold air getting in at the frame edge
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
Managing a site like Castlebrae Community High School? Then its window and door frames need their mastic kept sound, just like a home’s.
