Sand mastic in Moredun, done properly
Across Moredun, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you are dealing with failed mastic on an exposed elevation and old sand mastic that has cracked, crumbled or fallen out, we can put it right, on tenement windows, stone surrounds and timber door frames alike.
Moredun is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What affects the cost of sand mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- The old material and how stubborn it is
- The product the joint needs
- The number of rooms or windows
- Whether there’s mould to deal with
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, drop us a line at info@mrmastic.co.uk.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Clear gutters so water does not pour onto the windows
- Find out about consent before window work on a listed home
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
What we’re called out for in Moredun
Water gets into small cracks in the mastic and loosens it further. Exposed elevations generally fail first.
Signs it’s time to call us include:
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
Schools such as Liberton High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Before you book anyone

- What preparation is included
- When the joint can take water or movement
- Whether VAT is included
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The process
At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on how much there is to do. In a city area like Moredun, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any tricky access
- Move anything stored near the joints
- Keep children and pets away from the work area

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Private landlords in Moredun must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Why us?
- More than 20 years in sealant work
- Any old sealant cut out fully, not covered over
- We’re fully insured
- Sanitary silicone with an anti-fungal additive in wet areas

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
What we seal
- Tenement windows
- Brick reveals
- Timber door frames
- Period & listed homes
- Stone surrounds
- Sash and case windows

Moredun questions
I let a flat near Shawfair station. Can you help?
Yes, we work for landlords and agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
How do repairs to the shared parts of a tenement in Moredun get organised?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Windows and doors in Moredun
Moredun is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds.
If you let a flat or house near Shawfair station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Liberton Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
