Greenside Sand Mastic
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homes and businesses in Greenside and across Edinburgh. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Patchy fillers round a sash window
- Silicone on a period window that looks wrong
- Wind and rain getting in round a sash window
What we’re called out for in Greenside
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they usually need raking out.
The most common problems we see are:
- Cracked mastic round a front door frame
- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating
Managing a site like London Street Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Sand mastic in Greenside, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you are dealing with gaps between timber frames and stone or brick and mastic dropping out of the joint, we can put it right, on period & listed homes, brick reveals and tenement windows alike.
Sash and case windows are a feature of older tenements in all four Scottish cities, though many have since been replaced. In Greenside, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Landlords, agents and businesses in Greenside
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
When it is not the sealant
In fairness, some problems need a different trade:
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Greenside: your questions answered
I let a flat near Edinburgh Waverley station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Greenside?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Is the work guaranteed?
Every job comes with our one-year guarantee, and we are fully insured.
Do you have insurance?
Yes. We’re fully insured.

What happens if it’s left?
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Private landlords in Greenside must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.

Looking after it afterwards
After the cure time, these simple habits help:
- Avoid patching sand mastic with silicone
- Don’t paint over the new mastic
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Sand mastic in Greenside: local notes
Greenside is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Windows usually belong to the flat, but the title deeds have the final say.
For landlords with property near Edinburgh Waverley station, any sash windows need sound mastic to keep draughts and rain out. Homes close to St Cuthbert's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a single window, longer for several, depending on the amount of work. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Greenside, tell us the floor, how the door entry system works and where we can park nearby.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
