Sand mastic in Marchmont, done properly
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on stone surrounds, period & listed homes and timber door frames, and people most often call us about crumbling sand mastic round a window and mastic round period door frames that has failed.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Marchmont, and in a tenement the outside of the building may be a shared repair.
Whatever the size of the job, it’s backed by our one-year guarantee.

What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. In a city area like Marchmont, 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 start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Advice
Landlord and commercial work in Marchmont
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Clear gutters so water doesn’t pour onto the windows
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
- Don’t paint over the new mastic
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Frames and glazing around Marchmont
Marchmont is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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. Windows normally belong to the flat, but the title deeds have the final say.
For an older house near a landmark such as West St Giles' Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Edinburgh Waverley station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Signs you need sand mastic in Marchmont
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Signs it’s time to call us include:
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
- Old sand mastic that has cracked, crumbled or fallen out
Schools such as Sciennes Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Marchmont
Do you work for landlords with property near Edinburgh Waverley station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Does living near the coast affect sand mastic in Marchmont?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
What guarantee comes with the work?
Our 12-month guarantee covers every job, sand mastic included.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames generally get a flexible sealant.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
