About our sand mastic in Blackhall
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you have mastic round period door frames that has failed and old sand mastic that has cracked, crumbled or fallen out, we can help, on brick reveals, timber door frames and sash and case windows alike.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you’re in a tenement flat or a house in Blackhall, the joint between frame and wall is what keeps the weather out.
Every job comes with a one-year guarantee.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Windows and doors in Blackhall
Blackhall 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 older windows and doors, which can dry out and crack sooner where a building faces the weather. 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, often through a property factor. Who owns the windows depends on the title deeds.
Letting a property close to Haymarket station? Then any sash windows need sound mastic to keep draughts and rain out. Schools such as The Mary Erskine School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to St Columba's 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.

Quotes for sand mastic in Blackhall
We quote each job individually. This is what makes a difference:
- The size of the job
- Any mould that needs treating
- Which sealant suits the joint
- The old material and how stubborn it is
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
What to tell us for a quote
To make quoting easier, please include:
- Where the property is
- Roughly how big the job is
- If someone has resealed it before
- A few photos by email, if you can
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, email us at info@mrmastic.co.uk.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
- Keep sills and gutters clear so water drains away
- Avoid heavy scraping on the mastic joint
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Why it’s worth doing now in Blackhall
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. In a tenement flat in Blackhall, 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.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.

Different surfaces, different methods
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Timber door frames
Round a period front door, sand mastic gives the right look.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself generally 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 Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Blackhall, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work

FAQs for Blackhall
Does the coastal weather in Blackhall affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do you work for landlords with property near Haymarket station?
Yes. We work for letting agents and landlords as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job, sand mastic included.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Blackhall, along with the rest of our area.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we will tell you what to expect.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
