Sand mastic in Clermiston, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include gaps where the frame meets the masonry and silicone on a period window that looks wrong, on brick reveals, timber door frames and stone surrounds.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Clermiston, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
Whatever the size of the job, you get the same 12-month guarantee.

What we can’t put right
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Planning or listed building consent (your local planning authority decides)
- Sashes that need overhauling
- Putty and glazing repairs
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Brick reveals
- Stone surrounds
- Timber door frames

- Period & listed homes
- Sash and case windows
What affects the quote in Clermiston
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- The size of the job
- The product the joint needs
- The number of rooms or windows
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- If someone has resealed it before
- Whether it’s a home or a business
- Photos by email, if that is easy
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear quote.
What happens if it’s left?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a tenement flat in Clermiston, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Why us?
- We leave the area clean and tidy
- Fully insured
- 12-month guarantee on every job

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Clermiston, tell us the floor, how the door entry system works and where we can park nearby.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

When to call us in Clermiston
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Old cement repairs round a window that have failed
- Gaps where the frame meets the masonry
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
Caroline Park, about 2.7 miles north-east, is one of the historic houses in the wider area around Clermiston.

Frames and glazing around Clermiston
Clermiston is within about 2 miles of 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. 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. Who owns the windows depends on the title deeds.
Letting a property close to South Gyle station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Craigmount High School, its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Clermiston
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Inspect the joints round the windows every year or so
- Avoid patching sand mastic with silicone
- Avoid heavy scraping on the mastic joint
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
