How we handle sand mastic in Cranhill
We work across Cranhill renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. Common call-outs are for mastic round period door frames that has failed and silicone on a period window that looks wrong, on period & listed homes, tenement windows and sash and case windows.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. In Cranhill, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
You get a 12-month guarantee, the same in Cranhill as everywhere else we work.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured.
Different surfaces, different methods
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.
Aftercare tips
A little care helps the new joints last. We recommend:
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
- Get any rot dealt with first
- Clear gutters so water doesn’t pour onto the windows
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
What affects the quote in Cranhill
We don’t publish a price list, because jobs vary so much. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Access and height
- The product the joint needs
- The size of the job
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
What we need to know
Before you ask for a quote, have a think about:
- The type of property
- Photos by email, if that’s easy
- Where the property is
- Any previous sealing or DIY work
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To get started, drop us a line at info@mrmastic.co.uk.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Decisions on consent for listed homes
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Period & listed homes
- Sash and case windows
- Brick reveals
- Stone surrounds
- Timber door frames
- Tenement windows
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. For a tenement in Cranhill, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- First we agree which joints need doing.
- 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.
How to prepare
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What sand mastic looks like in Cranhill
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
For landlords with property near Carntyne station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as St Andrew's Secondary School, its window and door frames need their mastic kept sound, just like a home’s. Historic houses such as Provand's Lordship, about 2.6 miles west, show how far back building around Cranhill goes, and older homes nearby need a sealant that suits their walls.

Cranhill questions
How do repairs to the shared parts of a tenement in Cranhill get organised?
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, and we can quote for the factor or the owners directly.
Do you work for landlords with property near Carntyne station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
How do I get a quote for sand mastic in Cranhill?
