Sand Mastic in Croftfoot
We cover Croftfoot for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Modern sealant on a period surround
- Draughty sash windows at the surround
- Gaps between timber frames and stone or brick
How we handle sand mastic in Croftfoot
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on tenement windows, sash and case windows and period & listed homes, and people most often call us about mastic worn away on windows facing the weather and old sand mastic that has cracked, crumbled or fallen out.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Croftfoot, and in a tenement the outside of the building may be a shared repair.
All our work is covered by a 12-month guarantee.

Croftfoot questions
How do repairs to the shared parts of a tenement in Croftfoot get organised?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
Is Croftfoot in your area for sand mastic?
Yes. We work across all of Scotland, and Croftfoot is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long does the job take?
Typically it takes a few hours per window, depending on the condition of the joints. Bigger jobs take longer.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
Are you fully insured?

What the job involves on each surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Windows and doors in Croftfoot
Historic houses like Provand's Lordship (about 3.4 miles north) are a reminder that the area around Croftfoot has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you look after a building such as St Margaret Mary's Secondary School, its window and door frames need their mastic kept sound, just like a home’s. Provand's Lordship, about 3.4 miles north, is one of the historic houses in the wider area around Croftfoot.

How it works
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a single window, longer for several. Inside a flat in Croftfoot, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints

What affects the quote in Croftfoot
For a quick quote, just ask. What matters most is:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- How many rooms, windows or areas are involved
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
When you call or email, it’s useful to know:
- A few pictures by email, if you can
- The type of property
- The problem you’ve noticed
- Any access issues, like height or stairs
Getting a quote is simple: let us know what needs doing and where. A few photos by email make the job easier to understand, and we will take it from there.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Sashes that need overhauling
- Rotten sashes, sills or window boxes (a joiner’s job)
- Whether work needs listed building consent
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Sash and case windows

What we are called out for in Croftfoot
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Keep an eye out for these signs:
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
- Gaps round a timber door in stone or brick
- Modern sealant on a period surround
Rented homes near Croftfoot station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY versus a professional finish
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
