Sand mastic for homes and businesses in Crosshill
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on brick reveals, timber door frames and sash and case windows, and common reasons people get in touch are crumbling sand mastic round a window and mastic that needs renewing before redecorating.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. For a flat in Crosshill, access is the first thing to plan.
All of our work is guaranteed for twelve months, in Crosshill and everywhere else we cover.

Landlord and commercial work in Crosshill
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.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Clear gutters so water does not pour onto the windows
- Inspect the joints round the windows every year or so
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

Why it’s worth doing now in Crosshill
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Scottish rain finds any gap around a frame or wall joint, and in Crosshill, damp can spread through stone and plaster before anyone sees it.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.
What you get with us

Your questions about sand mastic in Crosshill
Who arranges sealant work on the shared parts of a tenement in Crosshill?
Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Windows often belong to the individual flat, but it’s worth checking your deeds.
Is Crosshill in your area for sand mastic?
Yes. Our work covers the whole of Scotland, and Crosshill is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you are set on DIY, put the effort into 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.
