About our sand mastic in Greenhills
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, brick reveals and timber door frames, and common reasons people get in touch are mastic round period door frames that has failed and cement or filler used on old window joints that has cracked.
In and around a place like Greenhills, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
You get a 12-month guarantee, the same in Greenhills as everywhere else we work.

Greenhills questions
Can you help a landlord with a rental near East Kilbride station?
Yes. We work for landlords and agents as well as householders. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you cover smaller places like Greenhills?
Yes. Greenhills is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is the work guaranteed?
There’s a 12-month guarantee on every job, sand mastic included.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours for a single window, longer for several. We’ll tell you when we quote.
Landlords, agents and businesses in Greenhills
For anyone letting property in or around Greenhills, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Leave it or put it right?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Around Greenhills, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

What we’re called out for in Greenhills
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
These are the problems we’re asked about most:
- Modern sealant on a period surround
- Cracked mastic round a front door frame
- Gaps between timber frames and stone or brick
- Draughts and rain around sash boxes
Managing a site like Duncanrig Secondary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What sand mastic looks like in Greenhills
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Greenhills is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
If you let a flat or house near East Kilbride station, any sash windows need sound mastic to keep draughts and rain out.

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. Outside jobs in Greenhills need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
How to get a quote

Aftercare tips
So the new joints stay in good condition:
- Ask us before painting near the mastic
- Go gently near the mastic when preparing windows
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
