Tenement and terrace windows

Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
How we handle sand mastic in Udny Green
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include failed mastic on an exposed elevation and modern sealant on a period surround, on tenement windows, period & listed homes and timber door frames.
In and around a place like Udny Green, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Every job is covered by our one-year guarantee.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Outdoor work around Udny Green depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Windows and doors in Udny Green
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as Christ's Kirk Of Udny, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Udny Green is about 7 miles east of Inverurie, in Aberdeenshire. Wherever you are in the AB41 postcode area, we can carry out sand mastic at your property. Across Aberdeenshire, we cover 161 places, Udny Green among them. For nearby work, see our Aberdeen page.

What happens if it’s left?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Around Udny Green, 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.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

FAQs for Udny Green
What guarantee comes with sand mastic in Udny Green?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Udny Green for sand mastic?
Yes, Udny Green is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Where do you work from?
Mr Mastic is based in Crawley. We cover Udny Green and the rest of Aberdeenshire, along with the rest of our area.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
How much does sand mastic cost in Udny Green?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Common problems we fix in Udny Green
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber and we normally remove them.
These are the problems we’re asked about most:
- Weathered mastic on the most exposed windows
- Gaps where the frame meets the masonry
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
Around Udny Green, as everywhere, sand mastic is only as good as the preparation behind it.
Before you book anyone
- Is the old sealant removed completely?
- Is VAT in the price?
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
