Sand mastic in Daldowie, done properly
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. We are often asked to deal with modern sealant on a period surround and wind and rain getting in round a sash window, on period & listed homes, stone surrounds and timber door frames.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Big or small, it’s backed by our one-year guarantee in Daldowie and across South Lanarkshire.

Looking after it afterwards
After the cure time, these simple habits help:
- Get any rot dealt with first
- Check with your local planning authority if your home is listed
- Look over the window mastic once a year
- Avoid heavy scraping on the mastic joint
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

What affects the cost of sand mastic
We don’t publish a price list. What we look at:
- Whether the work is at height
- How many areas need sealing
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What to tell us for a quote
When you contact us, these details help:
- Roughly how big the job is
- The problem you’ve noticed
- Where the job is, and your postcode
- A few photos by email, if you can
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What happens if it’s left?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Around Daldowie, 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.
Doing several joints on one visit usually makes better use of the time than several visits. We will give you a clear price for the lot.
What you get with us

- Approved under the ARBOMaster scheme

Advice
What the job involves on each surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Frames and glazing around Daldowie
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Daldowie 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.
Managing a site like Uddingston Grammar School? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Baillieston station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Daldowie questions
I let a flat near Baillieston station. Can you help?
Yes. We work for landlords and agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Is Daldowie within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How long will you be here?
Most jobs take a few hours per window, depending on the condition of the joints. Your quote will say how long we expect yours to take.
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.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
