Sand mastic in Drumry
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and open joints round the window box, we can put it right, on stone surrounds, sash and case windows and tenement windows alike.
Outdoor sealant needs a dry surface, so window work around Drumry is planned around the weather. Let us know about access to every frame, including any upstairs.
Big or small, you get the same 12-month guarantee.

Do you need sand mastic in Drumry?
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
The problems people usually mention when they call are:
- Open joints round the window box
- Mastic round period door frames that has failed
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic worn away on windows facing the weather
If you look after a building such as Saint Andrew's High School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking

Drumry questions
Do you cover smaller places like Drumry?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Drumry station?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll advise.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
How to look after the new joints
After the cure time, these simple habits help:
- Keep sills and gutters clear so water drains away
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
- Plan mastic work ahead of painting
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right 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.

What affects the cost of sand mastic
There’s no set price list, because no two jobs are the same. What we look at:
- How easy the joints are to reach
- How many areas need sealing
- When we can work, for business premises
- Which sealant suits the joint
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

What the job involves on each surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
How the visit works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to a full day, depending on how many windows. Outdoor work around Drumry depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

Related advice
Why it’s worth doing now in Drumry
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

- One-year guarantee on every job

Sand mastic in Drumry: local notes
Drumry is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Letting a property close to Drumry station? Then any sash windows need sound mastic to keep draughts and rain out.
