Sand mastic in Westerwood
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include wind and rain getting in round a sash window and gaps where the frame meets the masonry, on timber door frames, tenement windows and brick reveals.
In and around a place like Westerwood, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All our work is covered by a 12-month guarantee, wherever you are in North Lanarkshire.

Different surfaces, different methods
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Westerwood: your questions answered
I let a flat near Cumbernauld station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is Westerwood in your area for sand mastic?
Yes. We work across all of Scotland, and Westerwood is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Is the work guaranteed?
You get our one-year guarantee to all our work.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
What affects the quote in Westerwood
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Working hours on commercial sites
- Any mould that needs treating
- The size of the job
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, send an email to info@mrmastic.co.uk.
Why it’s worth doing now in Westerwood
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. 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.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
- Sort the mastic before the decorators arrive
- Get any rot dealt with first
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
The process
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several, and we explain the cure time before we leave. Somewhere like Westerwood may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Westerwood homes and the weather
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Letting a property close to Cumbernauld station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
