Sand mastic in Gartness
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Typical jobs include a silicone bead on a sash window that spoils the look and mastic that needs renewing before redecorating, on timber door frames, brick reveals and tenement windows.
Mastic can only go onto a dry joint, so outside work in Gartness depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Big or small, you get the same one-year guarantee in Gartness and across North Lanarkshire.

Looking after it afterwards
To keep the joints looking good and working properly:
- Clear gutters so water doesn’t pour onto the windows
- Renew mastic before redecorating the windows
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

Check with your local planning authority. They decide whether consent is needed for work to your windows.
Why it’s worth doing now in Gartness
If you’re redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Gartness homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. 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.
Schools such as Airdrie Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Drumgelloch station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Gartness is about 1 mile south-east of Airdrie, in North Lanarkshire. Gartness gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

What affects the quote in Gartness
We do not publish a price list. The quote depends on:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- How easy the joints are to reach
- The product the joint needs
We don’t 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 and we’ll talk you through it.

What the job involves on each surface
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Stone surrounds
The stone is treated with care while raking out the old mastic.
What we do, step by step
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a single window, longer for several. Around Gartness, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- Move anything stored near the joints
