Sand mastic for sash & case windows in Hazelbank, South Lanarkshire
We cover Hazelbank for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- A silicone bead on a sash window that spoils the look
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Around Hazelbank, 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.
Combining jobs into one visit is normally more efficient than separate visits. We will give you a clear quote for the lot.

About our sand mastic in Hazelbank
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and gaps round a timber door in stone or brick, we can put it right, on sash and case windows, stone surrounds and timber door frames alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Our work is backed for twelve months, in Hazelbank and everywhere else we cover.

Windows and doors in Hazelbank
Under the Repairing Standard, private landlords in Scotland have to keep homes 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.
Around Hazelbank, as everywhere, sand mastic is only as good as the preparation behind it. If you let a flat or house near Lanark station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Quotes for sand mastic in Hazelbank
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- The number and length of the joints
- Any working-time requirements on site
- Whether there’s mould to deal with
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. We give a clear quote before we start, so you know where you stand.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- A few pictures by email, if you can
There’s no standard price list. Instead, we give you a clear quote for your job. To get started, drop us a line at info@mrmastic.co.uk.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Do not run silicone over sand mastic
- Keep sills and gutters clear so water drains away
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
How it works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by checking each surround and agreeing the joints to renew.
- 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 mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Whether work needs listed building consent
- Masonry that needs repairing
- Timber that has rotted
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Surfaces we seal
- Period & listed homes
- Timber door frames
- Tenement windows
- Brick reveals
- Sash and case windows
- Stone surrounds
