How we handle sand mastic in Netherburn
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. If you have mastic that needs renewing before redecorating and draughty sash windows at the surround, we can help, on period & listed homes, sash and case windows and timber door frames alike.
In and around a place like Netherburn, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

How to look after the new joints
Looking after new joints is easy:
- Have rotten timber repaired before new mastic goes in
- Ask the planning authority about consent for listed or conservation-area homes
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Your questions about sand mastic in Netherburn
I let a flat near Carluke station. Can you help?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Do you cover smaller places like Netherburn?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Is the work guaranteed?
Every job comes with our 12-month guarantee, and we are fully insured.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows. Somewhere like Netherburn may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Advice
What else we do in Netherburn
Why it’s worth doing now in Netherburn
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new work lasts. Around Netherburn, 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 normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Signs you need sand mastic in Netherburn
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
The most common problems we see are:
- Silicone on a period window that looks wrong
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
- Draughts and rain around sash boxes
If you let a flat or house near Carluke station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
