About our sand mastic in Wanlockhead
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Common call-outs are for mastic that needs renewing before redecorating and open joints round the window box, across stone surrounds, period & listed homes and sash and case windows.
In and around a place like Wanlockhead, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

The process
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a single window, longer for several. Somewhere like Wanlockhead 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.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Related advice
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Wanlockhead: your questions answered
Is Wanlockhead within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on sand mastic in Wanlockhead?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How do I get a quote for sand mastic in Wanlockhead?
Size, access and the old material all affect the cost. Ask us for a quote.
Is sand mastic better than silicone for my windows?
We will help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later and we will give you an idea for your job.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.

Sand mastic in Wanlockhead: local notes
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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as Wanlockhead Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Inspect the joints round the windows every year or so
- Avoid patching sand mastic with silicone
- Plan mastic work ahead of painting
- Check with your local planning authority if your home is listed
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
When to call us in Wanlockhead
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
It’s worth asking for a quote if you see:
- Window mastic to renew ahead of painting
- Cracked mastic round a front door frame
- Modern sealant on a period surround
- Open joints round the window box
Around Wanlockhead, as everywhere, sand mastic is only as good as the preparation behind it.

How the job changes by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Stone surrounds
The stone is treated with care while raking out the old mastic.
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Wanlockhead, 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
