Sand mastic for homes and businesses in Smailholm
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. Common call-outs are for weathered mastic on the most exposed windows and patchy fillers round a sash window, across period & listed homes, timber door frames and brick reveals.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You get a one-year guarantee, the same in Smailholm as everywhere else we work.

How the job changes by surface
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes anything from a few hours to a full day, depending on how many windows. Around Smailholm, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

What sand mastic looks like in Smailholm
Sash and case windows are common in older Scottish homes, 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 sound outside sealant is part of that.
For an older house near a landmark such as Smailholm Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens if it’s left?
Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. In a place like Smailholm, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Is there a guarantee on sand mastic in Smailholm?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Which products do you use?

Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
How do I get a quote for sand mastic in Smailholm?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
When to call us in Smailholm
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they usually need raking out.
If you can see any of these, it’s time to have the joints looked at:
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
- Failed mastic on an exposed elevation
- Cracked mastic round a front door frame
Around Smailholm, as everywhere, sand mastic is only as good as the preparation behind it.
