About our sand mastic in Westruther
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We work on brick reveals, tenement windows and stone surrounds, and the jobs we see most are mastic dropping out of the joint and window mastic to renew ahead of painting.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Our work is backed for twelve months, in Westruther and everywhere else we cover.

Quotes for sand mastic in Westruther
For a quick quote, just ask. The main things that affect it are:

- Whether old sealant or filler has to be cut out

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints. Around Westruther, 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.
- We remove the old, loose mastic.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property

Related advice
Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Westruther, water from a failed joint in an older stone home can soak into timber and plaster.
A few things move the cost up or down: 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.

Questions from Westruther
Will you come out to Westruther?
Yes. Westruther is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee on sand mastic in Westruther?
All our work, in Westruther and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will advise.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Different surfaces, different methods
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is normally favoured.
Windows and doors in Westruther
Many older homes in Scotland have sash and case windows, 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.
Around Westruther, as everywhere, sand mastic is only as good as the preparation behind it. Homes close to Old Parish Church and Churchyard include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Look over the window mastic once a year
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
- Take care around the mastic when scraping paint
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
