How we handle sand mastic in Ashkirk
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on timber door frames, stone surrounds and tenement windows, and common reasons people get in touch are open joints round the window box and old cement repairs round a window that have failed.
In and around a place like Ashkirk, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours for a single window, longer for several. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not 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.
How to prepare
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Ashkirk homes and the weather
Historic houses like Bowhill House (about 4.4 miles north-west) are a reminder that the area around Ashkirk has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you live in an older home near Ashkirk Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. In and around Ashkirk, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Ashkirk: your questions answered
Do you cover Ashkirk for sand mastic?
Yes, Ashkirk is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Is there a guarantee on sand mastic in Ashkirk?
All our work, in Ashkirk and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
When will the new mastic be hard?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

- Damaged stone surrounds

What affects the quote in Ashkirk
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- How many areas need sealing
- Whether there’s mould to deal with
- The product the joint needs
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.
What we need to know
When you contact us, these details help:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- How we’d reach the joints
- Photos by email, if that is easy
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Aftercare tips
After the cure time, these simple habits help:
- Do not run silicone over sand mastic
- Ask us before painting near the mastic
- Clear gutters so water doesn’t pour onto the windows
- Check the mastic when you check the paintwork
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs 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. All the old material has to come out first.
For landlords and businesses
Landlords and agents in Ashkirk can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

What the job involves on each surface
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
