Sand mastic for homes and businesses in Cornhill
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. Typical jobs include crumbling sand mastic round a window and cracked mastic round a front door frame, across period & listed homes, sash and case windows and timber door frames.
In and around a place like Cornhill, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.

Cornhill homes and the weather
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.
In and around Cornhill, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Questions from Cornhill
Do you cover Cornhill for sand mastic?
Yes. We work across all of Scotland, and Cornhill is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Is Cornhill within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
When will the new mastic be hard?
Not right away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Outdoor work around Cornhill depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

Why act early in Cornhill
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a place like Cornhill, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why Cornhill clients choose us
- An ARBOMaster approved applicator
- Experience in homes, commercial sites and hotels
- 180+ five-star Google reviews
- More than 20 years in sealant work
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. 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.

Signs you need sand mastic in Cornhill
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
People usually contact us when they notice something like this:
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
Homes close to Ordiquhill And Cornhill Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- How the surfaces are prepared before sealing
- What product goes in the joint
- What happens if they find a problem under the old sealant
- Is VAT in the price?
