About our sand mastic in Douglastown
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you’re dealing with tired mastic found when preparing windows for paint and open joints round the window box, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Big or small, it’s backed by our one-year guarantee.

Douglastown: your questions answered
Is Douglastown within the area you cover?
Yes, Douglastown is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on sand mastic in Douglastown?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you match the sealant colour?
We will 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.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
How much does sand mastic cost in Douglastown?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later and we’ll give you an idea for your job.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Douglastown homes and the weather
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. Historic houses like Glamis Castle (about 2 miles west) are a reminder that the area around Douglastown has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Historic houses such as Glamis Castle, about 2 miles west, show how far back building around Douglastown goes, and older homes nearby need a sealant that suits their walls.

What sealant work can’t fix
A few problems are outside what sealant work can do:

If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Check with your local planning authority if your home is listed
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

What happens if it’s left?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. In a place like Douglastown, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. Outdoor work around Douglastown depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Mention any parking rules near the property

Related advice
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas 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. Everything old must be removed first.
What we are called out for in Douglastown
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
The most common problems we see are:
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
- Silicone on a period window that looks wrong
- Cement or filler used on old window joints that has cracked
In and around Douglastown, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
