Traditional burnt sand mastic around sash and case windows and doors in stone and brick in Cawdor, with a one-year guarantee on every job. Ask us for a quote.
- A silicone bead on a sash window that spoils the look
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sand mastic for homes and businesses in Cawdor
We work across Cawdor renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on tenement windows, stone surrounds and timber door frames, and people most often call us about window mastic to renew ahead of painting and draughty sash windows at the surround.
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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Cawdor: your questions answered
Can you help a landlord with a rental near Nairn station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Is Cawdor in your area for sand mastic?
Yes, Cawdor is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is the work guaranteed?
All our work has a 12-month guarantee.
How long will you be here?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we will say how long yours will take.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Crumbling stone or brickwork round the window
- Decayed frames that need repair
- Decisions on consent for listed homes
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- The type of sealant required
- The number and length of the joints
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
What we need to know
When you call or email, it’s useful to know:
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Aftercare tips
A little care helps the new joints last. Our advice:
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
- Renew mastic before redecorating the windows
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
