About our sand mastic in Edgehead
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. If you’re dealing with mastic round period door frames that has failed and silicone on a period window that looks wrong, we can help.
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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of sand mastic
We do not publish a price list. What we look at:
- Access and height
- How many areas need sealing
- Working hours on commercial sites
- The size of the job
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- Where the property is
- The rough size of the job
- Whether it has been sealed before
We quote each job on its own. Simply send an email to info@mrmastic.co.uk and describe the job and send pictures if you have them.
Why deal with it now?
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What you get with us
- Fully insured
- Quality sealants from Arbo and Everbuild
- Anti-fungal sanitary silicone in wet areas
- We leave the area clean and tidy

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Do not paint over the new mastic
- Take care around the mastic when scraping paint
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
Landlord and commercial work in Edgehead
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
How the job changes by surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
DIY sealant or a professional job?
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.
If you are set on DIY, put the effort into 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.
Edgehead 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you look after a building such as Newbattle Community High School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Cranston Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Newtongrange station, any sash windows need sound mastic to keep draughts and rain out.

How it works
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours per window, depending on the condition of the joints. Outside jobs in Edgehead need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- 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.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
