Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Sand mastic in Kirriemuir, done properly
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for crumbling sand mastic round a window and old cement repairs round a window that have failed, on timber door frames, stone surrounds and sash and case windows.
Mastic can only go onto a dry joint, so outside work in Kirriemuir depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You get a one-year guarantee, the same in Kirriemuir as everywhere else we work.

Kirriemuir: your questions answered
What guarantee comes with sand mastic in Kirriemuir?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Kirriemuir in your area for sand mastic?
Yes, Kirriemuir is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Are you insured?
Yes, we are fully insured.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Why deal with it now?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Why us?
- Arbo and Everbuild products
- An ARBOMaster approved applicator
- Old sealant always removed completely
- More than 20 years in sealant work
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Sashes that need overhauling
- Whether work needs listed building consent
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Joints and surfaces we work on
- Stone surrounds
- Brick reveals
- Sash and case windows
- Timber door frames
- Period & listed homes
- Tenement windows
Keeping the joints in good condition
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t run silicone over sand mastic
- Renew mastic before redecorating the windows
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What we do, step by step
The work is kept neat and contained to the joints we’re treating. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. Outside jobs in Kirriemuir need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
