How we handle sand mastic in Milnathort
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on brick reveals, timber door frames and tenement windows, and the jobs we see most are gaps where the frame meets the masonry and old sand mastic that has cracked, crumbled or fallen out.
Outdoor sealant needs a dry surface, so window work around Milnathort is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, you get the same 12-month guarantee in Milnathort and across Perth and Kinross.

Do you need sand mastic in Milnathort?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Common reasons people contact us include:
- Old sand mastic that has cracked, crumbled or fallen out
- Window mastic to renew ahead of painting
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
Schools such as Kinross High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Leave the new mastic unpainted
- Plan mastic work ahead of painting
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Advice
Questions from Milnathort
Can you do sand mastic in Milnathort?
Yes. Our work covers the whole of Scotland, and Milnathort is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
What guarantee comes with sand mastic in Milnathort?
All our work, in Milnathort and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Milnathort homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near Parish Church and Churchyard, the joint between an old wall and a newer frame is usually the first place rain gets in.
