How we handle sand mastic in Candy Mill
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you’re dealing with mastic dropping out of the joint and failed mastic on an exposed elevation, we can help, whatever the surface.
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.
There’s a 12-month guarantee on every job.

Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. 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.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Do you need sand mastic in Candy Mill?
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
These are the problems we are asked about most:
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
- Cement or filler used on old window joints that has cracked
- Mastic worn away on windows facing the weather
For jobs in and around Candy Mill, choosing the right material for each joint is as important as a tidy finish.
What to look for in a quote

- Is VAT in the price?
- Whether all the old sealant comes out first
- When the joint can take water or movement
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
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 sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Windows and doors in Candy Mill
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Candy Mill, as everywhere, sand mastic is only as good as the preparation behind it.

Do you cover Candy Mill for sand mastic?
Yes. We work across all of Scotland, and Candy Mill is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.

Not straight away. The skin forms first, and the full set comes later, and we will tell you what to expect.

Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
