Sand mastic in Dumfries and Galloway: how it works

Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. We work on period & listed homes, brick reveals and timber door frames, and common reasons people get in touch are patchy fillers round a sash window and a silicone bead on a sash window that spoils the look.

At the end, we look at the finished work together. The visit itself normally takes a few hours for a single window, longer for several, depending on the size of the job.

We check each window surround and the condition of the joint.
The joint is raked out and cleaned.
We fill deep gaps so the new mastic isn’t too thick.
We point the joint with sand mastic by hand.
The finish is dressed neatly.

What you’ll pay

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Windows and doors across Dumfries and Galloway

Across Dumfries and Galloway, from Dumfries, Stranraer and Annan outwards, frames range from older timber to modern uPVC and aluminium. The mastic around all of them ages, and it’s normally the first thing to let the weather in.

Homes in Scotland come with their own details: sash and case windows, harled walls and, in the towns and cities, tenement flats. Dumfries and Galloway is part of the area we cover across Scotland. Dumfries and Galloway includes coastal places, where outside joints face more wind, rain and salt than they would inland. Walls facing the sea are usually the first to need attention.

Dumfries: For site and facilities teams at buildings such as Dumfries Academy, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Dumfries station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

Ask a joiner to look at soft timber first
Do not run silicone over sand mastic
Take care around the mastic when scraping paint
Inspect the joints round the windows every year or so

Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.

An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.

How we quote for sand mastic

There’s no set price list. What we look at:

Any mould that needs treating
The old material and how stubborn it is
Which sealant suits the joint
Access and height

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Asking for a quote

Photos help, but a description is a good start. Please mention:

Any previous sealing or DIY work
If it’s domestic, commercial or a hotel
Any access issues, like height or stairs
What’s wrong with the joints now

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, email us at info@mrmastic.co.uk.

Leave it or put it right?

Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them.

Questions to ask before you book

What guarantee comes with the work
Who turns up on the day
Whether all the old sealant comes out first
Which sealant they’ll use, and why

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

Sashes that rattle, stick or won’t open
Broken panes
Planning or listed building consent (your local planning authority decides)

Common questions in Dumfries and Galloway

Do you come to Dumfries and Galloway?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Dumfries and Galloway included.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Should I use sand mastic or silicone?

It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.

Is it possible to take out silicone and use sand mastic instead?

Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.

Can you match the sealant colour?

Most of the time, yes. We will explain which colours are available.

What information do you need?

A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
