Sand mastic in Drongan
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you are dealing with gaps where the frame meets the masonry and draughts and rain around sash boxes, we can help, on tenement windows, period & listed homes and sash and case windows alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Questions from Drongan
Do you cover Drongan for sand mastic?
Yes. We work across all of Scotland, and Drongan is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Is there a guarantee on sand mastic in Drongan?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames generally get a flexible sealant.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
What does sand mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours for a single window, longer for several. We’ll tell you when we quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Putty and glazing repairs
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Brick reveals
- Timber door frames
- Tenement windows

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Looking after it afterwards
After the cure time, these simple habits help:
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
- Renew mastic before redecorating the windows
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
What affects the cost of sand mastic
Call for a quick quote. The main things that affect it are:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Working hours on commercial sites
- The size of the job
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.
Asking for a quote
When you call or email, these details help:
- Whether it’s a home or a business
- The address or postcode of the job
- A few photos by email, if you can
- Any previous sealing or DIY work
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

Sand mastic in Drongan: local notes
Drongan is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Around Drongan, as everywhere, sand mastic is only as good as the preparation behind it. For jobs in and around Drongan, choosing the right material for each joint is as important as a tidy finish.

What happens on the day
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. The work generally takes a few hours per window, depending on the condition of the joints. Outside jobs in Drongan 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.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention any tricky access
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
