Brick reveals
Loose mastic comes out and deep gaps are packed before the new mastic goes in.
Sand mastic in Glenelg, done properly
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on brick reveals, sash and case windows and stone surrounds, and the jobs we see most are old cement repairs round a window that have failed and gaps between timber frames and stone or brick.
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.
Our work is backed for twelve months.

Frames and glazing around Glenelg
Glenelg is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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 Glenelg, as everywhere, sand mastic is only as good as the preparation behind it. For site and facilities teams at buildings such as Bernera School, larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Glenelg need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Keep children and pets away from the work area

Advice
How we quote for sand mastic
Call for a quick quote. What matters most is:
- When we can work, for business premises
- How easy the joints are to reach
- The number and length of the joints
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Any previous sealing or DIY work
- How we’d reach the joints
For sand mastic in Glenelg, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, 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.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Renew mastic before redecorating the windows
- Clear gutters so water doesn’t pour onto the windows
- Take care around the mastic when scraping paint
- Inspect the joints round the windows every year or so
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
Questions from Glenelg
Is Glenelg within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Glenelg any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Are you fully insured?
Yes. We are fully insured.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
