Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Sand mastic for homes and businesses in Lownie Moor
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. Typical jobs include crumbling sand mastic round a window and gaps where the frame meets the masonry, across brick reveals, stone surrounds and sash and case windows.
Mastic can only go onto a dry joint, so outside work in Lownie Moor depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Big or small, it’s backed by our 12-month guarantee in Lownie Moor and across Angus.

How the job changes by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Common problems we fix in Lownie Moor
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.

Advice
Quotes for sand mastic in Lownie Moor
Your quote is based on your job. We take into account:
- When we can work, for business premises
- How easy the joints are to reach
- Whether there’s mould to deal with
- The size of the job
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What we need to know
When you call or email, it’s useful to know:
- The address or postcode of the job
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
- Roughly how big the job is
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.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Have rotten timber repaired before new mastic goes in
- Keep modern sealant off the mastic
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together.

How do I get a quote for sand mastic in Lownie Moor?
Every job is different, so each one gets its own quote. To get one, drop us a line at info@mrmastic.co.uk with a short description of the job.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Sand mastic in Lownie Moor: local notes
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.
Whether the job is in Lownie Moor itself or nearby, the right material for each joint matters as much as a neat finish.
