DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
About our sand mastic in Coupar Angus
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We’re often asked to deal with failed mastic on an exposed elevation and cement or filler used on old window joints that has cracked, across timber door frames, period & listed homes and sash and case windows.
Outdoor sealant needs a dry surface, so window work around Coupar Angus is planned around the weather. Let us know about access to every frame, including any upstairs.
Every job is covered by our 12-month guarantee, wherever you are in Perth and Kinross.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Find out about consent before window work on a listed home
- Clear gutters so water doesn’t pour onto the windows
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Frames and glazing around Coupar Angus
Sash and case windows are common in older Scottish homes, 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.
In and around Coupar Angus, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. Historic houses such as Balhary House, about 4.9 miles north-east, show how far back building around Coupar Angus goes, and older homes nearby need a sealant that suits their walls.

What else we do in Coupar Angus
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Sash cords, weights and draught-proofing of the sashes
- Decisions on consent for listed homes
- Timber that has rotted
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
Joints and surfaces we work on
- Brick reveals
- Sash and case windows
- Tenement windows
- Stone surrounds
- Period & listed homes
- Timber door frames
What happens if it’s left?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. 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.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Coupar Angus: your questions answered
Is Coupar Angus in your area for sand mastic?
Yes. Our work covers the whole of Scotland, and Coupar Angus is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Is sand mastic in Coupar Angus guaranteed?
All our work, in Coupar Angus and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How much does sand mastic cost in Coupar Angus?
Size, access and the old material all affect the cost. Ask us for a quote.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
How it works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a single window, longer for several. Around Coupar Angus, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
