About our sand mastic in Greosabhagh
Across Greosabhagh, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. Typical jobs include weathered mastic on the most exposed windows and patchy fillers round a sash window, across sash and case windows, brick reveals and period & listed homes.
Outdoor sealant needs a dry surface, so window work around Greosabhagh is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
You’re covered for a year from the day we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Greosabhagh questions
Does living near the coast affect sand mastic in Greosabhagh?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Do you cover smaller places like Greosabhagh?
Yes. Greosabhagh is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
What does sand mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Are you fully insured?
Yes. Full insurance covers our work.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Common problems we fix in Greosabhagh
Some old mastic was never deep enough. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Draughty sash windows at the surround
- Old sand mastic that has cracked, crumbled or fallen out
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
Whether the job is in Greosabhagh itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- Are they insured?
- Whether VAT is included
- How the surfaces are prepared before sealing
- Which colour the sealant will be
Frames and glazing around Greosabhagh
Greosabhagh is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Around Greosabhagh, as everywhere, sand mastic is only as good as the preparation behind it.

When it is not the sealant

- Timber that has rotted
- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal

- The joint is raked out and cleaned.

Landlord and commercial work in Greosabhagh
If you manage several properties in or around Greosabhagh, several properties can go on one quote. Just tell us the addresses and what each one needs.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Can I do it myself?
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.
If you are 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 fails, we can still redo it.
Quotes for sand mastic in Greosabhagh
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- Working hours on commercial sites
- The product the joint needs
- Any mould that needs treating
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- The type of property
- Roughly how big the job is
- A few photos by email, if you can
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In a place like Greosabhagh, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
