Fintry questions
Can you do sand mastic in Fintry?
Yes. We work across all of Scotland, and Fintry is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Is Fintry within the area you cover?
Yes, Fintry is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
What information do you need?
Let us know what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
How long will you be here?
Most jobs take a few hours for a single window, longer for several. Your quote will say how long we expect yours to take.
Sand mastic for homes and businesses in Fintry
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you have weathered mastic on the most exposed windows and draughts and rain around sash boxes, we can put it right, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Fintry depends on the weather. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Landlords, agents and businesses in Fintry
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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, then guaranteed for a year.
What affects the cost of sand mastic
You will get a clear quote before we start. It takes into account:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The size of the job
- Whether there’s mould to deal with
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What to tell us for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Where the job is, and your postcode
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To get started, send an email to info@mrmastic.co.uk.
Windows and doors in Fintry
The west of Scotland 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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For an older house near a landmark such as Old Fintry Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why it’s worth doing now in Fintry
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In a place like Fintry, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
When to call us in Fintry
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint and we normally remove them.
Common reasons people contact us are:
- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
- Mastic dropping out of the joint
Around Fintry, as everywhere, sand mastic is only as good as the preparation behind it.
