Window mastic in Belhelvie
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. Common call-outs are for draughts coming in around windows and doors and gaps between the frame and the inside reveal, across window sills, aluminium frames and patio & French doors.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. For a place like Belhelvie, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Windows and doors in Belhelvie
Belhelvie is within about 3 miles of 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 window and door frames, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Homes close to Belhelvie North Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Dyce station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why act early in Belhelvie
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a place like Belhelvie, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

When it isn’t the sealant
In fairness, some problems need a different trade:
- Faulty window hardware
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)

Belhelvie questions
Is Belhelvie within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Dyce station. Can you help?
Yes, we work for landlords and letting agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What does window mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk and let us know what needs doing and where.
Should I try DIY first?
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.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Keeping the joints in good condition
Looking after new joints is easy:
- Wash the frames with mild soapy water
- Do not use solvent cleaners on the joint
- Keep jet washers away from the mastic
- Don’t paint over the silicone
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
