What window mastic looks like in Dunollie
Dunollie is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
In the older streets around Christ Church Dunollie, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Oban High School, larger buildings have plenty of frames, and the mastic around each one ages.
Dunollie is about 1 mile north of Oban, in Argyll and Bute. Jobs in Dunollie get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Dunollie is one of 118 towns and villages in Argyll and Bute we cover for window mastic. There’s also a page for Glasgow, roughly 61 miles from Dunollie.

About our window mastic in Dunollie
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include hard, cracked sealant around windows and leaking joints at the ends of sills, on window sills, timber windows & doors and composite doors.
In and around a place like Dunollie, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All of our work is guaranteed for twelve months, in Dunollie and everywhere else we cover.

Common questions in Dunollie
Do you cover smaller places like Dunollie?
Yes, Dunollie is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Oban station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Can I add another job to the visit?
Yes. Just list everything you need.
Where do you work from?
Mr Mastic is based in Crawley. We cover Dunollie and the rest of Argyll and Bute, along with the rest of our area.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Do you need window mastic in Dunollie?
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Keep an eye out for any of the following:
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Rain getting in at the frame or under the sill
- White mastic on grey or black frames
Letting a property close to Oban station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a handful of frames, longer for a whole house. Outside jobs in Dunollie need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Different surfaces, different methods
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Why it’s worth doing now in Dunollie
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why book with us
- Old sealant always removed completely

When something else is needed
We will always be straight with you, so here’s what sealant can’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
