Window mastic in Barcaldine
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. If you are dealing with draughts coming in around windows and doors and water coming in at the bottom corners of a door, we can put it right, on patio & French doors, composite doors and timber windows & doors alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

When to call us in Barcaldine
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
These are the problems we’re asked about most:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- A bead that doesn’t match the frame
- Gaps where the sill meets the wall
Whether the job is in Barcaldine itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- How long to leave it before use
- Is VAT in the price?
- How much experience the applicator has
- How the surfaces are prepared before sealing
Window mastic in Barcaldine: local notes
Barcaldine is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Barcaldine is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
Around Barcaldine, as everywhere, window mastic is only as good as the preparation behind it.

Questions from Barcaldine
Can you do window mastic in Barcaldine?
Yes, Barcaldine is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Do you cover smaller places like Barcaldine?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
How much does window mastic cost in Barcaldine?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How long does it take to reseal the windows on a house?
A few frames take a few hours. We confirm the timing with your quote.
What should I tell you?
Tell us what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid harsh chemicals near the mastic
- Ventilate rooms so frames don’t stay wet inside
- Look round the frames every year or so
- Clean frames with a soft cloth and soapy water
Most silicone sealants will not take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a morning for a couple of windows and a door. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- 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.
Before we arrive
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
