How we handle window mastic in Auchinraith
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you’re dealing with cracked sealant at the sill ends and rushed sealant from a window installation, we can help, on uPVC windows, patio & French doors and aluminium frames alike.
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.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Do you need window mastic in Auchinraith?
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that has split away from the wall
- Mastic that’s falling out in pieces
- A bead that does not match the frame
- Water coming in at the bottom corners of a door
If you let a flat or house near Blantyre station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Your questions about window mastic in Auchinraith
Do you cover Auchinraith for window mastic?
Yes. We work across all of Scotland, and Auchinraith is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you cover smaller places like Auchinraith?
Yes, Auchinraith is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Is the work guaranteed?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Leave it or put it right?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Make sure the drainage slots are not blocked
- Avoid blasting the frames with a pressure washer
- Do not use solvent cleaners on the joint
- Look round the frames every year or so
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
When something else is needed
A few problems are outside what sealant work can do:
- Faulty window hardware
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.

The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Outside jobs in Auchinraith need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
