How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Window mastic in Auchengray, done properly
Around Auchengray we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you’re dealing with draughts coming in around windows and doors and old mastic that has gone black or come away, we can put it right.
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.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere like Auchengray may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Clear items away from the joints we’re working on

What affects the quote in Auchengray
The quote reflects the job in front of us. We take into account:
- The amount of work
- Any mould that needs treating
- The number of rooms or windows
- Any working-time requirements on site
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- How we’d reach the joints
- Photos by email, if that’s easy
Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand.
Honest limits
In fairness, there are a few things sealant will not fix:
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
- Broken hinges, locks or handles
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

Why act early in Auchengray
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. 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.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Window mastic in Auchengray: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Homes close to Auchengray Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Breich station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

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 work begins.
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. The old sealant has to come out completely.

Not normally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

No. We work neatly, protect the area around the joints and tidy up afterwards.
