How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. Outside jobs in Crawfordjohn need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

Glazing silicone in Crawfordjohn
Sealant on glazing does not last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. We work on glass balustrade bases, conservatory frames and glass-to-frame joints, and people most often call us about leaks from the base of a shower screen and leaking glazing joints on a rooflight.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Each job carries a 12-month guarantee, large or small.

Why it’s worth doing now in Crawfordjohn
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. In a place like Crawfordjohn, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

FAQs for Crawfordjohn
Is glazing silicone in Crawfordjohn guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Crawfordjohn for glazing silicone?
Yes. We work across all of Scotland, and Crawfordjohn is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Can landlords and businesses book you?
Yes, often. Several properties can go on one quote.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Run a squeegee over the glass when you are done
- Ventilate the conservatory to cut condensation
- Stick to mild cleaners on glass
- Check the gutters above the glazing for debris
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.

Do you need glazing silicone in Crawfordjohn?
Shower screen silicone gets wet every day. Mould grows into the bead and the edges begin to peel.

- A quick top-up bead that didn’t last
- Failed sealant around rooflight glass
- Glazing silicone that has cracked or come away
- Leaks where conservatory glass meets the frame
Around Crawfordjohn, as everywhere, glazing silicone is only as good as the preparation behind it.

Glazing silicone in Crawfordjohn: local notes
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as Crawfordjohn Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
