Glazing silicone for homes and businesses in Dunning
Glass and frames expand and contract differently, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. Common call-outs are for leaking glazing joints on a rooflight and stained, discoloured glazing silicone, on glass-to-frame joints, glass-to-glass joints and shower screens.
In and around a place like Dunning, 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.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Your questions about glazing silicone in Dunning
What guarantee comes with glazing silicone in Dunning?
All our work, in Dunning and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you do glazing silicone in Dunning?
Yes. Our work covers the whole of Scotland, and Dunning is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Photos help us see what’s there when you send an email to info@mrmastic.co.uk.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Dunning, along with the rest of our area.
Are you fully insured?
Yes. Full insurance covers our work.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
How the job changes by surface
Shower screens
Silicone holds the water in on frameless screens. We renew it without marking the glass.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why it’s worth doing now in Dunning
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Around Dunning, water from a failed joint in an older stone home can soak into timber and plaster.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- We leave the area clean and tidy
- An ARBOMaster approved applicator
- White, clear, grey or coloured to suit, where the product allows
- We never seal over old sealant

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 few hours, depending on how many joints need doing. Outdoor work around Dunning depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

Frames and glazing around Dunning
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Homes close to St Serf's Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Common problems we fix in Dunning
The wrong sealant is a common cause. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
The most common problems we see are:
- Leaks from the base of a shower screen
- Sealant that was laid over old silicone and failed
- Failed joints on frameless glass
- Split or lifting silicone on glass
Around Dunning, as everywhere, glazing silicone is only as good as the preparation behind it.
