Glazing Silicone in Harray
Glazing silicone across Harray and nearby, with old sealant always removed completely and a 12-month guarantee.
- Leaking glazing joints on a rooflight
- Drips on the inside of a conservatory window
- Failed joints on frameless glass
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check the gutters above the glazing for debris
- Keep harsh solvents off the silicone
- Open vents or windows to let moisture out
- Look over the glazing joints once a year
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.
How we handle glazing silicone in Harray
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame and reseal the joint. We’re often asked to deal with leaking glazing joints on a rooflight and a quick top-up bead that didn’t last, across conservatory frames, glass-to-glass joints and shower screens.
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.
Whatever the size of the job, you get the same one-year guarantee.

What happens if it’s left?
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone and water soon finds its way back. A proper reseal is the lasting answer. Around Harray, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

When to call us in Harray
Shower screen silicone gets wet every day. Mould gets into it and the edges begin to peel.
Keep an eye out for these signs:
- Shower screens leaking along the wall or tray
- Silicone pulling away from the glass
- Black or yellowed silicone on glass joints
- New silicone smeared over old sealant
Around Harray, as everywhere, glazing silicone is only as good as the preparation behind it.

What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours, depending on how many joints need doing. Outdoor work around Harray 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.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

Windows and doors in Harray
Harray is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on glazing joints and frame seals, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
In the older streets around Grimeston Congregational Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Harray is about 9 miles north-west of Kirkwall, in the Orkney Islands. We carry out glazing silicone for homes and businesses in Harray and the surrounding area, as part of our work across the Orkney Islands. Harray is one of 51 towns and villages in the Orkney Islands where we work.
Every address in KW17 is covered for glazing silicone. Nearby, we also carry out glazing silicone in Bimbister (1 mile south), Russland (1 mile west), Grimeston (2 miles south), Hourston (2 miles north-west) and Wasbister (3 miles south-west). Island and remote addresses take a little more planning, so please mention your location when you email us at info@mrmastic.co.uk.

Common questions in Harray
Does living near the coast affect glazing silicone in Harray?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Harray?
Yes. Harray is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Do you have insurance?
Yes. We are fully insured.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Which silicone is used for glass joints?
We use a neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Harray, along with the rest of our area.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
