Glazing & conservatory sealant in Hoy, Orkney Islands
Specialist glazing silicone for Hoy: careful preparation, the right product and tidy work. Ask us for a quick quote.
- Rooflight joints letting water in
- Split or lifting silicone on glass
- Leaks where conservatory glass meets the frame
Keeping the joints in good condition
After the cure time, these simple habits help:
- Wipe the screen down after showering
- Get a new leak looked at quickly
- Check the gutters above the glazing for debris
- Inspect the sealant on glazing annually
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
About our glazing silicone in Hoy
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. We work on glass-to-frame joints, conservatory frames and rooflights, and common reasons people get in touch are shower screens leaking along the wall or tray and stained, discoloured glazing silicone.
In and around a place like Hoy, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
There’s a 12-month guarantee on every job, whatever its size.

When it is not the sealant

What we’re called out for in Hoy
The wrong sealant is a common cause. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
It’s worth asking for a quote if you see:
- Black or yellowed silicone on glass joints
- A quick top-up bead that didn’t last
- Failed joints on frameless glass
- Water escaping where a screen meets the wall
For jobs in and around Hoy, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- Is VAT in the price?
- Whether you can choose the colour
- What preparation is included
- Whether they seal over old material or remove it
Glazing silicone in Hoy: local notes
Hoy is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s 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 the more notice, the better.
In and around Hoy, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
Hoy is about 14 miles west of Kirkwall, in the Orkney Islands. Homes, rented property, offices and hotels in Hoy can book us for glazing silicone. The work is guaranteed for a year. Hoy is one of 51 places in the Orkney Islands we cover.
We work across the KW16 postcode area for glazing silicone and the streets around it. You’ll find Hoy on the B9049, so it’s easy for us to get to. We also cover Stromness (4 miles north), Cairston (5 miles north), Clestrain (5 miles north-east), Midland (5 miles east) and Clouston (6 miles north-east). If you are somewhere remote, a little more planning is needed.

The process
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours, depending on how many joints need doing. For a place like Hoy, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Advice
Also in Hoy
How the job changes by surface
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Shower screens
Mouldy or lifting sealant on a screen leaks. Cutting it out and resealing fixes it.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Hoy: your questions answered
Do you cover smaller places like Hoy?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Does the coastal weather in Hoy affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you guarantee glazing sealant work?
Our 12-month guarantee applies to every job we do.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
How long will you be here?
As a guide, most jobs take anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
