Nethermill Glazing Silicone
Glazing silicone across Nethermill and nearby, with every bit of old sealant taken out first.
- Cracked silicone between glass panels
- Failed sealant around rooflight glass
- Water escaping where a screen meets the wall
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the 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.
How we handle glazing silicone in Nethermill
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass before the new bead goes in. If you are dealing with water escaping where a screen meets the wall and water getting into a conservatory at the joints, we can help.
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.
You get a 12-month guarantee, the same in Nethermill as everywhere else we work.

Landlord and commercial work in Nethermill
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What happens if it’s left?
Replacing a conservatory roof is major work. If the leak is a failed sealant joint renewing the joint is the simpler fix. If it’s the roof itself, we’ll tell you. 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.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Why us?
- White, clear, grey or another colour, product permitting

How we quote for glazing silicone
For a quick quote, just ask. What matters most is:
- Mould in or behind the old joints
- Whether the work is at height
- The number and length of the joints
- The product the joint needs
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Helping us quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work and give you a clear quote.
How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Nethermill may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- 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.
Preparing for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
Getting a quote
Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job.

Common problems we fix in Nethermill
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
Any of these means the joints need attention:
- Water tracking down the inner face of the glass
- Conservatory leaks at frame and glazing joints
- New silicone smeared over old sealant
- Leaks from the base of a shower screen
Around Nethermill, as everywhere, glazing silicone is only as good as the preparation behind it.
Questions to ask before you book
- Is the old sealant removed completely?
- How the colour is chosen
- How long the guarantee is
- Whether VAT is included

Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Why not top up the existing silicone?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Nethermill.
Windows and doors in Nethermill
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with 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 jobs in and around Nethermill, choosing the right material for each joint is as important as a tidy finish.
