Glazing & conservatory sealant in Lilliesleaf, Scottish Borders
Glazing silicone for conservatories, rooflights, glass panels and shower screens for homes and businesses in Lilliesleaf and across the Scottish Borders. Fully insured, ARBOMaster approved and guaranteed for a year.
- Black or yellowed silicone on glass joints
- Water running down inside the glass
- Cracked silicone between glass panels
Different surfaces, different methods
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Glazing silicone in Lilliesleaf, done properly
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for sealant that was laid over old silicone and failed and shower screens leaking along the wall or tray, on rooflights, shower screens and conservatory frames.
Mastic can only go onto a dry joint, so outside work in Lilliesleaf depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Your job is guaranteed for a year, as with all our work.

What else we do in Lilliesleaf
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracked or broken glass
- Water coming through the roof rather than a sealant joint
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Conservatory frames
- Glass-to-frame joints
- Glass balustrade bases
- Glass-to-glass joints
- Shower screens
- Rooflights
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
How we quote for glazing silicone
There’s no set price list. The quote depends on:
- Any mould that needs treating
- The type of sealant required
- Working hours on commercial sites
- Whether the work is at height
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before work begins.
What we need to know
You do not need to know the technical terms. Just tell us:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
We quote each job on its own. Simply email us at info@mrmastic.co.uk and describe the job, and pictures are welcome.
Glazing silicone in Lilliesleaf: 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 failed outside joints work against that.
In and around Lilliesleaf, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

Questions from Lilliesleaf
What guarantee comes with glazing silicone in Lilliesleaf?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Lilliesleaf?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How much does glazing silicone cost in Lilliesleaf?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Is it enough to run a bead over the old sealant?
Silicone doesn’t stick to silicone and water gets between the layers. We cut out the old sealant first.
Leave it or put it right?
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old and water soon finds its way back. A proper reseal is the lasting answer. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

- A 12-month guarantee on all work

Signs you need glazing silicone in Lilliesleaf
The wrong sealant is a common cause. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
These are the problems we’re asked about most:
- Conservatory leaks at frame and glazing joints
- Split or lifting silicone on glass
- Drips on the inside of a conservatory window
- New silicone smeared over old sealant
Whether the job is in Lilliesleaf itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- How the joint is cleaned and prepared
- What insurance they hold
- Is VAT in the price?
- Whether the sealant suits the joint
What we do, step by step
On the day, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work usually takes a few hours, depending on how many joints need doing. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Keep children and pets away from the work area
