Quotes for glazing silicone in Thornhill
The price is agreed before any work begins. It takes into account:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove

The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear quote before any work starts.

Glazing silicone for homes and businesses in Thornhill
A frameless shower screen depends on its silicone. Leaks normally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. If you have stained, discoloured glazing silicone and water running down inside the glass, we can help, on glass-to-glass joints, glass balustrade bases and shower screens alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Questions from Thornhill
Do you cover Thornhill for glazing silicone?
Yes. Our work covers the whole of Scotland, and Thornhill is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
What guarantee comes with glazing silicone in Thornhill?
All our work, in Thornhill and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you seal glass balustrade bases?
We can, if the base joint is sealed. Photos help us see what’s there when you email us at info@mrmastic.co.uk.
How long does glazing silicone take?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job, including preparation and clearing up. We’ll confirm how long when we quote.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most jobs. Around Thornhill, distance and access matter more than parking. 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.
- We cut out the failed silicone, taking care of the glass and frame.
- 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.
Before we arrive
- Tell us if parking is tricky
- Mention any tricky access
- Tell us about any water getting in

Advice
Frames and glazing around Thornhill
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. The west of Scotland is wetter than the east, which means glazing joints and frame seals has to cope with a lot of rain.
Around Thornhill, as everywhere, glazing silicone is only as good as the preparation behind it. For jobs in and around Thornhill, choosing the right material for each joint is as important as a tidy finish.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Stick to mild cleaners on glass
- Open vents or windows to let moisture out
- Clear the conservatory gutters regularly
- Squeegee the shower screen after each use
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part, and we’ll tell you which.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Other services in Thornhill
Leave it or put it right?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

Different surfaces, different methods
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
Rooflights
Rooflights get the full force of the weather. Its sealant ages faster than vertical joints.
