What affects the cost of glazing silicone
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- A few photos by email, if you can
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
If you’re in Biggar and need glazing silicone, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you’ll get a clear quote before any work starts.
Glazing silicone in Biggar
We renew glazing silicone on conservatories, 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. We work on shower screens, glass-to-glass joints and glass-to-frame joints, and common reasons people get in touch are leaks from the base of a shower screen and black or yellowed silicone on glass joints.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Other services in Biggar
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and letting agents in Biggar can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Questions from Biggar
Do you cover smaller places like Biggar?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with glazing silicone in Biggar?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
What sealant do you use on glazing?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
Do you fit new glass or sealed units?
That’s not something we do. A misted unit has failed inside and needs replacing by a glazier.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
When to call us in Biggar
Silicone won’t bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Any of these means the joints need attention:
- New silicone smeared over old sealant
- Silicone pulling away from the glass
- Black or yellowed silicone on glass joints
- Leaking glazing joints on a rooflight
In the older streets around Biggar Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens if it’s left?
You do not need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes, and we will tell you if that’s not the case. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.
What you get with us
- Neat joints and a tidy finish
- More than 20 years in sealant work
- ARBOMaster approved applicator
- Homes, businesses and hotels
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep conservatory gutters clear of leaves
- Do not leave a drip for the next storm
- Avoid strong solvents on or near the sealant
- Clean glass with a mild cleaner and a soft cloth
Avoid scraping near the new silicone when you clean. A soft cloth or sponge is best.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
Biggar homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Schools such as Biggar High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for most jobs in most cases. Outside jobs in Biggar need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
