Glazing & conservatory sealant in Thankerton, South Lanarkshire
Glazing silicone across Thankerton and nearby, with old sealant always removed completely and a one-year guarantee.
- Drips on the inside of a conservatory window
- Split or lifting silicone on glass
- Leaks from the base of a shower screen
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Use gentle products around the joints
- Keep conservatory gutters clear of leaves
- Stick to mild cleaners on glass
- 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. Once it starts to peel, water gets behind it and the problem grows.
Glazing silicone in Thankerton
Glazing silicone is a maintenance item. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. We work on glass-to-frame joints, glass-to-glass joints and rooflights, and common reasons people get in touch are leaking glazing joints on a rooflight and water tracking down the inner face of the glass.
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.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How the job changes by surface
Glass-to-frame joints
We cut the old silicone from the glass without scratching it before new glazing silicone goes in.
Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Why it’s worth doing now in Thankerton
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes. In an older home around Thankerton, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Thankerton homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For landlords with property near Carstairs station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For an older house near a landmark such as Covington Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

How we quote for glazing silicone
We quote each job individually. These are the things that affect it:
- How easy the joints are to reach
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The product the joint needs
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.
What we need to know
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- A few photos by email, if you can
- The address or postcode of the job
- The problem you’ve noticed
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.
The process
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours, depending on how many joints need doing. Outdoor work around Thankerton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
