Glazing silicone for homes and businesses in Letham
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 leaks from the base of a shower screen and leaks where conservatory glass meets the frame, we can put it right, on rooflights, glass-to-glass joints and conservatory frames alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What happens if it’s left?
If the problem is a misted unit or a broken panel, sealant will not help. We will tell you that rather than seal it anyway and point you to a glazier or roofer. In a place like Letham, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into 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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
How the visit works

Your questions about glazing silicone in Letham
Will you come out to Letham?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do glazing silicone in Letham?
Yes, Letham is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Letham.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you reseal a frameless shower screen?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Don’t use a blade near the sealant
- Wipe the screen down after showering
- Keep conservatory gutters clear of leaves
- Act on drips or damp patches early
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.
Common problems we fix in Letham
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 running down inside the glass
- Water getting into a conservatory at the joints
- Stained, discoloured glazing silicone
- Failed joints on frameless glass
For an older house near a landmark such as Old Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- What guarantee comes with the work
- Whether you can choose the colour
- What insurance they hold
- When the joint can take water or movement
Landlord and commercial work in Letham
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Windows and doors in Letham
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 Letham, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
