Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
About our glazing silicone in St Leonard's
We don’t replace glass, and misting between panes means a failed sealed unit. Our work is the sealant joints and that’s often where the water gets in. We work on shower screens, glass balustrade bases and glass-to-frame joints, and the jobs we see most are cracked silicone between glass panels and conservatory leaks at frame and glazing joints.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you are in a tenement flat or a house in St Leonard's, the joint between frame and wall is what keeps the weather out.
All of our work is guaranteed for twelve months, in St Leonard's and everywhere else we cover.

What we’re called out for in St Leonard's
Silicone will not bond to a dirty surface. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Most people get in touch when they notice something like this:
- Water escaping where a screen meets the wall
- Conservatory leaks at frame and glazing joints
- Stained, discoloured glazing silicone
- Rooflight joints letting water in
If you let a flat or house near Edinburgh Waverley station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Questions to ask before booking
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
- How hidden problems are handled
- Whether VAT is included
For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
St Leonard's homes and the weather
St Leonard's is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on glazing joints and frame seals, especially on the side facing the sea. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls.
Historic houses such as Whitefoord House, about 0.9 miles north, show how far back building around St Leonard's goes, and older homes nearby need a sealant that suits their walls. Managing a site like St Trinnean's School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in St Leonard's
How is work on the outside of a tenement in St Leonard's usually arranged?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Is glazing silicone in a coastal place like St Leonard's any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Is it possible to redo the silicone on a shower screen?
We can. The old bead comes off without marking the glass before cleaning and resealing.
Can you just put new silicone over the old?
A top-up rarely holds. The new bead cannot grip the old one so we take it all out and start clean.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Use a gentle glass cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
- Open vents or windows to let moisture out
- Inspect the sealant on glazing annually
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.
