Duddingston Glazing Silicone
Our applicators work in Duddingston on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old material cut out, joints cleaned and sealed neatly.
- Conservatory leaks at frame and glazing joints
- Mouldy sealant around glass panels
- Failed sealant around rooflight glass
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Do not use a blade near the sealant
- Stick to mild cleaners on glass
- Act on drips or damp patches early
- Use gentle products around the joints
Gentle products are best near the sealant. Strong solvents can soften or mark it.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.
How we handle glazing silicone in Duddingston
Glass replacement is not something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. If you have conservatory leaks at frame and glazing joints and split or lifting silicone on glass, we can help, whatever the surface.
In and around a place like Duddingston, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
Every job is covered by a 12-month guarantee, wherever you are in Edinburgh.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on how many joints need doing, including the tidy-up. Somewhere like Duddingston may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

How the job changes by surface
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
Duddingston homes and the weather
Duddingston is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. 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.
If you look after a building such as Holy Rood High School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Duddingston Kirk, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Duddingston is about 1 mile south-west of South Portobello, in Edinburgh.

Common problems we fix in Duddingston
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
These are the problems we are asked about most:
- Black or yellowed silicone on glass joints
- Silicone pulling away from the glass
- Water tracking down the inner face of the glass
- A quick top-up bead that didn’t last
For landlords with property near Brunstane station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A roof that has moved or dropped
- Water coming through the roof rather than a sealant joint
- A sealed unit that has misted inside
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Glass balustrade bases
- Conservatory frames
- Glass-to-frame joints
- Shower screens
- Glass-to-glass joints
- Rooflights
Can I do it myself?
If you’re 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 fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

Questions from Duddingston
Do you work for landlords with property near Brunstane station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Does living near the coast affect glazing silicone in Duddingston?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Where are you based?
We work from Crawley. Our applicators cover Duddingston.
Is it possible to redo the silicone on a shower screen?
Yes, it’s a common job. We use anti-fungal silicone suited to bathrooms.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Do you guarantee glazing sealant work?
Our 12-month guarantee applies to every job we do.
Can a conservatory leak be sealed?
If the water is coming in through failed sealant joints, yes. If the cause is the roof, a panel or a unit, we will say so.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Why it’s worth doing now in Duddingston
Resealing can’t fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. In a place like Duddingston, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
