Glazing silicone in Newhaven
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that’s often where the water gets in. If you are dealing with sealant that was laid over old silicone and failed and conservatory leaks at frame and glazing joints, we can put it right, on glass-to-glass joints, glass balustrade bases and rooflights alike.
Newhaven is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
Big or small, it’s backed by our one-year guarantee.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Surface by surface
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
Questions from Newhaven
I let a flat near Edinburgh Waverley station. Can you help?
Yes, we work for letting agents and landlords. 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 we start.
How do repairs to the shared parts of a tenement in Newhaven get organised?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Do you replace glass?
No. A misted unit has failed inside, and a glazier needs to replace it.
Are you insured?
Yes. We’re fully insured for every job we do.
Do you reseal glass shower screens?
We can. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
Can I choose the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many joints need doing and we leave things clean and tidy. For a tenement in Newhaven, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
How to get a quote
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work.
Advice
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Clear the conservatory gutters regularly
- Check the silicone on glass every year or so
- Do not leave a drip for the next storm
- Use a gentle glass cleaner and a soft cloth
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we will find out which.
Common problems we fix in Newhaven
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’re asked about most:
- Silicone pulling away from the glass
- Sealant that was laid over old silicone and failed
- Glass-to-glass joints that have split
- Water tracking down the inner face of the glass
For site and facilities teams at buildings such as Trinity Academy, the mastic around its windows and doors needs looking after like any other building’s.

Leave it or put it right?
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before you notice. Scottish rain finds any gap around a frame or wall joint, and in Newhaven, damp can spread through stone and plaster before anyone sees it.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Frames and glazing around Newhaven
Newhaven is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. 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.
For landlords with property near Edinburgh Waverley station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to Newhaven Parish Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
