- New silicone smeared over old sealant
Do you need glazing silicone in Longformacus?
The wrong sealant is a common cause. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
Look out for any of the following:
- New silicone smeared over old sealant
- Mouldy sealant around glass panels
- Rooflight joints letting water in
- Failed joints on frameless glass
In the older streets around Longformacus Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before you book
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- How long to leave it before use
- How much experience the applicator has
How we handle glazing silicone in Longformacus
Glass and frames expand and contract differently, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. Typical jobs include black or yellowed silicone on glass joints and failed sealant around rooflight glass, across glass-to-glass joints, conservatory frames and shower screens.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most jobs and we leave things clean and tidy. Outside jobs in Longformacus need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Advice
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Use a gentle glass cleaner and a soft cloth
- Wipe the screen down after showering
- Use gentle products around the joints
- Keep air moving in the conservatory
Check the joints once a year. Catching a split early keeps the repair small.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
What affects the quote in Longformacus
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- The old material and how stubborn it is
- The number of rooms or windows
- Working hours on commercial sites
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
What we need to know
To make quoting easier, let us know:
- The rough size of the job
- How we’d reach the joints
- A few pictures by email, if you can
- The type of property
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.
When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before we start. It won’t solve:
- Water coming through the roof rather than a sealant joint
- Condensation trapped between two panes
- Cracked or broken glass
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.
Surfaces we seal
- Shower screens
- Rooflights
- Glass-to-frame joints
- Glass-to-glass joints
- Glass balustrade bases
- Conservatory frames
Why deal with it now?
Topping up old silicone can look like a fix, but new silicone will not bond to old, and the leak generally returns. Cutting out and resealing properly lasts. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Where do you work from?

Can you quote for more than one area?

What guarantee do I get?

Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you reseal glass shower screens?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
DIY versus a professional finish
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.
If you are 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 does not work out, we can still put it right.
Windows and doors in Longformacus
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 failed outside joints work against that.
In and around Longformacus, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
