Surface by surface
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. They’re resealed with a suitable sealant.
Rooflights
Rooflight leaks can come from the sealant or the roof. We find the cause first.
Glazing silicone for homes and businesses in Lenzie
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. Common call-outs are for shower screens leaking along the wall or tray and water running down inside the glass, across rooflights, glass-to-frame joints and conservatory frames.
In a town like Lenzie, stone-built older streets generally sit alongside harled houses and newer estates, so windows range from sash and case in older buildings to uPVC on newer homes. Each needs the right sealant against the right wall.
We stand behind the work with a 12-month guarantee.

What affects the quote in Lenzie
The quote reflects the job in front of us. We take into account:
- How many rooms, windows or areas are involved
- The type of sealant required
- How easy the joints are to reach
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- Roughly how big the job is
- Photos by email, if that is easy
- Where the property is
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved and send you a clear quote.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Rotten or badly damaged frames
- Glass that needs replacing
- Water coming through the roof rather than a sealant joint
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Glass balustrade bases
- Rooflights
- Conservatory frames
- Glass-to-glass joints
- Glass-to-frame joints
- Shower screens
DIY versus a professional finish
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 doesn’t work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why it’s worth doing now in Lenzie
A quick bead over the old sealant might stop a drip for a while, but silicone doesn’t stick to silicone and water soon finds its way back. A proper reseal is the lasting answer. Scottish weather finds any gap, and in a town like Lenzie, failed outside joints soon let damp into walls. Indoors, failed sealant lets water into floors and ceilings.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Advice
What we’re called out for in Lenzie
Some conservatory leaks aren’t sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That’s why we trace the leak first.
Any of these means the joints need attention:
- Conservatory leaks at frame and glazing joints
- Stained, discoloured glazing silicone
- Water tracking down the inner face of the glass
- Split or lifting silicone on glass
If you look after a building such as Kirkintilloch High School, its window and door frames need their mastic kept sound, just like a home’s.
What to look for in a quote
- What happens if they find a problem under the old sealant
- The length of the guarantee
- What preparation is included

Frames and glazing around Lenzie
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Lenzie is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for glazing joints and frame seals to keep out.
Letting a property close to Lenzie station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. Homes close to Lenzie Old Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Lenzie questions
I let a flat near Lenzie station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is there a guarantee on glazing silicone in Lenzie?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Can you reseal a frameless shower screen?
We can. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
Why not top up the existing silicone?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Will resealing stop my conservatory leaking?
Often, if the leak is at a sealant joint. We find where the water gets in first, so you know what you are paying for.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
